The test procedures, which are integrated into the production process, were developed after long research and are based on the highly developed semiconductor industry test procedures and equipment. These measures help AVX/Kyocera to produce a consistent and high yield line of products. • Final Quality Inspection: Finished parts are tested for standard electrical parameters and visual/mechanical characteristics. Each production lot is 100% evaluated for electrical resistance. In addition, each production lot is evaluated on a sample basis for: • Insulation resistance (post fusing) • Blow time for 2 x rated current • Endurance test: 125°C, rated current, 4 hours Component pads must be designed to achieve good joints and minimize component movement during soldering. Pad designs are given below for both wave and reflow soldering. The basis of these designs are: a. Pad width equal to component width. It is permissible to decrease this to as low as 85% of component width but it is not advisable to go below this. b. Pad overlap 0.5mm. c. Pad extension 0.5mm for reflow. Pad extension about 1.0mm for wave soldering. HANDLING AND SOLDERING SMD chips should be handled with care to avoid damage or contamination from perspiration and skin oils. The use of plastic tipped tweezers or vacuum pick-ups is strongly recommended for individual components. Bulk handling should ensure that abrasion and mechanical shock are minimized. For automatic equipment, taped and reeled product is the ideal medium for direct presentation to the placement machine. CIRCUIT BOARD TYPE PREHEAT & SOLDERING The rate of preheat in production should not exceed 4°C/second. It is recommended not to exceed 2°C/ second. Temperature differential from preheat to soldering should not exceed 150°C. For further specific application or process advice, please consult AVX. HAND SOLDERING & REWORK Hand soldering is permissible. Preheat of the PCB to 100°C is required. The most preferable technique is to use hot air soldering tools. Where a soldering iron is used, a temperature controlled model not exceeding 30 watts should be used and set to not more than 260°C. Maximum allowed time at temperature is 1 minute. COOLING All flexible types of circuit boards may be used (e.g. FR-4, G-10). For other circuit board materials, please consult factory. After soldering, the assembly should preferably be allowed to cool naturally. In the event of assisted cooling, similar conditions to those recommended for preheating should be used.

The factor of pre-arc I2t, however, requires clarification. The proper design for pre-arc I2t is presented by way of example. DESIGN PARAMETERS 1. Operating Temperature The Accu-Guard® is specified for operation in the temperature range of -55°C to +125°C. Note, however, that fusing current is sensitive to temperature. This means that the fuse must be derated or uprated at circuit temperatures other than 25°C: Environmental Temperature Accu-Guard® Current Carrying Capacity* F0402G F0603G F0402E, F0603E F0805B, F1206A, F0805B 2.50A F1206B & 3.00A F0603C F0612D -55°C to -11°C 1.07 x IR 1.07 x IR 1.07 x IR -10°C to 60°C IR IR IR 1.07 x IR 1.07 x IR 61°C to 100°C 0.85 x IR 0.93 x IR 0.90 x IR 0.90 x IR 0.80 x IR 101°C to 125°C 0.80 x IR 0.90 x IR 0.90 x IR 0.75 x IR 0.75 x IR IR IR *As a function of nominal rated current, IR. 2. Circuit Voltage Maximum Voltage: Accu-Guard® is specified for circuits of up to rated voltage. Accu-Guard® will successfully break currents at higher voltages as well, but over voltage may crack the fuse body. Minimum Voltage: Accu-Guard® cannot be used in circuits with voltage of about 0.5V and less. The internal resistance of the fuse will limit the fault current to a value which will prevent reliable actuation of the fuse (<2 x rated current). 5. Switch-on and Other Pulse Current Many circuits generate a large current pulse when initially connected to power. There are also circuits which are subject to momentary current pulses due to external sources; telephone line cards which are subject to lightning-induced pulses are one example. These current pulses must be passed by the fuse without causing actuation. These pulses may be so large that they are the determining factor for choosing the Accu-Guard® current rating; not necessarily steady state current. In order to design for current pulses, the concept of fuse pre-arc Joule integral, I2t, must be understood. Fuse current rating is defined by the requirement that 2 x IR will cause actuation in <5 seconds. This rating does not indicate how the fuse will react to very high currents of very short duration. Rather, the fusing characteristic at very high currents is specified by I2t-t curves (or I2t-I). I2t expresses the amount of energy required to actuate the fuse. Total I2t expresses the total energy which will be passed by the fuse until total cessation of current flow. Pre-arc I2t expresses that energy required to cause large irreversible damage to the fuse element (Total I2t = pre-arc I2t + arc I2t). If the Joule integral of the switch-on pulse is larger than the fuse pre-arc I2t, nuisance actuation will occur. In order to choose the proper Accu-Guard® current rating for a given application, it is necessary to calculate the I2t Joule integral of the circuit switch-on and other current pulses and compare them to the Accu-Guard® I2t-t curves. An AccuGuard® fuse must be chosen such that the pulse I2t is no more than 50% of the pre-arc I2t of the prospective fuse. Pre-arc I2t of the Accu-Guard® fuses is well characterized; I2t-t and I2t-I graphs are in this catalog. The problem is calculating the I2t of the circuit current pulses. This concept is not familiar to most engineers. Correct calculation of pulse Joule integral and subsequent choice of Accu-Guard® current rating is illustrated by way of the attached examples. 3. Maximum Fault Current Accu-Guard® is fully tested and specified for fault currents up to 50A. Accu-Guard® will successfully break currents above 50A, but such over current may crack the fuse body or damage the fuse terminations. 4. Steady-State Current The Accu-Guard® current rating is based on IEC Specification 127-3. In accordance with this international standard, Accu-Guard® is specified to operate at least 4 hours at rated current without fusing (25°C). Engineering tests have shown that F0805B and F1206A/B Accu-Guard® will in fact operate at least 20,000 hours at rated current without fusing (25°C). 31 Accu-Guard® SMD Thin-Film Fuse 2.

Sine wave current pulse The Joule integral for sine wave pulse is [(Imax.)2 x t]/2, l max. see Fig. 1a. l max. t t Fig. 1a. Sine wave pulse parameters for Joule integral calculation, example #1. Thus, for the current pulse in Figure 1b, the Joule integral is [(4.8A)2 x 7.7 x 10-6 sec]/2 = 8.9 x 10-5 A2 sec. Fig. 2a. Triangular pulse parameters for Joule integral calculation, example #2. Thus, for the current pulse in Figure 2b, the Joule integral is [(1.5A)2 x 3 x 10-3 sec]/3 = 2.25 x 10-3 A2sec. 10 μsec/div 2 msec/div 0.5A/div 1A/div Fig. 1b. Sine wave pulse, example #1. Fig. 2b. Triangular pulse, example #2. The pulse duration is 7.7μsec. We must find a fuse that can absorb at least 8.9 x 10-5 X 2 = 1.8 x 10-4 A2sec Joule integral within 7.7 μsec without actuation. According to the I2t graph on page 6, pre-arcing Joule integral is 2.3x10-4 A2sec for the 0.5A fuse, which is slightly more than needed. The next lower rating (0.375A), has only 6x10-5 A2sec, which is not enough. Therefore, 0.5A fuse should be chosen for this application, see Figure 1c. The pulse duration is 3 msec. In the I2t graph on page 6, prearcing Joule integral for 3 msec pulse is 4 x 10-3A2sec for the 0.5A fuse (not enough) and 2 x 10-2 for the 0.75A fuse (more than enough). Therefore, 0.75A fuse should be chosen for this application, see Figure 2c.

Complex current pulse 6. Switch-on pulse and steady-state current If the pulse consists of several waveforms, all of them should be evaluated separately, and then the total Joule integral should be calculated as well. In Figure 6a, the switch-on pulse is a triangle pulse with a 5.1 x 10-3 A2sec Joule integral of 5 msec duration; the 0.75A fuse will meet this requirement, see Figure 6b. 200 μsec/div 2 msec/div 2A/div Fig. 5a. Complex pulse, example #5. In Figure 5a, the Joule integral for the first triangle is [(4.67A)2 x 294 x 10-6sec]/3=2.14 x 10-3 A2sec and 0.75A fuse should meet this condition, see Figure 5b.

Pre-arcing I2t Maximum I2t design rule X I2t for sample switch-on pulse The Joule integral for the second triangle is [(5.33A)2 x 269 x 10-6sec]/3 = 2.55 x 10-3 A2sec, and 0.75A fuse is suitable for this case also, see Figure 5b. However, for the whole pulse, the Joule integral is 4.7 x 10-3 A2sec, and the total duration is 563 μsec. For the 0.75A fuse, the Joule integral is only 8.6 x 10-3 A2sec for this pulse duration, so the 1A fuse should be chosen for this application, see Figure 5b. 34 0.5A/div 1 10 Fig. 6b. Choice of 0.75A fuse, example #6. Pre-arcing I2t Maximum I2t design rule X I2t for sample switch-on pulse The steady-state current is 0.5A, and 1A fuse is typically recommended to meet the steady-state condition. Based on steady-state current, the 1A fuse should be chosen for this application.
