Refer to the following for reliable circuit design. 1. Expecting Reliability SVS series tantalum chip capacitors are typically applied to decoupling, blocking, bypassing and filtering. The SVS series has a very high reliability (low failure rate) in the field. For example, the maximum field failure rate of an SVS series capacitor with a DC rated voltage of 16 V is 0.0004% / 1000 hour (4 Fit) at an applied voltage of 5 V, operating temperature of 25˚C and series resistance of 3 Ω. The maximum failure rate in the field is estimated by the following expression : 3 λ = λ0 V V0 ×2 T-T0 10 λ : Maximum field failure rate λ 0 : 1% /1000 hour (The failure rate of the SVS series at the full DC rated voltage at operating temperature of 85˚C and series resistance of 3 Ω.)

Series resistance As shown in Figure 1, reliability is increased by inserting a series resistance of at least 3 Ω/ V into circuits where current flow is momentary (switching circuits, charge/discharge circuits, etc). If the capacitor is in a low-impedance circuit, the voltage applied to the capacitor should be less than 1/2 to 1/3 of the DC rated voltage.

Ripple voltage The sum of DC voltage and peak ripple voltage should not exceed the DC rated voltage of the capacitor.

For higher temperature, permissible ripple voltage shall be derated as follows. Permissible voltage at 50˚C = 0.7 × permissible voltage at 25˚C Permissible voltage at 85˚C = 0.5 × permissible voltage at 25˚C Permissible voltage at 125˚C = 0.3 × permissible voltage at 25˚C 4. Reverse voltage Because the capacitors are polarized, reverse voltage should not be applied. If reverse voltage cannot be avoided because of circuit design, the voltage application should be for a very short time and should not exceed the following. 10% of DC rated voltage at 25˚C 5% of DC rated voltage at 85˚C 1% of DC rated voltage at 125˚C 12 SVS SERIES 5. Mounting (1) Direct soldering Keep in mind the following points when soldering the capacitor by means of jet soldering or dip soldering: (a) Temporarily fixing resin Because the SVS series solid tantalum capacitors are larger in size and subject to more force than the chip multilayer ceramic capacitors or chip resistors, more resin is required to temporarily secure the solid tantalum capacitors. However, if too much resin is used, the resin adhering to the patterns on a printed circuit board may adversely affect the solderability. (b) Pattern design b a c a Case a b c P 2.2 1.4 0.7 The above dimensions are for reference only. If the capacitor is to be mounted by this method, and if the pattern is too small, the solderability may be degraded. (e) Temperature and time Keep the peak temperature and time to within the following values: Solder temperature ....... 260˚C max. Time ....... 5 seconds max. Whenever possible, perform preheating (at 150˚C max.) for smooth temperature profile. To maintain the reliability, mount the capacitor at a low temperature and in a short time whenever possible. (d) Component layout If many types of chip components are mounted on a printed circuit board which is to be soldered by means of jet soldering, solderability may not be uniform over the entire board depending on the layout and density of the components on the board (also take into consideration generation of flux gas). (e) Flux Use resin-based flux. Do not use flux with strong acidity. 13 SVS SERIES (2) Reflow soldering Keep in mind the following points when soldering the capacitor in a soldering oven or with a hot plate: (a) Pattern design (In accordance with IEC1182) X G Z Case G max. Z min. X min. P 0.5 2.6 1.2 The above dimensions are recommended. Note that if the pattern is too big, the component may not be mounted in place. (b) Temperature and time Keep the peak temperature and time to within the following values: Solder temperature …… 260˚C max. Time : 10 seconds max. Whenever possible, perform preheating (at 150˚C max.) for smooth temperature profile. To maintain the reliability, mount the capacitor at a low temperature and in a short time whenever possible. The peak temperature and time shown above are applicable when the capacitor is to be soldered in a soldering oven or with a hot plate. When the capacitor is soldered by means of infrared reflow soldering, the internal temperature of the capacitor may rise beyond the surface temperature. (3) Using soldering iron When soldering the capacitor with a soldering iron, controlling the temperature at the tip of the soldering iron is very difficult. However, it is recommended that the following temperature and time be observed to maintain the reliability of the capacitor: lron temperature …… 300˚C max. Time ……………………… 3 seconds max. Iron power …………… 30 W max. 14 SVS SERIES 6. Cleaning Generally, several organic solvents are used for flux cleaning of an electronic component after soldering. Many cleaning methods, such as immersion cleaning, rinse cleaning, brush cleaning, shower cleaning, vapor cleaning, and ultrasonic cleaning, are available, and one of these cleaning methods may be used alone or two or more may be used in combination. The temperature of the organic solvent may vary from room temperature to several 10˚C, depending on the desired effect. If cleaning is carried out with emphasis placed only on cleaning effect, however, the marking on the electronic component cleaned may be erased, the appearance of the component may be damaged, and in the worst case, the component may be functionally damaged. It is therefore recommended that the SVS series solid tantalum capacitor be cleaned under the following conditions: [Recommended conditions of flux cleaning] (1) Cleaning solvent ……… Chlorosen, isopropyl alcohol (2) Cleaning method …… Shower cleaning, rinse cleaning, vapor cleaning (3) Cleaning time ………… 5 minutes max. ∗ Ultrasonic cleaning This cleaning method is extremely effective for eliminating dust that has been generated as a result of mechanical processes, but may pose a problem depending on the condition. As a result of an experiment conducted by NEC, it was confirmed that the external terminals of the capacitor were cut when it was cleaned with some ultrasonic cleaning machines. The cause of this phenomenon is considered metal fatigue of the capacitor terminals that occurred due to ultrasonic cleaning. To prevent the terminal from being cut, decreasing the output power of the ultrasonic cleaning machine or shortening the cleaning time may be a possible solution. However, it is difficult to specify the safe cleaning conditions because there are many factors involved such as the conversion efficiency of the ultrasonic oscillator, transfer efficiency of the cleaning bath, difference in cleaning effect depending on the location in the cleaning bath, the size and quantity of the printed circuit boards to be cleaned, and the securing states of the components on the boards. It is therefore recommended that ultrasonic cleaning be avoided as much as possible. If ultrasonic cleaning is essential, make sure through experiments that no abnormality occur as a result of the cleaning. For further information, consult NEC. 7. Others (1) Do not apply excessive vibration and shock to the capacitor. (2) The solderability of the capacitor may be degraded by humidity. Store the capacitor at (–5 to +40˚C) room temperature and (40 to 60% RH) humidity. (3) Exercise care that no external force is applied to the tape packaged products (if the packaging material is deformed, the capacitor may not be automatically mounted by a chip mounter). 15 SVS SERIES No part of this document may be copied or reproduced in any form or by any means without the prior written consent of NEC Corporation.
