Spark Gap Protectors (SPG) SCA Series Test Methods and Results Items Test Method Standard Measure starting discharge voltage (Vs) by gradually increasing applied DC voltage. Test current is 0.5mA DC Spark-over Voltage max. And the DC voltage ascends up within Insulation Resistance 100V/s(Vs＜1000V) or 500V/s(Vs≥1000V). Rate-of-change, within±30% Measure the insulation resistance across the terminal insulation resistance & capacitance, at regular voltage. But the test voltage doesn’t over conformed to rated spec. the DC spark-over voltage. Measure the electrostatic capacitance by applying a Capacitance voltage of less than 6V (at 1KHz) between terminals. ∣△Vs/Vs∣≤30% 10KV with 1500pf condenser is discharged through Static Life Characteristics of other items must meet 2KΩ resistor. 200 times at an interval of 10sec. the specified value 1.2/50μs & 8/20μs, 500A, electrically connected with Surge Current a resistor (1~2 Ω), ±5 times, each time interval 60 Capacity seconds.

Hand Soldering Solder iron temperature: 350±5℃ Heating time: 3 seconds max. General attention to soldering u High soldering temperatures and long soldering times can cause leaching of the termination, decrease in adherence strength, and the change of characteristic may occur. u For soldering, please refer to the soldering curves above. However, please keep exposures to temperatures exceeding 200℃ to fewer than 50 seconds. u Please use a mild flux (containing less than 0.2wt% CI). Also, if the flux is water soluble, be sure to wash thoroughly to remove any residue from the underside of components that could affect resistance. Cleaning When using ultrasonic cleaning, the board may resonate if the output power is too high. Since this vibration can cause cracking or a decrease in the adherence of the termination, we recommend that you use the conditions below: Frequency: 40kHz max. Output power: 20W/liter Cleaning time: 5 minutes max. SOCAY Electronics Co., Ltd.
