Duration/Solder Temperature: 3.5±0.5 seconds/350°C ±10°C or 10±1 seconds/260°C ±5°C Molten Solder 1.5 to 2.0 mm Capacitor Thermal Screen Pre-treatment: Capacitor is stored at 85°C ±2°C for 1 hour and then placed at room condition1 for 24±2 hours before initial measurements. Post-treatment: Capacitor is stored for 1 to 2 hours at room condition1. IR 1,000 MΩ Dielectric Strength Per item 1 Capacitance Within ±10% Soldering Effect (Preheat) Appearance No visual defect Capacitor is stored at 120°C +0/−5°C for 60+0/−5 seconds. Then, as shown in the figure below, the lead wires are immersed in molten solder up to 1.5 mm (+5/−0mm) from the end of the epoxy meniscus (root of lead wire). Duration/Solder Temperature: 7.5 +0/−1 seconds/260°C ±5°C Molten Solder 1.5 to 2.0 mm Capacitor Thermal Screen Pre-treatment: Capacitor is stored at 85°C ±2°C for 1 hour and then placed at room condition1 for 24±2 hours before initial measurements. Post-treatment: Capacitor is stored for 1 to 2 hours at room condition1. IR 1,000 MΩ Dielectric Strength Per item 1 Capacitance Within ±10% Biased Humidity Appearance No visual defect Steady State Humidity: Load Humidity: Capacitance Temperature Characteristics Capacitance Change Y5U Within ±30% 90 to 95% humidity at 40°C ±2°C for 500 ±12 hours. Post Treatment: Capacitor is stored for 1 to 2 hours at room condition1. 90 to 95% humidity at 40°C ±2°C for 500 ±12 hours with full rated voltage applied. Post Treatment: Capacitor is stored for 1 to 2 hours at room condition1. DF 5.0% maximum IR 3,000 MΩ minimum Dielectric Strength No failures High Temperature Life Appearance No visual defect Impulse Voltage: Each individual capacitor is subjected to three 8 kv impulses prior to life testing. PP U PR U Vp 0.9Vp 0.5Vp tr td Time td (uS) 46 47 tr (uS) 1.2 1.5 Cx (uF) 0.01 0.1 Capacitors are placed in a circulating air oven for a period of 1,000 hours. The air in the oven is maintained at a temperature of 125°C ±2°C throughout the test. The capacitors are subjected to AC 850 Vrms. Each hour the voltage is increased to 1,000 Vrms for 0.1 seconds. . Capacitance Change Within ±20% IR 3,000 MΩ minimum Dielectric Strength No failures 1 “Room Condition” is defined as follows: Temperature: 15 ~ 35°C/Humidity: 45 ~ 75%/Atmospheric Pressure: 86 ~ 106 kPa. |
