Box 5928 • Greenville, SC 29606 • 864-963-6300 • www.kemet.com C1065_X1_440 VAC_Y2_300 VAC • 1/13/2017 8 Radial Leaded Ceramic Disc Capacitors Safety Standard Recognized, 900 Series, Encapsulated, AC Type, X1 440 VAC/Y2 300 VAC (Industrial Grade) Table 2 – Performance & Reliability: Test Methods and Conditions cont'd Item Specification Test Method High Temperature Life Appearance No visual defect Impulse Voltage: Each individual capacitor is subjected to three 5 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 throughout the test. The capacitors are subjected to AC 510 Vrms. Each hour the voltage is increased to 1,000 Vrms for 0.1 seconds. Capacitance Change Y5P, Y5V and Y5U: Within ±20% SL: Within ±3 or ±0.3 pF, whichever is larger. IR 3,000 MΩ minimum SL: 1,000 MΩ minimum Dielectric Strength No failures Flame Test The capacitor flame extinguishes as follows: Cycle Time 1 ~ 4 30 seconds maximum 5 60 seconds maximum The capacitor is exposed to a flame for 15 seconds and then removed for 15 seconds. This test is repeated for 5 cycles. 76 Capacitor Flame 38 127 20º Gas Burner (Unit:mm) Active Flammability The cheesecloth should not ignite. The capacitors are individually wrapped in at least one, but not more than two, complete layers of cheesecloth. They are then subjected to 20 discharges. The interval between successive discharges is 5 seconds. The VAC is maintained for 2 minutes after the last discharge.
