The WSC0002 has greater pulse capability than WSC4527 due to differences in internal construction. The non-inductive WSN has greater pulse capability for the same size WSC because the second layer of wire increases the wire mass available to withstand pulse energy without exceeding temperature limits. Follow pulse graphic link for more information regarding capability PERFORMANCE TEST CONDITIONS OF TEST TEST LIMITS Thermal shock -55 °C to +150 °C, 1000 cycles, 15 min at each extreme ± 0.5 % + 0.05  Short time overload 5 x rated power for 5 s ± 0.2 % + 0.05  Low temperature storage -65 °C for 24 h ± 0.2 % + 0.05  High temperature exposure 1000 h at + 275 °C (+175 °C for WSC01/2) ± 0.5 % + 0.05 Bias humidity +85 °C, 85 % RH, 10 % bias, 1000 h ± 0.2 % + 0.05  Mechanical shock 100 g’s for 6 ms, 5 pulses ± 0.1 % + 0.05  Vibration Frequency varied 10 Hz to 500 Hz in 1 min, 3 directions, 9 h ± 0.1 % + 0.05  Load life 1000 h at rated power, +70 °C, 1.5 h “ON”, 0.5 h “OFF” ± 1.0 % + 0.05  Resistance to solder heat +260 °C solder, 10 s to 12 s dwell, 25 mm/s emergence ± 0.5 % + 0.05  PACKAGING REEL MODEL TAPE WIDTH DIAMETER PIECES/REEL CODE WSC01/2 12 mm/embossed plastic 330 mm/13" 2000 EA/TA WSC2515 16 mm/embossed plastic 330 mm/13" 2000 EA/TA WSC0002, WSC4527 24 mm/embossed plastic 330 mm/13" 1200 EA/TA WSC6927 32 mm/embossed plastic 330 mm/13” 725 EA/TA Notes • Embossed carrier tape per EIA-481 • Additional packaging details at www.vishay.com/doc?20051 Revision: 11-Feb-2019 3 Document Number: 30102 For technical questions, contact: ww2bresistors@vishay.com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
