Chip Resistors Withstand High Voltage

TT electronics IRC Advanced Film Division’s pulse-withstanding chip resistors combine extended surge values with high voltage ratings. Designated the PWC Series, the resistors—ideal for power supplies and circuit protection devices—are available in 0805, 1206, 2010 and 2512 chip sizes.

In the 0805, 1206, 2010, and 2512 package sizes, the PWC Series resistors feature power ratings of 125 mW, 330 mW, 750 mW and 1.5 W, with maximum voltage ratings of 150 V, 200 V, 400 V and 500 V, respectively. Resistance range is from 1.0 Ω to 10 MΩ, with available tolerances from ±0.5% to ±5%. Absolute TCRs are ±100 ppm/°C at 10 Ω and higher, and ±200 ppm/°C at less than 10 Ω. Operating temperature range is -55°C to +155°C. IRC will also produce devices outside these specifications to meet customer requirements. Pricing for the PWC 2512 Series resistors is $0.39 each in quantities of 5000.
