IRC new thick-film chip resistor series with resistance values to 100 megohms provide design engineers with a robust device that is well suited for a variety of high-voltage, harsh environment applications. Designated as the HVC series, the resistors are rectangular and can be supplied in standard 1206, 2010 and 2512 package sizes, so that automatic handling methods can be employed.

The robust construction and electrical specifications make the HVC series chip resistors ideal for high-voltage power supplies (photomultiplier-tube amplifiers) and military equipment (night-vision cameras, x-ray equipment).

The wrap-around terminations have an electroplated nickel barrier and either tin/lead or RoHS-compliant, matte-tin finish, ensuring excellent leach resistance properties and solderability.

The HVC series resistors feature a resistance range from 100 kilohms to 100 megohms, with tolerances of 0.5 percent, 1 percent, 2 percent, and 5 percent. Continuous voltage ratings are up to 3 kV, with a maximum overload voltage to 4.5 kV. Power ratings for the 1206, 2010 and 2512 resistors are 0.3 W, 0.5 W and 1 W, respectively, with rated voltages of 1000 V, 2000 V and 3000 V. The HVC series also offer a low voltage coefficient (VCR) of less than -25 ppm and a low temperature coefficient (TCR) of ±100 ppm/°C, with an operating temperature range of -55 °C to +155 °C.

IRC can also produce devices outside this range of specifications to meet special customer requirements.

Typical pricing for the HVC series resistors is approximately $0.50 in minimum order quantities of 10,000 pieces. Lead time is from stock to 8 to 9 weeks.
