IRC Offers Chip Resistors For Voltages Up To 3KV

June 23, 2008 by Jeff Shepard

IRC announced that it is now offering a thick film chip resistor with resistance values to 100mΩ. Designated the HVC series, the resistors are rectangular and feature high voltage operation in standard 1206, 2010 and 2512 package sizes, making them well suited for automatic handling methods.

"Along with the robust thick film construction, 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," said Gary Bleasdell, Thick Film Business Unit Director for IRC. "The overall construction allows the chip resistor to operate in harsh, high voltage environments, including those in medical and military applications."

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

The HVC series resistors feature a resistance range of 100KΩ to 1MΩ, with tolerances to 0.5, 1, 2, and 5%. Continuous voltage ratings are up to 3KV, with maximum overload voltage to 4.5KV. Power ratings for the 1206, 2010 and 2512 resistors are 0.3, 0.5 and 1W, respectively, with rated voltages of 1000, 2000 and 3000V. The HVC series also offer low Voltage Coefficient (VCR) of <-25ppm and low Temperature Coefficient (TCR) of ±100ppm/°C, with an operating temperature range of -55 to +155°C. IRC will also produce devices outside these specifications to meet 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.
