IRC Offers Flameproof Vertical Mount Power Resistors for Use in Harsh Environments

IRC Inc. announced that it now offers commercial grade cement housed vertical mount power wirewound and film resistors. Designated the CVW (wirewound) and CVF (film) Series, the resistors' specifications are well-suited for high volume and high temperature applications.

"The vertical mount configuration gives the device a minimal footprint, making it suitable for applications where PC board space is at a premium," said David Winkler, Product Manager for IRC’s Wire and Film Technologies Division. "With the extended resistance range and high temperature rating, the resistors can be specified for operation in harsh environments."

The CVW and CVF Series resistors are suitable for industrial applications, including power electronics circuits, voltage dividers, power supplies and motor controllers. The CVW Series wirewound resistors feature a resistance range from 0.1 to 910Ω, while the CVF Series film resistors have a resistance range of 28 to 200KΩ. Standard tolerances for both devices are to ±5% and ±10%, with TCRs of ±400ppm/°C at less than 20Ω and ±350ppm/°C at 20Ω and above. Operating temperature range is -55 to +275°C.

Typical pricing for the CVW and CVF Series resistors is $.085 to $0.17 each, depending on R-values, in quantities of 10K pieces. Lead time is from stock to 6 weeks.
