IRC's CMO Series of metal oxide resistors

TT electronics IRC Wire and Film Technologies Division has introduced the new CMO Series of commercial-grade metal oxide resistors that are designed to withstand high temperatures and electrical overloads.

The resistors are available in both standard and miniature sizes, with power ratings from 0.25W to 9W at 70C, and a maximum operating temperature of 240C.

Other product features include resistance leakage from 0.3-200, standard tolerances to 2 percent and TCRs to 350ppm/C. The devices meet EIA-RC2655A requirements, said the company.

"These metal oxide resistors offer a wide resistance range in a rugged, flameproof device capable of operating at sustained high ambient temperatures," said David Winkler, product manager for IRC's Wire and Film Technologies Division. "The availability of the CMO Series devices in miniature sizes makes it an ideal choice for engineers who need power resistors for applications with limited PCB space."

Supplied with a flame-retardant coating, the CMO Series resistors are being specified for industrial and power electronics applications that require stable high temperature performance in harsh environments.
