IRC has developed a "capped" version of its cylindrical power resistor that delivers good thermal compliance and thermal isolation from circuit boards. Designated the SMC series, these rugged power Metal Glaze™ resistors are available in ratings up to 2 W. The SMC1 series resistors are rated for 1 W at 70° C, with resistance values from 0.1Ω to 1MΩ, in standard tolerances of ± 1%, ± 2% and ± 5%, with TCRs as low as 䔽 ppm/° C. The SMC2 Series resistors are rated for 2 W at 25° C, with resistance values from 0.2Ω to 2.2MΩ, in standard tolerances of ± 1%, ± 2% and ± 5%, with TCRs as low as ± 25 ppm/° ºC. Operating temperature range is from – 55° C to +150° C. All devices are RoHS compliant and suitable for high temperature soldering processes.
