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.
