IRC's Metal Film Resistors' Epoxy Coating Provides Superior Moisture Protection for Industrial Applications
Commercial grade resistors feature low noise and voltage coefficients; low TCRs...
LAS VEGAS, NV (May 14, 2007) - Providing design engineers with an economical device that yields stable performance, TT electronics IRC Wire and Film Technologies Division now offers a series of commercial grade metal film resistors. Designated the CMF Series, the metal film resistors feature an extended resistance range up to 1MΩ, with TCRs down to ±100ppm/°C as well as low noise and voltage coefficients.
"The epoxy coating we use on our metal film resistors provides superior moisture protection," said David Winkler, product manager for IRC's Wire and Film Technologies Division. "The conformal coating, along with other specifications that result in a stable performance, make the CMF resistors ideal for power supply and industrial electronics applications."
The CMF Series resistors also feature low noise and utilize standard EIA color-coding. A flame retardant version is also available.
The CMF Series metal film resistors feature power ratings from 0.125W to 3W, with a resistance range from 10Ω to 1MΩ and standard tolerance to ±1%, with TCRs as low as ±100ppm/°C. Maximum working voltage ranges from 200V to 500V, with dielectric withstanding voltage from 400V to 1000V, depending on power rating.
Typical pricing for the CMF Series resistors is $.0062 each for 1/4 watt in quantities of 75,000 pieces. Lead time is from stock to 6 weeks.
