Carbon Film MELF - RDM SeriesThumbnail Gallery
Commercial grade low power carbon film resistors offer high quality performance for applications that do not require surge protection or precision tolerances.
Providing design engineers with an economical power resistor with high quality performance, Token Electronics now offers commercial grade low power carbon film resistors. Designated the RDM Series, the conformally coated resistors offer high quality performance for applications that do not require surge protection or precision tolerances.
The commercial grade carbon melf resistors are available in flame retardant packaging and have ideal specifications for consumer electronic or electrical devices. The RDM Series resistors offer a wide resistance range for devices with power ratings below 1W, delivering high quality performance for general purpose applications.
The RDM Series resistors are ideal for general use applications including electrical equipment, small appliances and consumer electronics, such as televisions and other high-volume products.
The RDM Series film resistors feature power ratings from 0.125 to 1W, with a resistance range from 1 Ω to 1M Ω. Standard tolerances for the devices are to ±2% and ±5% with TCRs as low as ±300ppm/°C for values of 1K Ω or less. Maximum working voltage ranges from 200V to 350V.
