MELF Resistor Index
RFM series - MELF High frequency non-inductance Resistor
RGM series - Pulse Metal Glaze Film Power MELF Resistor
RJM series - Metal Film MELF Precision Resistor
RDM series - Carbon Film MELF Resistor

MELF is the abbreviation for Metal Electrode Leadless Face - a leadless cylindrical component that is metallized on two ends. It is designed majorly as a SMD component. Since manufacturing process of MELF resistor is more complex than flat-chip resistor, MELF resistor has its own advantages over flat-chip type.
TOKEN full line of high frequency non-inductance MELF RFM resistors meet RoHS Directives.

High frequency non-inductance MELF resistors RFM series, professional metal film MELF non-inductance resistors are the perfect choice for most fields of modern professional electronics where reliability and stability is of major concern as well as non-inductance. Resistance range: 25Ω to 200Ω. Tolerance range: ±0.5% to ±5.0%. Power dissipation rating at 70°C up to 0.75W. Small size. TOKEN offers competitive prices and are widely used Telecommunication, HF and pulse loading applications, Industrial electronics.
