The high frequency RFM specialty series of non-inductance

MELF resistor from Token Electronics has been extended to offer

more than GHz operation, making the devices more suitable for

high frequency RF applications.

They are the perfect choice in high frequency circuit designs

where the parasitic inductance of regular, helical trimmed resistors

cannot be accepted, but where also pulse energies apply. Typical

applications are in the fields of telecommunication equipment and

industrial electronics.

These high stability, non-inductance MELF resistors have a footprint very close to comparable chip

resistors but maintain their tolerance and deliver higher stability over a wider temperature range. Sizes

range from 5.7 × 2.1mm for the RFM74 MELF-0207, through 3.45 × 1.3mm for the RFM73

MELF-0204 down to 2.2 × 1.3mm for the RFM72 MELF-0102.

Production is strictly controlled and follows and extensive set of instructions established for

reproducibility. The groove on the metal alloy film of high grade ceramic rod is special designed to

achieve non inductance. The resistor elements are covered by a protective coating designed for

mechanical, electrical and climatic protection.

The terminations are covered with final pure tin plating for keeping perfect solder ability. Four or five

color code rings designate the resistance value and tolerance in accordance with IEC 60062.

Token's RFM MELF standard series can be a replacement for Vishay, IRC, EBG, KAO, and Panasonic

Precision Devices with more competitive price and short lead time. Contact us with your specific

needs. Please link to Token official website "Melf Resistors" for more information.

Non-Inductance MELF Resisters offer greater choice for

high frequency applications.
