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.

General Information
Token MELF Offers Designer a Greater Choice
Token Electronics is now offering the complete range of MELF products, comprising DIN-0411,
DIN-0309, DIN-0207, DIN-0204 and DIN-0102. This high stability, close-tolerance MELF resistors
have a footprint very close to comparable chip resistors but maintain their tolerance and deliver higher
stability over a wider temperature range.
Where applications require even tighter tolerance, Token offer Ultra Precision range in the RJM
package, with values from 0.1Ω ~ 22MΩ, tolerance from ±5% down to as low as ±0.05% and TC from
±50ppm/℃ to ±5ppm/℃.
For high pulse load and high-frequency applications, Token Electronics offer specialized MELF
resistor. The high pulse load resistors are metal glaze film RGM, available in values from 50KΩ ~
22MΩ and ±0.5% precision tolerance, for 0.125 W ~ 3W applications.
High-frequency RFM resistors are available for RF microwave applications where impedance change
due to the parasitic inductance of regular resistors is not acceptable.
Chip Resistor Alternatives
In very low resistance values, between 0.1Ω and 475Ω, not usually offered by conventional chip
resistors, these are available in RJM72P 0102, RJM73P 0204, RJM74P 0207 and standard RJM18M
0411 MELF precision packages.
All MELF-type resistors are available on blister tape for automated placement and maintain their high
stability, high precision characteristics when exposed to soldering temperatures and operating stresses
including moisture, vibration, humidity and temperature variation within the specified range.
This makes them suitable for a wide range of applications, from laboratory and prototyping work to
installation in hostile environments such as airframe or under-bonnet areas, exposed parts of vehicles,
or other places where electronic sensing and controls must be installed.
