Single Surge Performance
Metal Film MELF Precision Resistor-MMP series, is showing the surge performance from 10uS to 1S.
Surge Power Derating Curve
• Above graph is accurate for NON REPETITIVE applications operating in an ambient temperature of 70°C or less. For temperatures above
70°C, the graph power must be derated further linearly down to zero at 125°C. • For applicable surge power in continuous-surge applications please see SURGE POWER DERATING CURVE above.

Vehicle Grade Metal Film MELF Resistor-MM102
Metal Film MELF Resistor (MM102) is in a cylindrical shape and features Metal Electrode Leadless Faces, with a power rating of 0.2W and a resistance range from 0.22 ohm to 2.2M ohm. The dimension is the same as flat chip resistors (0805), providing superior reliability and stability, along with better heat dissipation than chip resistors, and a stronger mechanical structure to endure vibration and thermal shock. It is AEC-Q200 certified.
Stabilized Film Power MELF Resistor-SFP
The Stabilized Film Power MELF Resistor (SFP series) is optimized for heat dissipation, featuring a low temperature coefficient and tolerances, and supports a power rating from 0.4W to 3W, with a resistance range from 0.5 ohm to 10M ohm. The resistance is most stabilized after long-term operation due to its superior metal film coating on the cylindrical ceramic rod. Its SMD-enabled structure with MELF style provides better heat dissipation than a chip resistor, along with a stronger mechanical structure to withstand vibration and thermal shock. The Firstohm SFP series serves as the best alternative to MMA0204/MMB0207.
Metal Film MELF Resistor-MM
The Metal Film MELF Resistor(MM) is designed in a cylindrical shape and Metal Electrode Leadless Face. Its dimensions are the same as SMD chip resistors, with a rated power from 0.16W to 0.5W and resistance range from 0.51 ohm to 10M ohm. It has superior reliability and stability since the MELF package is better in heat dissipation than chip resistor, and it has a stronger mechanical structure to endure vibration and thermal shock.
