Pulse Load High Voltage MELF Resister-PVM

The Pulse Load High Voltage MELF Resistor(PVM) features a power rating from 0.4W to 1W, with a resistance range from 300K ohm to 39M ohm, and tolerances of ±1%, ±2%, and ±5%. It has an SMD-enabled structure due to MELF packing 0204/0207. Its proprietary thin-film can handle much higher working voltage than general-purpose resistors, since it possesses an anti-surge feature coated on a cylindrical ceramic rod and is packed as a MELF resistor. The Pulse Load High Voltage MELF Resistor provides better thermal dissipation than chip resistors.

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.

Surge Safety Resistor-SSR

The Surge Safety Resistor (SSR series) features a power rating from 0.25W to 5W, with resistance ranging from 10 ohm to 330K ohm. Designed to replace carbon or ceramic composition resistors, the SSR series is a good choice for anti-surge applications such as fuel ignition systems, power charging/discharging circuits, and ECG cables to absorb harmful surge energy, thereby preventing the hazard of fire and circuit damage caused by surge energy with a flameproof coating. Products comply with RoHS requirements and do not contain substances of very high concern identified by the European Chemicals Agency.

Anti-Surge Wire Wound Resistors-SWA

The Anti-Surge Wirewound Resistor (SWA series) offers a power rating from 1W to 6W, with a resistance range from 100m ohm to 1.2K ohm. The enhanced weld spot is not broken by surge impact, and the alloy wire can absorb harmful surge energy, making it suitable for high surge applications such as rush current protection of power capacitors, motor start-up protection, car & motorcycle engine ignition, thereby preventing the hazard of circuit damage caused by surge energy.
