Enhanced Film Power MELF Resistor ( 0.5W 1.8ohm 1%) | Automotive-Grade Resistors Manufacturer | FIRSTOHM

Enhanced Film Power MELF Resistor (EFP) 0.5W 1.8ohm 1% is SMD enabled structure with superior anti-surge capability, and the power dissipation is much better than chip resistors. In general usage, chip resistor is operating at 20%~30% of rated power, MELF resistor is operating at 50% of rated power. Therefore, the power density of MELF resistor is approximate 2 times of chip resistor. FIRSTOHM is a high-quality Enhanced Film Power MELF Resistor ( 0.5W 1.8ohm 1%), MELF resistors, SMD resistors, metal film resistors, surge resistors, wire wound resistors, precision resistors, High voltage resistors, high Power resistors, metal oxide resistor, thin film resistors, fixed resistors manufacturer from Taiwan since 1969. FIRSTOHM is one of the few companies who is able to design thin-film MELF resistors according to customer's requirements with high quality and reliability. We’re specialized in thin-film resistors since 1969, ISO9001/14001 certificated manufacturer. Over 50 years of industry experience for resistors design and manufacturing facility.
