Why is the surge capability of MELF resistors much higher than chip resistors? | Thin Film Resistor Manufacturer | FIRSTOHM

Many electronic circuits encounter high-pulse loads. Due to its unique cylindrical design, the resistance area of MELF resistors is larger than chip resistors so that they can withstand higher pulse energy. FIRSTOHM is a high reliability 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 55 years of industry experience for resistors design and manufacturing facility.
