Carbon Film MELF Resistor
Carbon film MELF resistor, also known as carbon film wafer resistor (RDM series), is cylindrical lead‑free surface‑mount component. It adopts carbon resistive film deposited on ceramic core with metal end‑cap electrodes, combining the advantages of traditional axial carbon‑film resistor and SMD automatic assembly technology.
Manufactured by Guangdong Qingda Electronic Technology Co., Ltd., this series delivers outstanding heat dissipation and strong anti‑vibration performance compared with conventional flat chip resistors. With good pulse‑withstand property and competitive cost, it is widely adopted in mass‑production general‑purpose electronic equipment. The protective outer coating provides reliable protection against humidity and mechanical damage.
