Product Overview
The SMG Series High Voltage Pulse Resistor is a surface-mount metal glaze resistor engineered for high-voltage and pulse-intensive electronic applications. Its flameproof UL94V-0 molded package, anti-sulfuration construction, and metal glaze resistive element provide reliable electrical performance in high-temperature, high-humidity, and sulfur-containing environments.
Designed to withstand repetitive pulse loads and lightning surge events, the SMG series complies with IEC 60065 pulse loading requirements and has been evaluated according to IEC 61000-4-5 lightning surge conditions. With working voltages up to 5000 V (3WL), insulation resistance of 10,000 MΩ, and excellent mechanical strength, it is an ideal choice for demanding industrial and power electronic systems.
