Automotive load dump resistor | Thin Film Resistor Manufacturer | FIRSTOHM

In automotive systems, electronics must pass the ISO7637 EMC transient test(Pulse 5a/5b) to verify that the automotive electronics will not suffer from spikes and malfunction. In response to the surge immunity required by ISO7637 pulse 5a, a TVS function higher than pulse 5b must be selected to pass the test.FIRSTOHM is providing the best solution for passing the pulse 5a test. It is recommended to use an anti-surge resistor to reduce the impact of the surge on the circuit, as follows: FIRSTOHM is a high performance 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.
