Ignition Noise Suppression Resistor (ISW) is a wirewound resistor dedicatedly designed for engine ignition systems for automotive(vehicle) and motorcycle, ISW can sustain high voltage spark over resistor because made with proprietary ceramic composite which can withstand high-voltage surge impacts with long-term stability, FIRSTOHM is one of few sources in the world capable of manufacturing such type of resistor.
Ignition Noise Suppression Resistor (ISW) features a power rating of 0.5W、2W and 3W, resistances range from 1K ohm to 5K ohm. MELF package is an SMD-enabled structure, it's better in heat dissipation and a stronger mechanical structure to endure vibration and thermal shock.
FIRSTOHM is able to design wire wound resistors according to customer's requirements with high quality and reliability since 1969, manufacture in TAIWAN and ISO9001/ISO14001 certificated.
