Core Product Lines
Thick Film Chip Resistors (CRCW Series) Manufactured through screen-printing resistive paste on alumina substrates, these devices offer broad resistance ranges and cost-effective solutions for consumer electronics, automotive body electronics, and general industrial controls. AEC-Q200 qualified variants support automotive grade reliability requirements.
Thin Film Precision Resistors (TNPW, ACAS, LCS/MCS Series) Utilizing vacuum sputtering of nickel-chrome or tantalum nitride films, these resistors achieve TCR values as low as ±5ppm/℃ with tolerances to ±0.01%. The ACAS arrays provide exceptional ratio tracking for precision analog circuits, medical instrumentation, and audio equipment.
Bulk Metal Foil Resistors (S, VHP, Z, Y Series) Based on proprietary Bulk Metal® Foil technology, these devices exhibit virtually zero inductance (<0.08μH), negligible thermal EMF (<0.05μV/℃), and ESD withstand capability to 25kV. They serve as primary standards in metrology, aerospace power systems, and military communications where ultimate precision and stability are mandatory.
Wirewound Resistors (CW, WCR, C Series) Constructed by precision-winding resistance wire on ceramic cores, these products handle power levels from watts to kilowatts. The WCR water-cooled series achieves exceptional power density without external heatsinks, targeting precharge circuits, braking resistors, and industrial welding equipment.
Power Metal Strip Current Sense Resistors (WSL, WSR, WSN Series) Featuring solid metal strip construction, these devices offer ultra-low ohmic values (down to 0.0005Ω) with excellent thermal conductivity. Four-terminal Kelvin configurations eliminate lead resistance effects, making them ideal for battery management systems, motor drives, and on-board chargers in electric vehicles.
MELF Cylindrical Resistors Inherited from Vishay Draloric expertise, these cylindrical termination devices provide superior heat dissipation and pulse load capability compared to rectangular chips, widely used in automotive and telecommunications infrastructure.
High Voltage Specialized Resistors (CDMM, CRHV Series) The CDMM molded chip dividers address EV and high-voltage industrial applications with reinforced isolation, precise TCR tracking, and ratio tolerances optimized for battery management and DC fast charging systems.
Part Number Structure
Taking CRCW08052R20FKTABC as an example: CRCW identifies the thick film series; 0805 denotes the imperial package size; 2R20 indicates 2.2Ω resistance; F represents ±1% tolerance; K specifies TCR; T indicates tape-and-reel packaging; ABC covers special options.
