Vishay CRCW0402634RFKED 634 ohm 0402 SMD Resistors 75 PCS
Full Description & History
Genuine Vishay Dale CRCW0402634RFKED thick-film surface-mount chip resistors, supplied as one lot containing 75 pieces from original distributor-labeled electronic component stock.
These miniature 0402 SMD resistors feature a nominal resistance of 634 ohm, ±1% tolerance, and a standard power rating of 0.063W (1/16W).
Part of Vishay's D/CRCW e3 series, these precision-tolerance resistors are designed for compact electronic assemblies requiring dependable fixed resistance and high component density.
The CRCW0402634RFKED features automotive AEC-Q200 qualification, a temperature coefficient of ±100 ppm/°C, and an operating temperature range of -55°C to +155°C.
Suitable applications include voltage dividers, signal conditioning, transistor bias networks, current-limiting circuits, feedback networks, industrial control boards, instrumentation, communications electronics, automotive circuitry, and component-level PCB repair.
The 0402 (1005 Metric) package measures approximately 1.0 × 0.5 mm and is designed for automated surface-mount assembly.
The original distributor label identifies Vishay as the manufacturer, Israel as the country of origin, and carries date code 1638.
Lot Size: 75 Pieces
HISTORICAL BACKGROUND:
Vishay Intertechnology was founded in 1962 by Felix Zandman and developed into one of the world's major manufacturers of passive electronic components and discrete semiconductors.
The Vishay Dale product family includes an extensive range of fixed resistors, precision resistors, power resistors, and specialty components used in industrial, automotive, communications, and electronic measurement equipment.
Thick-film resistor technology became an important manufacturing method for producing compact and economical fixed-resistance components. These resistors use a resistive film deposited onto a ceramic substrate, allowing reliable electrical performance in miniature packages.
As electronic circuit boards became smaller and more densely populated, surface-mount chip resistors increasingly replaced larger through-hole components in many applications.
Vishay's D/CRCW e3 series was developed for general-purpose and automotive electronic applications, offering a broad selection of resistance values, tolerance options, and miniature SMD package sizes.
The CRCW0402634RFKED provides 634 ohm nominal resistance with ±1% tolerance in the compact 0402 package. Its AEC-Q200 qualification supports use in appropriately designed automotive electronic systems.
The original distributor packaging carries date code 1638, conventionally corresponding to the thirty-eighth production week of 2016.
The packaging identifies Israel as the country of origin, reflecting Vishay's historical manufacturing presence in that country.
