Description
CRCW08053K40FKEA-RES; 3k40 0,125W ±1% THK FILM CHIP (0805) — BOLTON SKU 67772.
About the CRCW08053K40FKEA Resistor, 3.4k 1% 0805
The Vishay global part number resolves field by field: CRCW0805 identifies the D12/CRCW0805 e3 standard thick film chip resistor, 3K40 encodes the resistance using the R/K/M decimal convention (3.40 kΩ), F sets the resistance tolerance at ±1%, K sets the temperature coefficient of resistance at ±100 ppm/K, and EA is the lead-free packaging code for a 5,000-piece 180 mm (7-inch) reel. The 3K40 field places the part on the E96 series used for ±1% values. In the 0805 case the datasheet gives a rated dissipation of 0.125 W at 70 °C, a maximum operating voltage of 150 V AC RMS or DC and a one-minute insulation withstand of 200 V against the ambient. The operating temperature range is −55 °C to +155 °C with a permissible film temperature of 155 °C. Construction is a cermet film with a glass overglaze on a high-grade alumina substrate, laser trimmed to value and finished with pure matte tin over nickel terminations; the series is AEC-Q200 qualified.

Typical applications
A 3.40 kΩ E96 value at ±1% is chosen where a ratio has to be held rather than simply a current limited, so it appears in feedback and reference dividers, gain-setting legs around operational amplifiers and instrumentation stages, and biasing networks in analogue front ends. The 0805 case gives useful headroom at 0.125 W for the modest dissipation such networks produce and is large enough to inspect and rework by hand. The 150 V working-voltage ceiling covers low-voltage signal and control circuitry comfortably.
