Description
CRCW1206100KFKEA-RES; 100k 0,25W ±1% THK FILM CHIP (1206) — BOLTON SKU 67792.
About the CRCW1206100KFKEA Resistor, 100k 1% 1206
The Vishay global part number resolves field by field: CRCW1206 identifies the D25/CRCW1206 e3 standard thick film chip resistor, 100K encodes the resistance using the R/K/M decimal convention (100 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 100K field is read as 100 thousand ohms; the larger case is the reason to choose this part over the same value in 0805. In the 1206 case the datasheet gives a rated dissipation of 0.25 W at 70 °C, a maximum operating voltage of 200 V AC RMS or DC and a one-minute insulation withstand of 300 V against the ambient. The operating temperature range is −55 °C to +155 °C with a permissible film temperature of 155 °C. The resistor is a laser-trimmed cermet film on high-grade alumina with a protective coating and pure matte tin over nickel plating, and the series is AEC-Q200 qualified.

Typical applications
Specifying 100 kΩ in the 1206 outline is normally about voltage and creepage rather than dissipation: the larger body carries a 200 V working rating and a 300 V one-minute insulation withstand, so it suits sensing and bleed networks hung off higher-voltage rails, discharge paths across bulk capacitors, and dividers feeding monitoring circuitry. The 0.25 W rating also gives more thermal margin where a fault could put the full rail across the part.
