CRCW080511K5FKEA-RES; 11k5 0,125W ±1% THK FILM CHIP D12 (0805) — BOLTON SKU 67788.
About the CRCW080511K5FKEA Resistor, 11.5k 1% 0805
The Vishay global part number resolves field by field: CRCW0805 identifies the D12/CRCW0805 e3 standard thick film chip resistor, 11K5 encodes the resistance using the R/K/M decimal convention (11.5 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 11K5 field encodes 11.5 thousand ohms, a value that exists only on the E96 series and so is only offered in the ±1% grade. 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. The element is a cermet film on alumina, laser trimmed and overcoated, with pure matte tin over nickel terminations, and the series holds AEC-Q200 qualification.

Typical applications
An off-decade E96 value like 11.5 kΩ is specified deliberately, almost always to land a divider ratio or a regulator feedback network on an exact output rather than to limit current. Typical placements are the feedback string of an adjustable switching or linear regulator, a reference scaling network, or a gain leg where the design calls for a computed ratio. Pairing it with a matching ±100 ppm/K partner keeps the ratio drift bounded across the −55 °C to +155 °C range.
