Description
CRCW08052R70FKEA-RES; 2R7 0,125W ±1% THK FILM CHIP (0805) — BOLTON SKU 67789.
About the CRCW08052R70FKEA Resistor, 2.7 ohm 1% 0805
The Vishay global part number resolves field by field: CRCW0805 identifies the D12/CRCW0805 e3 standard thick film chip resistor, 2R70 encodes the resistance using the R/K/M decimal convention (2.70 Ω), 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 2R70 field uses R as the decimal point, giving 2.70 ohms. 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. It is made by laser trimming a cermet film on an alumina substrate, protected by a coating and finished with pure matte tin over nickel terminations, and is AEC-Q200 qualified.

Typical applications
Low single-digit ohm values are used for damping and limiting rather than for dividing: series gate resistors that slow a MOSFET edge, snubber legs across switching nodes, series damping on clock and supply feeds, and modest inrush limiting into small local capacitance. Because current, not voltage, is the limiting factor at 2.70 Ω, the 0.125 W rating of the 0805 case sets the working ceiling and should be checked against the actual peak current rather than the average. The ±1% tolerance is useful where the damping value was calculated rather than chosen by trial.
