CRH2512F27K0E04Z Ever Ohms Resistor - Technical Analysis
Product Overview
The CRH2512F27K0E04Z is a standard high-power thick film chip resistor from EVER OHMS (Tian Er Technology), part of the CRH series. EVER OHMS, established in 1988 in Kaohsiung, Taiwan, is a specialized resistor manufacturer with nearly four decades of industry experience. The company obtained IATF16949 automotive certification in 2010, with products compliant with AEC-Q200 standards.
This model features a 2512 package (metric 6432), 27kΩ nominal resistance, 2W rated power, ±1% tolerance, and ±100ppm/℃ temperature coefficient. The complete part number CRH2512F27K0E04Z follows EVER OHMS' coding scheme: CRH = series (high-power thick film), 2512 = package size, F = tolerance class (±1%), 27K0 = 27kΩ resistance value, E04Z = packaging and production batch information.

Key advantages of CRH2512F27K0E04Z:
-
High power density: 2W power rating in a 2512 package, suitable for space-constrained applications requiring significant power handling
-
Wide temperature range: -55℃ to +155℃, covering cold environments to high-temperature industrial equipment
-
Environmental compliance: RoHS compliant (2011/65/EU) and REACH SVHC-free
-
Tape & reel packaging: 4000 pieces per reel, compatible with automated SMT assembly lines
Applications
With its 2W power rating and 2512 package, CRH2512F27K0E04Z is widely used in:
-
Power management: Switching power supplies, DC-DC converters
-
Industrial controls: Inverters, PLCs, industrial voltage regulators
-
Automotive electronics: BMS, ECU sampling and protection circuits
-
Consumer electronics: Fast chargers, computer motherboards
-
Medical equipment: Spectrophotometers, autoclaves
-
Smart appliances: Refrigerators, dehumidifiers, smart drying racks
Selection Considerations
-
Power derating: The 2W rating is based on 70℃ ambient temperature. For operating temperatures above 70℃, derate according to the specification curve
-
Operating voltage: Maximum 200V; actual use must satisfy both P = V²/R and voltage limits
-
Tolerance matching: ±1% suits most industrial and consumer applications; for higher precision (±0.1%, ±0.5%), consider EVER OHMS precision thin film series
-
Alternatives: TE Connectivity CRGH2512 series can be evaluated as a substitute
