CRH2512F27K0E04Z 2512 27kΩ 2W High Power Thick Film Chip Resistor with ±1% Tolerance

The CRH2512F27K0E04Z is a high-power thick film chip resistor from EVER OHMS' CRH series, featuring a standard 2512 package, a nominal resistance of 27kΩ, a rated power of 2W, and a tolerance of ±1%. This component serves as a widely adopted choice in industrial control, telecom power supplies, and new energy equipment, where its high power density and stable resistance characteristics meet the demands of medium-power circuit designs.

EVER OHMS has optimized the ceramic substrate and resistive paste formulation in the CRH series to achieve elevated power ratings within standard package dimensions. The 2512 package corresponds to a metric size of 6.4mm × 3.2mm, providing sufficient heat dissipation area for a 2W rating while maintaining full compatibility with surface-mount assembly processes.

The CRH2512F27K0E04Z part number conveys complete product information:

• CRH: High-power thick film chip resistor series

• 2512: Imperial package code, equivalent to metric 6432 (6.4mm × 3.2mm)

• F: Tolerance code indicating ±1%

• 27K0: Resistance code representing 27kΩ (27,000Ω), where "K" denotes kilo-ohm and "0" confirms no significant digit after the decimal

• E04: Packaging and process code

• Z: RoHS environmental compliance marker

Compared with conventional 2512 thick film resistors, the CRH series increases power handling from 1W to 2W through structural optimization and enhanced thermal performance.

The ±100ppm/℃ TCR keeps resistance drift within acceptable limits across the rated temperature range, satisfying the stability requirements of most industrial circuits. The 2W rating allows this device to replace certain traditional through-hole resistors, supporting miniaturization efforts.

High Power Density: Delivering 2W within a 2512 footprint, this resistor offers superior power density compared to standard thick film alternatives, reducing PCB real estate in high-density layouts.

Wide Temperature Operation: The -55℃ to +155℃ range accommodates industrial environments, including outdoor telecom gear, automotive peripheral circuits, and industrial automation systems.

SMT Compatibility: The 2512 package suits mainstream pick-and-place and reflow processes. The three-layer termination (Ag/Ni/Sn) has been validated for soldering reliability in volume production.

Resistance Stability: Thick film processing combined with laser trimming ensures the 27kΩ nominal value remains within ±1% tolerance across production lots, minimizing matching effort during circuit calibration.

Industrial Power Modules: In feedback divider networks of switching power supplies, the 27kΩ value and 2W rating allow direct use for primary or secondary voltage sensing without paralleling multiple devices.

Motor Drive Circuits: Within snubber and RC absorption networks of inverters and servo drives, the 2512 27K 2W resistor withstands periodic pulse power and suppresses switching noise.

New Energy Equipment: Photovoltaic inverters, BMS balancing circuits in energy storage systems, and EV charger control boards demand wide temperature ranges and power margins, requirements that the CRH2512F27K0E04Z satisfies.

Telecom Infrastructure: Base station power units and PoE equipment rely on long-term stability for current limiting and voltage division nodes, where this component's TCR performance fits design targets.

When applying the CRH2512F27K0E04Z in circuit designs, engineers should apply appropriate power derating—typically 60% to 70% of the rated value—to enhance long-term reliability. PCB layout should maximize copper pad area to reduce thermal resistance.
