CRH2512F750RE04Z: A Full Breakdown of This 2512 750R 2W High-Power Thick-Film Chip Resistor
Part Number Decoding
CRH2512F750RE04Z follows Ever Ohms' CRH series naming:
-
CRH = High-power thick-film chip resistor family (EVER OHMS)
-
2512 = Imperial footprint, 6.35 × 3.20 mm
-
F = Tolerance ±1% (J would be ±5%)
-
750R = 750Ω nominal
-
E04Z = Internal spec code (±100 ppm/°C, lead-free)
So this is a 2512 750R 2W part: 2 W rated power in a 2512 body, ±1%, ±100 ppm/°C, AEC-Q200 qualified.

Why 2W in 2512 Matters
Standard 2512 thick-film resistors typically cap at 1 W; some "high-power" versions reach 1.5 W. The CRH series pushes it to 2W in the same footprint via:
-
95% Al₂O₃ ceramic substrate + ruthenium-based thick-film paste, sintered at 850℃
-
Three-layer terminations (Ag/Ni/Sn) for anti-sulfidation and solderability
-
AEC-Q200 qualification, <0.5% drift after 1000 h at 70℃
For engineers, that means either one fewer paralleled resistor or more derating headroom — the real selling point of this 2512 750R 2W spec.
Typical Applications
750Ω sits in the mid-range; paired with 2W it lands in:
-
Automotive: BMS voltage sensing dividers, OBC, LED drivers (AEC-Q200 is the gatekeeper here)
-
Industrial: SMPS feedback networks, soft-start current limit, inverter snubber circuits
-
New Energy: PV inverter balancing, ESS PCS current sense
-
Appliances: Water heaters, microwaves, motor control loads
