RH2512F75K0E04Z 2512 75K 2W
CRH2512F75K0E04Z belongs to Ever Ohms' CRH High-Power Thick Film Chip Resistor family, not UniOhm as sometimes confused. The naming breaks down as: CR = chip resistor, H = high-power / surge-rated, 2512 = imperial package (6.4 × 3.2 mm), F = ±1 %, 75K0 = 75 kΩ, E04Z = taping & RoHS code.

The CRH series pushes a standard 2512 from the usual 1 W up to 2 W by reinforcing the end electrodes (double-print Ag paste) and splitting the resistive element into two blocks for better heat spreading — that's the real differentiator vs. commodity 2512 parts.
Where 2512 75K 2W Gets Used
75 kΩ is a common value in feedback dividers and bleed circuits, so this part shows up in:
-
AC/DC & DC/DC feedback networks (e.g. TL431 or op-amp upper divider)
-
Inverter / motor-drive precharge & discharge paths — the 2 W rating and surge tolerance matter during power-up
-
Industrial sensor bias, MCU ADC dividers
-
Automotive (selected CRH parts are AEC-Q200 qualified — check the specific datasheet)
Why Pick This Over Alternatives?
Compared with a plain 2512 1 W resistor, you get double the rated power without moving to a 3720/4527 footprint. Compared with big-name 2 W parts (Yageo, Rohm, KOA), CRH sits in the mid-tier industrial sweet spot: TCR ±100 ppm, stable surge behavior, shorter lead times, and ~20–30 % lower cost than Japanese brands.
Brand Note
Ever Ohms (天二科技) is a Taiwan-based passive-component maker focused on thick/thin film chip resistors, arrays, and high-power lines. CRH is their answer to the Yageo/KOA 2 W segment and has gained traction in power-supply and industrial designs during the past few supply-cycle swings.
Sourcing Recommendations
For BOM integration or prototypes on the 2512 75K 2W spec:
-
Shenzhen Shunhai Technology Co., Ltd. (深圳市顺海科技有限公司) — Ever Ohms channel partner with decent CRH stock and BOM-matching service.
-
Huanian Mall (华年商城) — online inventory visibility; both the ±5 % version (CRH2512J75K0E04Z) and the ±1 % F-grade are listed, handy for price check and small-lot orders.
For volume builds, lock the MPQ (4000 pcs/reel) early — CRH lead times can stretch past 10 weeks when allocation tightens.
