CRH2512F523RE04Z (2512 523R 2W) High-Power Thick Film Chip Resistor – Full Analysis
1. Part Number Decoding
CRH2512F523RE04Z follows EVER OHMS' standard naming:
-
CRH – High-power thick film series (vs. standard CR)
-
2512 – Imperial package, metric 6432 (6.4 × 3.2 mm)
-
F – Tolerance ±1% (J = ±5%, B = ±0.1%)
-
523R – 523 Ω ("R" as decimal)
-
E04 – Internal code, 2W rating for 2512 in CRH family
-
Z – RoHS-compliant tape & reel
In short: a 2512 523R 2W ±1% high-power thick film resistor from EVER OHMS' CRH line.

The 2W rating in a 2512 body comes from optimized thick-film paste, multi-layer terminations, and Al₂O₃ substrate sintered at 850 ℃—about 50% higher power density than a standard 2512 (1W) part.
3. Typical Applications
The 2512 523R 2W combination fits where power is just over a normal 2512 but a 2725 or shunt is overkill:
-
DCDC feedback divider, auxiliary dummy load
-
PLC analog input divider, 4–20 mA sense bypass
-
Motor drive gate-board bleeder / voltage balance
-
LED driver current-sense leg (523R gives comfortable margin at 2W)
-
BMS pre-charge / cell balance limiter
One 2512 523R 2W can replace two 1206 1W parts in parallel—saving PCB area and pick-and-place cycles.
4. Advantages vs. Standard CR Series
-
2W vs 1W in same 2512 footprint
-
TCR ±100 vs ±200 ppm/℃ on standard CR
-
Anti-sulfuration terminals for industrial atmospheres
-
Cost well below 2725 or alloy shunts
5. Market Position & Brand
EVER OHMS (天二) is a leading domestic Chinese thick-film chip resistor brand, positioned as a direct alternative to YAGEO AC and Fenghua RS high-power lines. The CRH family targets industrial PSU, motor drives, LED drivers, and automotive-peripheral boards. 2512 523R 2W sits in the mid-value, mid-high-power sweet spot—high volume, widely second-sourced.
Cross-ref: YAGEO AC2512FK-07523RL, Fenghua RS-25K5230FT. Watch TCR and termination differences when substituting in industrial designs.
6. Distribution
Shenzhen Shunhai Technology (深圳市顺海科技有限公司) is an authorized EVER OHMS distributor with CRH 2512 523R 2W stock across F/J tolerance grades—good for volume inquiry and substitution support. For small-lot sampling and live inventory checks, Huanian Mall (华年商城) also carries the full EVER OHMS CRH lineup with clear reel/spec labeling.
