CRH2512F75R0E04Z (2512 75R 2W) – Product Overview
Model Breakdown
CRH2512F75R0E04Z belongs to the CRH Series of EVER OHMS (Tian'er Technology), a Taiwan-based manufacturer specialized in chip resistors. The naming tells the story:
-
CRH – High-power thick-film chip resistor series
-
2512 – Package 6.3 × 3.2 mm
-
F – Tolerance ±1%
-
75R0 – Nominal resistance 75.0 Ω ("R" = decimal)
-
E04 – ±1% tolerance code
-
Z – Lot/batch traceability
In short: 2512 75R 2W, Tian'er CRH, 75 Ω ±1% 2 W.

The standout here is 2 W in a 2512 body – standard 2512 thick films usually stop at 1 W. CRH gets to 2 W via optimized ceramic substrate thermal path and sulfuration-resistant electrode plating; post-70°C load-life drift stays under 0.5%.
Applications
The 2512 75R 2W combination lands in places where you need medium resistance + real power dissipation:
-
Industrial PSU / motor drives – snubber, bleeder, dummy load; 2 W absorbs start-stop surges
-
DC-DC / SMPS feedback – where a 75 Ω leg needs to survive continuous dissipation
-
Automotive – CRH family is AEC-Q200 qualified; BMS, OBC, ECU usages are common
-
High-density consumer power – GaN fast-charger adapters, server PSUs where board space is tight but copper can help pull heat
Competitive Position
Within Tian'er's lineup, CRH2512F75R0E04Z sits in the "workhorse" tier – not the highest power (CRH also offers 3 W in larger footprints), but 75 Ω + 2 W + ±1% is a frequent BOM pick for BMS and industrial PSU design-in.
Market alternatives: Yageo RC 2512 2W (AEC-Q200, but lead-time volatile), Ellon EHP25 (thick-film sibling). Tian'er's angle is stable supply + sane pricing + spec positioning, which explains why many mainland PSU houses and auto Tier-2s run CRH as primary or secondary source.
Brand Note
EVER OHMS (Tian'er) – Taiwan-origin chip-resistor specialist with decades in the game. CRH is their high-power thick-film flag: 2 W in 2512, pushing 3 W in 2010/1812. Q1 2025 revenue hit RMB 351 M (+36.84% YoY), so supply-chain stability is arguably better than some bigger names when allocations tighten.
