CRH2512F56K0E04Z (2512 56K 2W) High-Power Thick Film Chip Resistor — Full Analysis
1. Part Number Breakdown
CRH2512F56K0E04Z follows Ever Ohms CRH series naming:
-
CRH — High-power thick film chip resistor family
-
2512 — 6.3×3.2mm footprint
-
F — Tolerance ±1%
-
56K0 — 56 kΩ nominal
-
E04Z — Tape & reel / batch code
Key specs: 2512, 56K, 2W, ±1%, ±100 ppm/°C, 200 V rated / 3000 V overload, –55 to +155 °C.
2. Key Characteristics
The standout is power density. A standard 2512 thick-film part is usually 1 W; the CRH pushes 2512 56K 2W to 2 W continuous in the same footprint via thicker terminations and optimized paste/thermal path.
-
56 kΩ in the mid-high range, ±1% with ±100 ppm/°C suits divider / discharge / sense networks
-
200 V rating + 3000 V surge withstand for industrial & appliance transients
-
Sn-Ni plating, anti-sulfuration, reflow-friendly
3. Typical Applications
2512 56K 2W lands in:
-
SMPS: auxiliary divider, startup resistor, X-cap discharge (56 k/2 W common on 220 V AC side)
-
Appliance control: AC / fridge mains interface
-
Industrial & metering: energy meter shunt, navigation, comms bias
-
Automotive & medical: –55~155 °C covers in-cabin and UV-disinfection loads
4. Advantages & Market Positioning
Against YAGEO / UniOhm 2512 2 W equivalents:
-
Full 2 W@2512 without stepping up to 3720
-
Balanced TCR + surge rating (±100 ppm / 3000 V)
-
Cost edge vs. tier-1 TW brands, positioned for industrial / appliance / mid-range PSU BOM cost-down
5. Brand Note
Ever Ohms (天二) — TW-based passive specialist, CRH high-power thick film is a volume line in its chip-resistor portfolio, distributed in CN mainly through authorized agents and spot-platforms.
