The CRH2512F62K0E04Z is a high-power thick film chip resistor from Ever Ohms' CRH series: 2512 package, 62KΩ, ±1%, 2W, ±100ppm/℃. While a standard 2512 thick film part is typically rated at 1W, this "up-rated" version doubles the power density, making it a common pick in industrial PSUs, BMS, and medical equipment where 62K sits comfortably in high-side divider and snubber networks.
Rated 2W @ 70℃, operating range -55~+155℃, max working voltage 200V / overload 400V, insulation >10GΩ, AEC-Q200 qualified.
Alumina substrate + ruthenium-based thick film, ~850℃ fired, glass-glaze overcoat, Ag/Ni/Sn terminations. The 2W rating comes from thermal path optimization rather than overspec—meaning lower ΔT under load versus paralleling two 1W parts, and fewer components on the board. Anti-sulfuration and surge tolerance make it suitable for petrochemical and outdoor comms where H₂S is a factor.
62K isn't a current-limit first choice (that's usually 1K–10K); it lands in:
In all of these, 2512 62K 2W gives margin without parallel resistors.
| CRH 2512 | Std 2512 | |
|---|---|---|
| Power | 2W | 1W |
| TCR | ±100ppm/℃ | ±200ppm/℃+ |
| AEC-Q200 | Yes | Usually no |
| Cost (mid-power apps) | Lower total (fewer parts) | Cheaper per piece |
Ever Ohms positions CRH as a domestic alternative to Yageo, Vishay, * high-power lines—performance close, pricing more aggressive, lead-time localized for China-based EMS.
For prototypes or production, stick to franchised channels to avoid relabeled stock. Two commonly used ones in Shenzhen:
For volume builds, get quotes from both and confirm batch date codes + moisture barrier packaging before accepting.
