CRH2512F33R0E04Z 33Ω 2W High Power Thick Film Chip Resistor in 2512 Package by EVER OHMS
The CRH2512F33R0E04Z is a high-power thick film chip resistor from EVER OHMS (Taiwan), belonging to the CRH series that doubles the power rating within a standard footprint. This 2512 33R 2W resistor is widely specified in power supply modules, industrial control boards, and automotive BMS designs.

Standard 2512 thick film resistors are rated at 1W. The CRH series achieves 2W through:
- Thick ruthenium-oxide resistive layer (~100μm) enabling power density up to 70 W/cm²
- Three-layer electrode (Ni barrier + Sn outer layer + glass protection) for surge withstand
- 96% alumina ceramic substrate with ~40% better thermal conductivity than conventional substrates
At 33Ω, a 24V industrial rail delivering 0.7A dissipates ~1.6W — already exceeding the 1W version's safe limit. The 2512 33R 2W resistor closes this margin gap with a single component, replacing two parallel 1W 2512 parts.
- SMPS & DC-DC converters: RC snubber, buffer, dummy load
- Industrial drives: Current sensing, current limiting
- Automotive BMS: Cell balancing, charge/discharge limiting
- Home appliance control boards: Over-current protection for inverter modules
- Telecom power modules: Transient absorption, signal division
- Consumer fast chargers: Secondary-side sampling in compact 45W PD designs
⚠️ For ambient above 85℃, derate to ≤1.6W and reserve ≥10mm² copper pour around pads.
