CRH2512F24R9E04Z 2512 Chip Resistor 24.9Ω 2W High Power Thick Film with ±1% Tolerance
The CRH2512F24R9E04Z is a 2512 24.9R 2W chip resistor from Ever Ohms (EVER OHMS) CRH high-power thick film series. It doubles the power density of conventional 2512 thick film resistors by delivering 2W in the same footprint, making it a popular choice for switching power supplies, automotive electronics, industrial control, and new energy applications.

- Resistance: 24.9Ω ±1%
- Rated Power: 2W (measured at 70℃ ambient)
- TCR: ±100ppm/℃ over -55℃ ~ +155℃
- Max Working Voltage: 200V
- Overload Voltage: 400V
- Insulation Resistance: >10GΩ
- Thermal Resistance: 75℃/W (typical)
- Power Derating: Above 70℃, derate at 12.5mW/℃; reaches 0W at 155℃
- Substrate: 96% alumina ceramic
- Resistive Element: Ruthenium-based thick film paste, fired at high temperature
- Termination: 3-layer (Ag/Pd inner, Ni barrier, pure Sn outer)
- Power Supplies & DC-DC: Secondary-side feedback dividers, soft-start current limiting, snubber circuits
- Automotive: OBC, BMS cell balancing (AEC-Q200 qualified)
- Industrial: Inverters, servo drives, PLC input dividers, motor back-EMF absorption
- Telecom & New Energy: 5G base station PSU, PV inverter, energy storage PMU
- Consumer: LED drivers, fast charger modules
- Double Power Density — 2W in a 2512 footprint eliminates the need for parallel resistors.
- Low TCR — ±100ppm/℃ keeps resistance stable under full load and wide temperature swings.
- Wide Operating Range — -55℃ to +155℃ covers industrial and automotive grade requirements.
- Cost-Effective — Thick film process costs 40~60% less than thin film, while meeting IATF 16949 and AEC-Q200.
- Long-Term Stability — Enhanced film adhesion and anti-sulfidation treatment for long-life deployments.
