CRH2512F47R0E04Z 2512 High Power Thick Film Chip Resistor with 47Ω 2W and ±1% Tolerance

CRH2512F47R0E04Z is a high-power thick film chip resistor from EVER OHMS (Taiwan), belonging to the CRH series. It features a 2512 case size (6.35×3.20mm metric), 47Ω nominal resistance, 2W rated power at 70℃, ±1% tolerance, and ±100ppm/℃ TCR. Compared to a standard 1W 2512 chip resistor, the CRH version doubles the power handling capability in the same footprint, making it suitable for switching power supplies, industrial controls, LED drivers, and telecom equipment.

Within EVER OHMS' official CRH product matrix, the 2512 / 2W configuration covers a resistance range from 1Ω up to 1MΩ. The 47Ω value is among the most frequently specified in power-critical designs.

In a typical 24V industrial or communication power system, a 47Ω resistor dissipates approximately 1.1W at 0.7A load current. A standard 1W 2512 leaves insufficient margin under surge and high-temperature conditions. The 2512 47R 2W resistor addresses this gap:

• Single-device replacement: One 2W 2512 can replace two 1W 2512 parts in parallel — saving PCB area and reducing solder joint failure risk

• Pulse withstand: The CRH series uses a three-layer electrode structure (Ni barrier + Sn outer layer + glass glaze protection) with laser-trimmed resistance, capable of enduring short-term overload and high pulse currents

• Thermal stability: ±100ppm/℃ TCR ensures minimal drift across the full -55℃~+155℃ operating range

• Process compatibility: Withstands reflow and wave soldering at 260±5℃ peak for up to 10 seconds

⚠️ For ambient temperatures above 85℃, derate power to ≤1.6W and reserve at least 10mm² of copper pour around the pads for heat dissipation.

• SMPS & DC-DC converters: Feedback network, primary-side current limiting

• LED driving circuits: Load matching, constant-current source sensing

• Industrial drives: Braking resistor substitution, power detection

• Home appliance control boards: Over-current protection in inverter modules

• Telecom power modules: Transient voltage absorption, signal division

• EV BMS: Cell balancing loops, charge/discharge current limiting
