CRH2512F330RE04Z High-Power Thick Film Chip Resistor with 330Ω Resistance, 2W

The CRH2512F330RE04Z​ is a representative part of the CRH series high-power thick film chip resistors from EVER OHMS Technology Co., Ltd. This 2512 330R 2W resistor​ combines a standard 2512 footprint (6.30 × 3.20 mm) with 330Ω resistance, ±1% tolerance, and 2W rated power at 70℃, making it suitable for space-constrained, high-power-density applications.

While conventional 2512 thick film resistors are typically rated at 1W, the CRH2512F330RE04Z 2512 330R 2W resistor​ doubles the power density through:

1. Upgraded thick film paste​ – Ru-based oxide paste sintered at 850℃, thicker resistive layer with shorter thermal path;
2. Three-layer termination​ – Ag/Ni/Sn plating improves both thermal conductivity and solder joint reliability;
3. Alumina ceramic substrate​ – Superior thermal conductivity vs. standard FR-4, delivering lower temperature rise.

At 330Ω, the theoretical voltage corresponding to 2W is about 25.7V (√(P×R)), far below the 200V rating—providing generous voltage headroom. Even at 85℃ ambient, derating to 60% of rated power (≤1.2W) keeps resistance drift well under control.

The 2512 330R 2W resistor​ finds its primary use in:

• Power supplies & DC-DC converters: feedback network dividers, soft-start current limiting, RCD snubber buffers
• Industrial control: gate drive resistors and bleed circuits in VFDs and servo drives
• Communication equipment: base station power modules, fax machines, mobile phone mainboards
• Computers & peripherals: server and mainboard power management
• Home appliances & consumer electronics: air conditioners, refrigerators, audio devices, tablets
• Measuring instruments: electric meters, navigation equipment
• New energy & automotive: BMS voltage balancing, on-board charger (OBC) bus voltage sensing
