CRH2512F680RE04Z High-Power Thick Film Chip Resistor with 2W Rated Power, 680

CRH2512F680RE04Z follows the unified coding standard of EVER OHMS. CRH stands for high-power thick film chip resistor series; 2512 is standard imperial package with dimension 6.35mm×3.2mm×0.55mm; F means resistance tolerance ±1%; 680R refers to nominal resistance 680 ohms; E04Z represents 7-inch lead-free tape & reel packing for automatic SMT production lines. The core identification 2512 680R 2W indicates its 2W rated power, a mainstream selection for medium-high voltage voltage divider and power discharge circuits.

This 2512 680R 2W thick film resistor adopts high thermal conductivity 95% alumina ceramic substrate with sintered ruthenium-based resistance paste, covered by compact glass glaze protective coating. Under 70℃ ambient temperature, its rated power remains steady at 2W, maximum working voltage reaches 250V, and transient overload voltage hits 3000V with outstanding surge resistance. Its TCR is ±100ppm/℃, operating temperature range from -55℃ to +155℃, ensuring tiny resistance drift under temperature cycling. Triple-layer nickel-tin terminal electrodes support lead-free soldering at peak 260℃. The component complies with RoHS and REACH standards, lead & cadmium free without restricted SVHC substances, with excellent anti-sulfuration and moisture-proof performance for long-term operation in humid industrial and semi-closed automotive environments.

The matching resistance and power of 2512 680R 2W fit various power electronic circuits:

1. Switching power supply & fast charger modules: Start-up resistor, dummy load and voltage divider to absorb surge current during power-up without overheating failure under 2W power margin;
2. Industrial control equipment: PLC input voltage divider, snubber circuit for servo drivers and IGBT absorption loop of inverters to suppress instantaneous voltage spikes from motor startup;
3. High-power LED lighting drivers: Bleeder and current-limiting element for non-isolated constant-current circuits, suitable for outdoor street lamps and industrial floodlights with long continuous operation;
4. Automotive & new energy auxiliary power: Infotainment system and low-voltage BMS balancing divider, qualified by IATF16949 production standard for wide-temperature vehicle working conditions;
5. Measuring instruments & communication power supplies: Benchmark voltage divider for 5G auxiliary power and test equipment, ±1% tolerance guarantees accurate sampling without offset.

Compared with ordinary thick film resistors in the same package, CRH2512F680RE04Z 2512 680R 2W owns four major strengths. First, superior power density, delivering 2W rated power within standard 2512 size to save PCB space for miniaturized device design. Second, consistent resistance batch performance, ±1% tolerance plus low TCR minimize discrete error without secondary calibration. Third, long service life, glass glaze coating blocks sulfur vapor and moisture to reduce maintenance rate of field equipment. Fourth, complete production compatibility, standard reel packing fits all mainstream SMT machines with stable stock lead time. resistors in the market usually have fake power rating and burn out under full load. Authorized distributors are recommended for authentic purchasing.
