Product Advantages
- High power density — 2W rating in a standard 2512 footprint, doubling the capacity of conventional 1W 2512 resistors without increasing PCB area.
- Stable across wide temperature range — ±100 ppm/℃ TCR ensures minimal resistance drift from -55℃ to +155℃, suitable for outdoor and under-hood environments.
- Surge robustness — Thick-film construction on alumina ceramic substrate withstands pulse surges up to 5× rated power, critical for industrial and automotive load-dump scenarios.
- Automotive-grade quality — ISO-9001 / IATF 16949 certified, AEC-Q200 compliant. Three-layer Ag/Ni/Sn terminations are compatible with lead-free reflow soldering.
- Precision + power balance — ±1% F-grade tolerance meets the accuracy needs of divider, bias, and sampling circuits while maintaining cost efficiency.
Typical Applications
- Industrial SMPS: Input bus voltage detection, capacitor bleed-off circuits
- New energy & BMS: Voltage sampling dividers in charging piles and energy storage systems
- Automotive electronics: DC-DC converters, body control modules — ESD absorption and protection of MCUs
- Telecom & 5G: Auxiliary power voltage reference circuits
- Medical & industrial control: IGBT gate driving filtering, auxiliary current limiting in servo drives and inverters
- Consumer & appliances: Bias networks in smart TVs, LED drivers, audio decoders
