Product Advantages
- 2W in a 2512 footprint — eliminates the need for parallel resistors, saving PCB area
- ±1% tolerance with ±400ppm/℃ TCR — stable across a wide temperature range
- 200V rating with surge withstand capability — absorbs transient energy up to 2× rated voltage
- Superior thermal dissipation — 96% alumina substrate improves heat conduction by ~40% vs. standard substrates
- Proven long-term stability — ΔR after 1000h aging is better than industry standard for thick film resistors
- SMT-compatible — standard 2512 land pattern, direct reel-to-reel assembly
Typical Applications
- Power supplies & DC-DC converters: secondary-side over-voltage sensing, snubber networks, current limiting
- Industrial control: current sense in servo motor drives, where 2W reduces PWM linearity error
- Automotive (BMS): shunt network for 400V battery systems
- Telecom: surge energy dissipation in 5G base station PA modules
- Consumer electronics: high-wattage (45W–100W) fast charger sensing and limiting
- Test & measurement: precision mid-low value dividers, load simulation
