VPG Foil Resistors

VPG Foil Resistors has been a leader in manufacturing precision resistors using their unique Bulk Metal® Foil technology since 1978, offering exceptional performance with a typical temperature coefficient of resistance (TCR) of 0.14ppm/℃, a remarkable tolerance of ±0.005%, and impressive long-term stability of just 5ppm per year, or 10ppm over three years.

Ultra High-Precision Surface Mount Resistors

- Temperature coefficient of resistance (TCR): 0.05 ppm/°C typical (0°C to +60°C) by New Generation Z-Foil Technology
- 0.2 ppm/°C typical (–55°C to +125°C, +25°C ref.)
- Resistance tolerance: to ±0.01%
- Power coefficient “∆R due to self heating”: 5 ppm at rated power (typical)
- Power rating: to 200 mW (MPP) and 250 mW (MQP) at +70°C
- Load life stability: to ±0.005% at 70°C, 2000h at rated power (typical)
- Not restricted to standard values, we can supply specific “as required” values at no extra cost (e.g., 1K2345 vs. 1K)
