The 104PC wirewound precision resistor series from Riedon offers resistance values between 700kΩ and 1MΩ (lower resistances available upon request) at a power rating of 0.5W, tolerances as low as ±0.005% and a standard TCR of ±10 ppm/°C (wide TCR range, including Balco and Platinum wire for high TCR, available upon request). These resistors utilise a traditional design for through-hole circuit board mounting, while offering a number of custom features. The 104PC series resistors are all 100% acceptance tested and traceable to NIST, and offer long term stability of 100ppm/year (20ppm/year version available). Matched resistance sets to ±0.001% and ±0.5ppm/°C are also available.
