SR20-0.20-1% - Caddock

SR20-0.20-1% Frequently Asked Questions (FAQs)

• What is the recommended power derating for high-temperature applications?
  Caddock recommends derating the power by 1% for every 1°C above 25°C to ensure reliable operation. For example, at 50°C, the power rating would be 80% of the maximum rating.
• How does the resistor's tolerance affect its long-term stability?
  The 1% tolerance of the SR20-0.20-1% resistor ensures that the resistance value remains within the specified range over time, even under varying environmental conditions. This is particularly important in precision circuits where small changes in resistance can affect overall performance.
• Can I use the SR20-0.20-1% in a high-humidity environment?
  While the SR20-0.20-1% is designed to operate in a wide range of environmental conditions, it's still important to follow proper humidity protection measures to prevent moisture ingress. Caddock recommends using a conformal coating or potting the resistor in a humid environment.
• What is the recommended soldering temperature and time for the SR20-0.20-1%?
  Caddock recommends soldering the SR20-0.20-1% at a temperature of 260°C (500°F) for 3-5 seconds, with a maximum soldering time of 10 seconds. Exceeding these limits can damage the resistor or affect its performance.
• Is the SR20-0.20-1% suitable for high-frequency applications?
  The SR20-0.20-1% is designed for general-purpose applications and may not be suitable for high-frequency applications above 100 kHz. For high-frequency applications, Caddock recommends using their high-frequency resistor series, such as the HF Series.
