SR20-0.005-1% - Caddock

SR20-0.005-1% 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 SR20-0.005-1% resistor ensures that the resistance value remains within the specified range over time, even under environmental stressors like temperature and humidity. This is critical for applications where stability is paramount.
• Can I use the SR20-0.005-1% in a high-frequency application?
  While the SR20-0.005-1% is not specifically designed for high-frequency applications, it can be used up to 100 kHz with minimal self-resonance. However, it's essential to consider the parasitic inductance and capacitance when designing the circuit.
• What is the recommended soldering temperature and time for the SR20-0.005-1%?
  Caddock recommends soldering the SR20-0.005-1% at a temperature of 260°C (500°F) for 3-5 seconds, with a maximum temperature of 280°C (536°F) for 1 second. This ensures reliable solder joints and minimizes thermal stress on the component.
• Is the SR20-0.005-1% suitable for use in a high-vibration environment?
  The SR20-0.005-1% is designed to withstand moderate vibration levels, but it's essential to consider the specific vibration profile and amplitude in your application. Caddock recommends consulting their application notes for vibration testing and guidance on securing the component.
