SRP1245A-4R7M Frequently Asked Questions (FAQs)

  • The recommended land pattern for the SRP1245A-4R7M can be found in the Bourns application note AN204, which provides guidelines for PCB layout and land pattern design.
  • The power rating of the SRP1245A-4R7M is 1/4 watt. To ensure reliable operation, the component should be derated based on the ambient temperature and the desired reliability level. A general guideline is to derate the power rating by 50% for every 25°C above 25°C.
  • The tolerance of the SRP1245A-4R7M is ±5%. This means that the actual resistance value can vary by up to 5% from the nominal value of 4.7 ohms.
  • The SRP1245A-4R7M is a general-purpose resistor and may not be suitable for high-frequency applications. For high-frequency applications, it is recommended to use a resistor with a higher frequency rating, such as the Bourns CHV series.
  • To ensure the reliability of the SRP1245A-4R7M, follow proper PCB design and assembly guidelines, ensure proper voltage and current ratings, and consider environmental factors such as temperature and humidity.
