CRL0603-FW-R620ELF - Bourns

CRL0603-FW-R620ELF Frequently Asked Questions (FAQs)

• What is the recommended land pattern for this chip resistor?
  The recommended land pattern for the CRL0603-FW-R620ELF can be found in the Bourns Application Note S-308, which provides guidelines for PCB layout and assembly.
• How do I handle the resistor in terms of soldering and rework?
  Bourns recommends following the J-STD-020 standard for soldering and rework of surface mount devices. Additionally, the company provides a Soldering and Rework Application Note (S-311) that provides specific guidelines for their chip resistors.
• What is the moisture sensitivity level (MSL) of this resistor?
  The CRL0603-FW-R620ELF has an MSL rating of 1, which means it can be exposed to a maximum of 30°C/85% RH for 168 hours without being baked prior to reflow soldering.
• Can I use this resistor in a high-frequency application?
  While the CRL0603-FW-R620ELF is a general-purpose chip resistor, it may not be suitable for high-frequency applications due to its construction and materials. For high-frequency applications, Bourns offers specialized chip resistors with lower inductance and capacitance, such as the CHV series.
• How do I determine the power rating of this resistor at elevated temperatures?
  The power rating of the CRL0603-FW-R620ELF decreases as the operating temperature increases. Bourns provides a derating curve in the datasheet that shows the maximum power rating at different temperatures. Engineers can use this curve to determine the power rating at their specific operating temperature.
