RL622-220K-RC - Bourns

RL622-220K-RC Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for optimal performance?
  Bourns recommends a symmetrical layout with a central pad for the inductor, and a minimum of 2-3 vias for thermal relief. A recommended land pattern is available in the Bourns application note AN-13.
• How does the inductor behave under high-frequency switching conditions?
  The RL622-220K-RC is designed to handle high-frequency switching up to 1 MHz. However, it's essential to consider the skin effect, proximity effect, and core losses when operating at high frequencies. Consult Bourns' application notes for guidance on high-frequency design considerations.
• What is the maximum allowable current for this inductor?
  While the datasheet specifies a rated current of 2.2 A, the maximum allowable current depends on the operating temperature and PCB design. As a general guideline, do not exceed 80% of the rated current to ensure reliable operation.
• Can I use this inductor in a high-temperature environment?
  The RL622-220K-RC is rated for operation up to 125°C. However, derating is necessary for temperatures above 85°C. Consult the datasheet for temperature derating curves and consider using a higher temperature-rated inductor if your application exceeds 125°C.
• How do I ensure the inductor is properly soldered and secured to the PCB?
  Follow the recommended soldering profile and ensure the inductor is securely attached to the PCB using a suitable adhesive or mechanical fastening method. Avoid excessive soldering temperatures and ensure the inductor is not subjected to mechanical stress or vibration.
