RFS1317-474KL - COILCRAFT

RFS1317-474KL Frequently Asked Questions (FAQs)

• What is the recommended land pattern for the RFS1317-474KL?
  Coilcraft recommends a land pattern with a pad size of 3.3 mm x 2.5 mm, with a non-solder mask defined (NSMD) pad shape. The recommended land pattern is available on Coilcraft's website.
• Can I use the RFS1317-474KL in a high-temperature environment?
  The RFS1317-474KL is rated for operation up to 125°C. However, the inductor's performance may degrade at high temperatures. Coilcraft recommends derating the inductor's current rating by 1.5% for every degree above 80°C.
• How do I handle the RFS1317-474KL's sensitivity to mechanical stress?
  The RFS1317-474KL is sensitive to mechanical stress, which can cause the inductor's core to crack or the windings to break. To minimize stress, avoid bending or flexing the leads, and use a stress-relieving pad or a strain-relief feature in the PCB design.
• What is the RFS1317-474KL's moisture sensitivity level (MSL)?
  The RFS1317-474KL has an MSL rating of 1, which means it can withstand unlimited time at room temperature and humidity without being exposed to moisture. However, it's still recommended to follow proper handling and storage procedures to prevent moisture absorption.
• Can I use the RFS1317-474KL in a high-vibration environment?
  The RFS1317-474KL is designed to withstand moderate vibration levels. However, excessive vibration can cause the inductor's performance to degrade or even fail. Coilcraft recommends evaluating the inductor's performance in the specific vibration environment to ensure reliability.
