Notes

*SRF approximate nominal values for design info only
Suffix "M" for 20% tolerance, Suffis "K" for 10% tolerance, Suffix "J" for 5% tolerance, Suffix "H" for 3% tolerance, Suffix "G" for 2% tolerance or Suffix "F" for 1% tolerance
Custom designs are available to meet your specific requirements; please contact factory

Operating Temperature Range: -55°C to +125°C

Current rating is based on a 35°C temperature rise at an ambient temperature of 90°C

Epoxy-encapsulated for environmental protections and superior strength to withstand all types of reflow soldering
