Notes

*¹ Suffix “M” for 20% tolerance, Suffix “K” for 10% tolerance or Suffix “J” for 5% tolerance
Optional tolerances available; please contact factory
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

Incremental Current is the current which causes a 5% maximum change in inductance

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

Reflow Profiles

Please select the reflow soldering profile below that best suits your process. These reflow profiles represent typical industry standards. If you need additional assistance please contact Gowanda Electronics directly.

Reliability Data

Please note that reliability testing (HRIP Life Test) has been done for many, but not all, of Gowanda Electronics' products, in keeping with the needs of specific applications. Please use the information in this table as a guide; for additional assistance please contact Gowanda.
