The component utilizes an iron core and is constructed as an unshielded, nonstandard leaded device. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• Utilizes an iron core for magnetic flux conduction
• Provides high precision with ±1% inductance tolerance
• Features an unshielded design suitable for specific layout requirements

Applications

• RF circuit filtering
• General purpose inductive applications
• Signal processing circuits

Procurement Notes

Verify the exact physical dimensions and lead configuration against the official datasheet, as the package is classified as nonstandard. Confirm that the 17 Ohm DC resistance aligns with your circuit's power loss constraints. Ensure the 38 mA current rating meets the operational requirements without saturation issues.

Selection Notes

Select this component when precise inductance values are critical due to its tight ±1% tolerance. The unshielded construction requires careful PCB layout to minimize electromagnetic interference coupling with adjacent traces. Verify compatibility with the target operating temperature range of -55°C to 125°C.
