Notes

Suffix "K" for 10% 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

Saturation current is the approximate value that will reduce the initial inductance by 5%

Parts are printed

In order to obtain the hightest possible saturation (incremental) current, a low resistivity ferrite core is used for this series; the core will appear as a resistor of about 1000 Ohms in parallel with the winding and should be taken into consideration in circuits with a high AC voltage (Ripple)
