NOTES:

• Operating temperature -55°C to +125°C

• Parts are printed

*Saturation current is the approximate value

**Rated current is based on a 35°C

In order to obtain the highest possible satura-

tion (incremental) current, a low resistivity fer-

rite core is used for this series. The core will

appear as a resistor of about 1,000 OHMS in

parallel with the winding and should be taken

into consideration in circuits with a high AC

voltage (Ripple).

TAPE AND REEL SPECS:

Class:

that will reduce the initial inductance by 5%

temperature rise at an ambient temperature

of 90°C.
