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:
Pcs./12” Reel maximum:
Pitch between parts:
Inside tape spacing:
Class:
that will reduce the initial inductance by 5%
temperature rise at an ambient temperature
of 90°C.
