DESCRIPTION

The P7600 family comprises high-energy-density
surface mount inductors.  The family employs
helical windings of rectangular wire, giving
excellent DC resistance, thermal efficiency and
high frequency performance. A distributed gap
powder core is used, yielding stable inductances at
very high currents with a closed magnetic current.

Components are supplied with Pb-free
terminations in tape and reel packaging, and are
suitable for Pb-free and conventional placement
and reflow.

Notes

1.  Inductance measured at 100kHz, 100mV.
2.  Rated current is the current at which the temperature rise is 45ºC.
3.  Saturation current, I

sat

, is the DC current at which the zero-current inductance falls by 10%.

For this family, inductance falls by around 25% for a current of 2x I

sat.

4.  Operating temperature -25ºC to +105ºC.
5.  For non-standard inductance values, please contact Profec.
