DESCRIPTION

The P7608 family comprises high-energy-density
surface mount inductors.  The family employs
copper foil windings, giving excellent DC
resistance, thermal efficiency and high frequency
performance. The core is a closed magnetic circuit
to afford magnetic shielding.

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, 1V.
2.  Rated current, I

DC,

 is the current at which the temperature rise is 40ºC (max) or the DC current at which

the zero-current inductance drops by 25% (max) whichever is less.

3.  Operating temperature -25ºC to +85ºC.
4.  For non-standard inductance values, please contact Profec.
