4900 SERIES
Dual Winding Surface Mount Inductors
FEATURES
■ 2.2µH to 880µH1 ■ Up to 9.5A IDC ■ Bobbin Format ■ Dual Winding ■ Surface Mounting ■ Integral EMI Shield ■ Compact Size ■ Tape and Reel Packaging ■ No Voltage Breakdown at 500VDC
DESCRIPTION
The 4900 series is a range of dual wind inductors offering flexible options. Windings have a 1:1 ratio and can be connected in series or parallel to create a wide range of inductance combinations. The secondary winding could be used as a feedback winding in switched mode power supplies.
1 When connecting windings in series, inductance
will be 4 times the nominal figure shown.
2 Specifications typical at TA=25°C
3 If current is flowing in both windings the maximum
DC current occurs when either the inductance falls to 75% of its nominal value or when its temperature rise reaches 40°C, whichever is sooner.
