SMT Power Inductors - LPT3305 Series
This product has been discontinued
as of September 1, 2000
Recommended alternative is LPO2506 series. Existing customers
will be supported. For more information, please contact Coilcraft.
These parts are designed for applications requiring low
profile parts – 1.8 mm high. The toroid construction
minimizes EMI while the ceramic cover provides the
best possible surface for pick and place handling.
Applications include notebook computers and PC cards
as well as wireless communication products.
