## **DESCRIPTION** 

The 4900S series is a range of bobbin-wound, surface-mount inductors designed for use in switching power supply, and power line fi lter circuits. The parts are suitable for any application requiring a high saturation current in a low-profi le package. The devices have an integral ferrite shield to reduce EMI.

About Novapart

Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Request a quote →

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
