| High Light | 330 shielded power inductor ，33uH shielded power inductor ，High Current shielded inductor | ||
The SMD 330 power inductor is a magnetically shielded, surface-mount (SMT) power choke marked "330", which stands for a nominal inductance of 33µH. It uses a ferrite drum core wrapped in a moulded magnetic resin body, giving low EMI radiation, low DCR and a flat square top surface that is ideal for automatic pick-and-place and vacuum-nozzle handling.
Typical use is the energy-storage inductor in DC-DC buck/boost converters, switching power supplies (SMPS), LED drivers and on-board power modules. Custom inductance (1µH–1000µH), size, current rating and packaging are available from our own winding and moulding lines.
