Description

General part information

33 Series

The 3300 series vertical-mount through-hole Power Inductor with toroidal construction and tin pin finish. Due to the toroidal construction, they exhibit a very low EMI as stray flux is kept to a minimum. Typical applications include switching regulators and power line filtering.
