Uni-Pac™ 2.8B SMT Power Inductors

Low-Profile / 2.8mm

Description

Uni-Pac™ surface mount inductors can be used in DC/DC

converters and as signal conditioning or filter inductors.

Because of their miniature size and rugged construction,

Uni-Pacs are ideally suited for products requiring higher

power per millimeter of PCB space. Such applications

include notebook computers, pagers and a variety of battery

powered equipment.

Features

•

Low DCR / High Efficiency

Suited for IR and Vapor Reflow Solder

Frequency Range 1kHz to 2MHz

Designed for High Shock Environments

Ideal for Energy Storage Applications
