UNSHIELDED DRUM CORE (UP2.8B) UNI-PAC™ 2.8B

UNI-PAC™ 2.8

Low Cost, Low Profile 2.8mm

Power Inductors (Surface Mount)

Description

RoHS

2002/95/EC

• Miniature size and rugged construction

• Low DCR and high efficiency

• Suited for IR and vapor reflow solder

• Designed for high shock environments

• Frequency range 1kHz to 2MHz

• Ferrite core material

Applications

• DC-DC converters

• Filter inductors

• Signal conditioning

• Energy storage applications

• Computer, pager and battery powered equipment

Environmental Data

• Storage temperature range: -40°C to +125°C

• Operating ambient temperature range: -40°C to +85°C

range is application specific. Temperature rise is

approximately 40°C at rated RMS current. Maximum

operating temperature is 125°C including ambient.

• Solder reflow temperature: +260°C max. for 10 seconds

max.
