7 A V·I Chip EMI Filter

Description

Features

• >40 dB CM attenuation at 1 MHz

The QPI-12 EMI filter is specifically designed to

attenuate conducted common-mode (CM) and

differential-mode (DM) noise of Vicor’s V•I Chip

products to comply with the CISPR22 standard

requirements for conducted noise measurements. The

filter is designed to operate up to 80 Vdc and supports

7 A loads up to 60°C without derating.

• >60 dB DM attenuation at 1 MHz

• 80 Vdc (max input)

• 100 Vdc surge 100 ms

• 1,500 Vdc hipot hold off to shield plane

• 7 A rating

Designed for the telecom bus range, the V•I Chip EMI

Filter supports the PICMG^®3.0 specification for

filtering system boards to the EN55022 Class B limits.

• 12.4 x 25 x 4.5 mm SiP (System-in-Package)

• Low profile LGA package

• -40° to +100°C PCB temperature (see Figure 6)

• Efficiency >99%

• TÜV Certified

Applications

• Telecom and ATCA boards

• V•I Chip input power filter
