12 Amp Active EMI Filter for 48 V DC Bus

Description

Features

• >40 dB CM attenuation at 250 kHz

• >70 dB DM attenuation at 250 kHz

• 80 Vdc (max input)

The QPI-1 active EMI filter attenuates conducted

common-mode (CM) and differential-mode (DM) noise

over the CISPR22 frequency range of 150 kHz to 30

MHz. The product is designed for use on a 48 Vdc bus

(36-76 Vdc). The QPI-1’s 12 A rating supports multiple

DC-DC converter loads up to a PCB temperature of

60°C. At a 100°C PCB temperature the QPI-1 supports

10 A loads. Designed for the telecom and ITE bus range,

• 12 Amp rating

• 100 Vdc surge 100 ms

• 1,500 Vdc Hi-pot hold off to Shield Plane

• 1.0” x 1.0” x 0.2” SiP (System-in-Package)

• SMT Land Grid Array (LGA)

• -40° to +100°C PCB temperature (See Fig. 5)

• Active filtering reduces volume and height

• Efficiency 99% at full load

the QPI-1 supports the PICMG 3.0 specification for

filtering system boards to the EN55022 Class B limits.

In comparison to passive solutions, the use of active

filtering reduces the volume of the common-mode

choke, providing a low profile, surface mount device.

Smaller size saves valuable board real estate and the

reduced height enhances airflow in blade applications.

• Connect in series for higher attenuation

• TÜV Approved

The QPI-1 is available in a 1.0" x 1.0" x 0.2" SiP (System

in Package) with LGA mounting. QPI-1-EVAL1 kits are

available for testing the QPI-1. The evaluation board

has a mounted QPI-1 with screw terminals for quick

in-circuit testing.

Applications

• ATCA blades

• Telecom base stations

• IBA & distributed power
