7A Active EMI Filter SiP for 24V_DCBus

Product Description

Features & Beneﬁts

• 65dB CM attenuation at 250kHz (50Ω)

• 80dB DM attenuation at 250kHz (50Ω)

• 40V_DC(max input)

The QPI-3 active EMI ﬁlter attenuates conducted common-mode

(CM) and differential-mode (DM) noise over the CISPR22 frequency

range of 150kHz to 30MHz. The product is designed for use on

24V_DCbus (10 – 40V_DC) systems, with 100V_DCsurge capability. The

QPI-3’s 7A rating supports multiple DC-DC converter loads up to

an ambient temperature of 110°C without de-rating. Designed for

the telecom and ITE bus range, the QPI-3 supports the PICMG^®

3.0 speciﬁcation for ﬁltering system boards to the EN55022

Class B limits.

• 100V_DCsurge 100ms

• 707V_DChipot hold off to shield plane

• 7A rating

• Low-proﬁle LGA package

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.

•

~1in²area

• –40 to +125°C ambient temperature (see Figure 9)

• Efﬁciency >99%

The QPI-3 is available as a lidded or an open-frame SiP

(System-in-Package) with LGA mounting. Evaluation boards are

available to allow for quick in-circuit testing of the QPI-3LZ within

an existing system design.

• Connect in series for higher attenuation

• TÜV certiﬁed
