QPI-21

NRTL US

Active EMI Input Module for 48 Vdc Bus

Product Description

Features

• 45 dB CM attenuation at 250 KHz (50 Ω)

• 80 dB DM attenuation at 250 KHz (50 Ω)

• 80 Vdc (max input)

The QPI-21 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 in 48 Vdc bus (36 – 76 Vdc) systems, with

100 Vdc surge capability. The QPI-21’s 14 A rating supports

multiple DC-DC converter loads up to an ambient

temperature of 65°C without de-rating. Designed for the

telecom and ITE bus range, the QPI-21 supports the PICMG®

3.0 speciﬁcation for ﬁltering system boards to the EN55022

Class B limits.

• 100 Vdc surge 100 ms

• 1,500 Vdc hipot hold off to shield plane

• 14 A rating

• 25.3 x 25.3 x 5.0 mm Lidded SiP (System-in-Package)

• 24.9 x 24.9 x 4.4 mm Open-frame SiP

• Low profile LGA package

In comparison to passive solutions, the use of active ﬁltering

reduces component size and therefore reduces the overall

package size. The Picor QPI-21 smaller size saves valuable

board real estate and the reduced height enhances airﬂow.

• -40° to +125°C Ambient temperature (see Figure 14)

• Efficiency >99%

• Connect in series for higher attenuation

• Pads for additional X filtering capacitance

• cTÜVus approved to UL/CSA 60950-1 and EN 60950-1

The QPI-21 is available as a lidded or an open-frame SiP

(System-in-Package) module with LGA mounting. Evaluation

boards are available to allow for quick in-circuit testing of the

QPI-21LZ within an existing system design.

• CE marked to the LVD and RoHS Recast Directive

as applicable
