QPI-12-CB1 carrier board featuring
the QPI-12LZ EMI filter
Introduction
The QPI-12-CB1 carrier board is an evaluation
board platform designed to demonstrate the EMI
capabilities of a QPI-12LZ filter, with any combination
of 48 V input PRM / VTM or BCM evaluation boards.
The QPI-12-CB1 board includes a pre-mounted filter
along with some additional components necessary to
demonstrate the full functionality of the filter, along
with mounting areas for V•I Chip evaluation boards.
This User’s Guide provides basic instructions for
assembly and use of the board. Further information on
the functionality of the V•I Chip boards, as well as the
QPI-12LZ can be found in the V•I Chip Evaluation Board
User’s Guide as well as the V•I Chip and QPI-12LZ
data sheets.
QPI-12LZ Product Description
The QPI-12LZ 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 continuous, with a 100 Vdc surge for 100 ms, and
supports 7 A loads up to 60°C without derating.
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.
