Compared to Conventional Passive Filter Designs,
Picor's Advanced Active Filtering Reduces PCB Area,
Increases Attenuation Density, Reduces Susceptibility, and
Reduces Power Dissipation
ORLANDO, FL, Feb 06, 2012 (MARKETWIRE via COMTEX) --APEC 2012
-- Vicor Corporation (NASDAQ: VICR), today announced the
introduction of the Picor QuietPower(R) QPI-21 High Density
Active EMI Filter for DC-DC converters. Supporting 48V DC-DC
converter designs up to 14A for data communications and
telecommunication applications, the QuietPower QPI-21
provides > 99.5% efficiency while achieving a new level of
filtering performance.
The QuietPower QPI-21 is packaged in a high density,
one-square-inch Land Grid Array (LGA) surface mount package
that reduces PCB board area consumed by EMI filtering,
ensuring ultra efficient board utilization. The filter's
0.2" height maximizes airflow for space constrained
designs, making it an ideal fit for advanced
blade-architecture applications. These density advantages are
complemented by new performance enhancements enabling higher
frequency attenuation across various system configurations
than earlier-generation QuietPower QPI-series filters.
The QuietPower QPI-21 attenuates conducted common mode (CM)
and differential mode (DM) noise over the CISPR22 frequency
range of 150 kHz to 30 MHz (45dB for CM and 80dB for DM
attenuation at 250 KHz). The filter is designed for use in
48V bus (36 - 76V) systems, with 100VDC/100ms surge
capability, and operates over a wide temperature range of -40
degreesC to +125 degreesC and up to an ambient temperature of
65 degreesC without de-rating. The QPI-21 supports the
PICMG(R) 3.0 specification for filtering system boards to the
EN55022 Class B limits and is also tolerant to all DC-DC
converter grounding schemes.
The QuietPower QPI-21 is the newest addition to the Picor
QuietPower portfolio of high density EMI input and output
filters, addressing multiple voltage rail/bus needs for
applications in aerospace and industrial, in addition to
datacom and telecom. The QuietPower QPI-21, like all
QuietPower filters, is a universal filter for use with DC-DC
converters from any manufacturer.
"The combination of form factor, attenuation
performance, and efficiency within the QuietPower QPI-21
exceeds the capabilities of conventional passive
filters," said Chester Firek, Senior Product Marketing
Manager, Picor. "These advantages distinguish the
QuietPower QPI-21 as the ideal EMI filter for demanding, high
density datacom and telecomm systems with board space and/or
airflow constraints."
Pricing and Availability The QuietPower QPI-21 is available
in two package types: the QPI-21LZ (lidded LGA package) and
the QPI-21LZ-01 (open frame LGA package). Both QPI-21 package
types are available at $17.04 for OEM quantities. For a
