Picor Introduces New EMI Filters Optimized for VI Chip Applications
PicorCorp., a subsidiary of Vicor Corp. (NASDAQ:VICR) introduced two new product additions to its QPI QuietPower® input filter product line: the QPI-12 VI Chip EMI filter and the QPI-10 VI Chip EMI filter with hot swap, for AdvancedTCA® applications.
The QPI-12 EMI filter is specifically designed to attenuate conducted common-mode and differential-mode noise, to comply with CISPR22 requirements. The filter is designed to operate from 10 Vdc to 76 Vdc and supports 7 A loads up to 80°C; it is parallelable for higher power and occupies only 0.5" square inch of board area.
The QPI-10 complies with AdvancedTCA PICMG3.0® requirements for hot insertion and board-level conducted noise limitations defined by EN 55022 class B. The EMI filter provides conducted common-mode and differential-mode noise attenuation from 150 kHz to 30 MHz. The QPI-10 is designed for use on a 48- or 60-volt DC bus (36-76 Vdc). The in-rush current limit and circuit breaker are designed to satisfy the 200 W per board PICMG3.0 limit up to 70°C PCB temperature around the QPI-10.
"Both of these devices are small, low-profile SiPs that reduce the total noise spectrum to well below the EN55022 Class B Quasi-peak detection limit," said Bob Lanoue, Picor Systems & Applications Manager. "The QPI-10, of course, also meets PICMG3.0 requirements for hot insertion." Both are optimized for use upstream of the VI Chip Factorized Power Architecture.
QPI-12 is packaged in a 12.4mm x 25mm x 4.5mm size LGA SiP; QPI-10 is a 25mm x 25mm x 4.5mm SiP. Both products are packaged in anti-static tubes. QPI-12 sells for $6.75 and QPI-10 sells for $12.10, in 1,000-piece quantity. Delivery is stocked to 6 weeks.
