No. Smithfield, R.I. Picor, a subsidiary of Vicor Corporation, has expanded its QPI QuietPower input filter product line with two product additions that are optimized for use with Vicor's V-I Chip devices. The QPI-12 V-I Chip EMI filter and the QPI-10 V-I Chip EMI filter with hot swap are suitable for AdvancedTCA applications.
The QPI-12 EMI filter attenuates conducted common-mode and differential-mode noise in compliance with CISPR22 requirements. The filter operates from 10 Vdc to 76 Vdc and supports 7 A loads up to 80°C. Two filters can be connected in parallel for higher power. The QPI-12 is packaged in a 12.4 x 25 x 4.5-mm size LGA SiP, and occupies 0.5 square-inch of board area. Click the link for the QPI-12 datasheet.
The QPI-10 complies with AdvancedTCA PICMG 3.0 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 to 76 Vdc). The in-rush current limit and circuit breaker are designed to satisfy the 200 W per board PICMG 3.0 limit up to 70°C PC-board temperature around the QPI-10. The QPI-10 is housed in a 25 x 25mm x 4.5mm SiP. Click the link for the QPI-10 datasheet.
Packaged in anti-static tubes, the QPI-12 EMI filter is priced at $6.75 and the QPI-10 sells for $12.10, in quantities of 1,000. Delivery is from stock to six weeks.
