QPI 5 V to 50 V 7 A V•I Chip Optimized Input EMI Filter Low profile LGA package
Product Branding Change for MQPI, QPI and QPO filters The purpose of this notice is to make you aware of a change in the way Vicor will brand MQPI, QPI and QPO Filters. Reason for the change: As part of a corporate business unit merge the Picor logo will be phased out and will be replaced with the Vicor logo. In addition, Vicor will convert from ink marking to a laser marking process on lidded units and update labels on open frame units (model numbers ending with a "-01") to mark the Vicor logo, model number, lot and date codes. This change will impact all Vicor MQPI, QPI and QPO filters.

Features and Applications
The QPI-11LZ is a part of QPI Family EMI filter. It is specifically designed to attenuate conducted common-mode (CM) and differential-mode (DM) noise of the Vicor V•I Chip products to comply with the CISPR22 standard requirements for conducted noise measurements.
The filter is designed to operate up to 36 Vdc and supports 7 A loads up to 60°C without derating. Designed for the military and industrial bus range, the V•I Chip EMI Filter supports the PICMG® 3.0 specification for filtering system boards to the EN55022 Class B limits. Two of these filters can be connected in parallel to double current capability up to 14 A with a minor effect on attenuation at 1 MHz.
