Andover, Mass. - Picor is billing its QPI-1 as the industry's first active electromagnetic interference (EMI) filter for 48-volt dc/dc telecom applications. The unit delivers 40 dB of common-mode attenuation and more than 80 dB of differential-mode attenuation at 500 kHz. As an active filter, it's designed to attenuate noise over the entire frequency range (no resonant elements) and will eliminate ringing on the input of the converter if there are line and load transients, the company said.
Measuring 1 x 1 x 0.2 inch, the QPI-1 is about half the size of the smallest passive filter providing competing performance, said Picor. The part can also be mounted vertically, saving as much as 80 percent in board space. It's designed to support all dc/dc converters for IT and telecom applications.
Available in an LGA or BGA package, the QPI-1 is priced at $19.50 each in lots of 1,000, shipped in antistatic tubes. Delivery is stock to six weeks.
