MQ Series – Medical Grade MLCC
General Specifications
GENERAL DESCRIPTION
AVX offers a wide variety of medically qualified passive components.
Medical devices require the utmost reliability with respect to the
components incorporated into the designs. Advanced design
qualification requirements, in-process controls and requirements and
lot acceptance testing are implemented to ensure these components
will meet the superior reliability levels of a life supporting application.
AVX medical MLCC reliability documents provide an advanced level
of designing, manufacturing, testing and qualification that places AVX
as the top supplier and industry leader of medically qualified MLCCs.
AVX MQ series of medically qualified ceramic capacitors are available
in EIA case sizes ranging from 0402 to 2225, at typical voltage
ratings between 4 – 200 Vdc with various termination options
including Sn, SnPb solder, and Au.
