Designed for replacing conventional array filters in medical implantable devices is the SYFER E03 (X2Y) range. Available in case sizes from 0805 to 2220 these are integrated passive devices featuring both common and differential mode capacitors in a single MLCC chip.

C0G and X7R dielectric versions are both available options.

Alternatively, the SYFER E01 and E07 ranges of feed through MLCC ‘C’ filters have extended working voltages from 25Vdc to 200Vdc, and in certain cases up to 500Vdc.

These surface mount EMI filter 3 terminal chip devices are designed to offer reduced inductance compared to conventional MLCC’s when used in signal line filtering.

The filtered signal passes through the chip’s internal electrodes with the ‘noise’ filtered to the grounded side contacts, resulting in reduced length noise transmission paths.

Available in C0G/NP0 & X7R dielectrics, in case sizes 0805 to 1812.  Current ratings are 300mA to 3A with voltage ratings of 25Vdc to 200Vdc (500Vdc in some case sizes).

The SBSP range of surface mount pi-filters have an operating temperature range of -55°C to 125°C making them suitable for mil/aerospace applications.

The use of X7R and C0G ceramic dielectrics sees capacitance values from 22pF to 150nF with a 1A current rating.  They have working voltages up to 100Vdc.
