Description

M/A-COM’s MA4M series of MNS (metal-nitride-silicon) sili­con chip capacitors is designed specifically for high reliability and
repeatable performance in microwave circuit ap plications . These
capacitors are made using a low press ure chemical vapor depos i­tion (LPCVD) that results in dense, uniform nitride layers. These
capacitors exhibit higher capacitance per unit area (resulting in
smaller chip size) than similar MOS, MIS and ceramic capacitors.
Evaporated gold contacts are used t o provide an easily bondable
metal pad on the capacitor chip. M/A-COM MNS capacitors have
shown no measurable capacitance change when subjected to the
rated standoff voltage of 150ºC.

The MA4M series of chip capacitors is an excellent choice for use
in hybrid microwave circuits up through Ku-band, where low
loss, high reliability, small size and temperature stability are
prime concerns.

These chip capacitors are suited for applications requiring DC
blocks, coupling capacitors, bypass capacitors, capacitive loads
and tuning elements in oscillators, multipliers and filters.
