Description
Dielectric Withstanding Voltage
Alpha’s MIS Chip Capacitors are available in a wide range
of sizes and capacitance values.They are frequently used
in applications requiring DC blocking, and RF bypassing,
or as a fixed capacitance tuning element in filters,
oscillators, and matching networks. The devices have a
dielectric composed of thermally grown silicon dioxide over
which a layer of silicon nitride is deposited.This dielectric
possesses a low temperature coefficient of capacitance,
very high insulation resistance. The devices also exhibit
excellent long term stability making them suitable for high
reliability applications. The capacitors have a high
dielectric breakdown which permits the use of thin
dielectrics resulting in larger capacitance per unit area than
our previous catalog offerings.The temperature coefficient
is less that 50 ppm/°C, and operation is suitable from
-65°C to 200°C. Compared to ceramic capacitors,
Skyworks’MIS chip capacitors offer higher Q, and a lower
insertion loss of 0.04 dB, in a 50 Ω system. Insulation
