SC Series: MIS Chip Capacitors
DATA SHEET
Description
Skyworks MIS Chip Capacitors are available in a wide range of
sizes and capacitance values. They are frequently used in
applications requiring DC blocking, 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 and 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
large capacitance per unit area. 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
accommodate high volume automated assembly
methods, wafers can be supplied on expanded film frame. To
reduce cost, chips can be supplied with only sample testing
packaged in vials. Packaging in waffle packs with 100% elec-
trical test and visual inspection is always available if required.

Absolute Maximum Ratings
Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION: Although this device is designed to be as robust as
possible, Electrostatic Discharge (ESD) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.

Performance Data
Tests on typical MIS capacitors at L and S band show insertion
loss to be 1/2 to 1/3 that of equivalent ceramic type capacitors,
without any of the associated resonance problems. Power tests
indicate that the only limitation is the actual breakdown voltage
of the device (see data section). A typical insertion loss versus
frequency graph is shown in Figure 1. This data is taken from an
actual tests circuit with series mounted beam-lead or chip
capacitors on a 50
microstrip transmission line. The apparent
higher loss at lower frequencies on the lower capacitance units is
strictly due to the capacitive reactance of the capacitor.
