SC Series: MIS Chip Capacitors
Features

Readily available from stock High reliability silicon oxide-nitride dielectric Low loss -- typically 0.04 dB in a 50 system Operation through 26 GHz Wide temperature operation
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% electrical test and visual inspection is always available if required.

Characteristic Operating temperature range (TOP) Storage temperature range (TSTG) Dielectric withstanding voltage Value -65 to +200 C -65 to +200 C 100 V
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 potentials 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.
