DATA SHEET SC Series: MIS Chip Capacitors Applications Systems requiring DC blocking or RF bypassing Fixed capacitance tuning element in filters, oscillators, and matching networks Features Readily available from stock High reliability silicon oxide-nitride dielectric Description Low loss: typically 0.04 dB in a 50 system Skyworks Metal Insulator Silicon (MIS) chip capacitors are Operation through 26 GHz available in a wide range of sizes and capacitance values. The Wide temperature operation devices have a dielectric composed of thermally grown silicon dioxide over which a layer of silicon nitride is deposited. This dielectric has a low temperature coefficient of capacitance and very high insulation resistance. The MIS chip capacitors also exhibit excellent long-term stability, which makes 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 than 50 ppm/C, allowing the capacitors to operate from 65 C up to 200 C. Compared to ceramic capacitors, Skyworks MIS chip capacitors offer higher Q and an insertion loss of 0.04 dB in a 50 system. Insulation 5 resistance is greater than 10 M. To accommodate high volume, automated assembly methods, wafers can be supplied on expanded film frames. To reduce cost, chips can be supplied packaged in vials with sample testing only. Packaging in waffle packs with 100 percent electrical testing and visual inspection is also available. Skyworks Solutions, Inc.

MIS Capacitors Absolute Maximum Ratings Parameter Symbol Minimum Typical Maximum Units Dielectric withstand voltage 100 V Operating temperature TOP 65 +200 C Storage temperature TSTG 65 +200 C Note: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. 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 should be used at all times.

Power tests indicate that the only limitation is the actual A graph of typical insertion loss versus frequency is shown in breakdown voltage of the device. Figure 1. This data is taken from an actual test circuit with series mounted beam-lead or chip capacitors on a 50 microstrip Figure 2 illustrates the use of MIS capacitors in a typical Single- transmission line. The apparent higher loss at lower frequencies Pole, Double-Throw (SPDT) circuit. on the lower capacitance units is strictly due to the capacitive reactance of the capacitor.
