Characteristic Operating Temp Range (TOP) Value 100 V
Description

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, 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 to 200°C. Compared to ceramic capacitors, Skyworks' MIS chip capacitors offer higher Q, and a lower insertion loss of 0.04 dB, a 50 system. Insulation resistance is greater than 105M. To 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.

Part Number Structure SCXXXXYYZZ where: SC = Silicon Capacitor XXXX = Capacitance (pF) YY = Square Contact Size (mils) ZZ = Square Chip Size (mils)

Tests on typical MIS capacitors at L and S band show insertion loss 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 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.
