SC01500710 Description

Alpha’s MIS Chip Capacitors are available in a wide rangeof sizes and capacitance values. They are frequently usedin applications requiring DC blocking, and RF bypassing,or as a fixed capacitance tuning element in filters,oscillators, and matching networks. The devices have adielectric composed of thermally grown silicon dioxide overwhich a layer of silicon nitride is deposited. This dielectricpossesses a low temperature coefficient of capacitance,very high insulation resistance. The devices also exhibitexcellent long term stability making them suitable for highreliability applications. The capacitors have a highdielectric breakdown which permits the use of thindielectrics resulting in larger capacitance per unit area thanour previous catalog offerings. The temperature coefficientis 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 lowerinsertion loss of 0.04 dB, in a 50 Ω system. Insulationresistance is greater than 105M Ω. To accommodate highvolume automated assembly methods, wafers can besupplied on expanded film frame. To reduce cost, chipscan be supplied with only sample testing packaged in vials.Packaging in waffle packs with 100% electrical test andvisual inspection is always available if required.
