MIS Chip Capacitors

DESCRIPTION
Transcom's MIS Chip Capacitors are available in a wide range of sizes and capacitance values. They are designed to be use as DC blocks coupling filter elements, RF bypass, microwave circuit resonant elements and a fixed capacitance tuning elements in filters, oscillators, and matching networks.
The devices have long-term stability making them suitable for high reliability application. The temperature coefficient is less than 200 ppm/°C, and operation is suitable from –65 °C to 200 °C. Differing from ceramic capacitors,Transcom's MIS Chip Capacitors have high Q and lower insertion loss of 0.1 dB in a 50W system. Insulation resistance is greater than 106 MW.
The wafers are supplied on expanded 6" hoop for high volume automated assembly methods and 100% DC tested to assure consistent quality. Capacitors are packaged in gel packs and 100% visual inspection is always available if required.


DIE ATTACH AND WIRE BONDING
Transcom's MIS chip capacitors are processed with a high quality gold metallization for thermo-compression, thermo-sonic or ultrasonic wire bonding. The top plate of the capacitors is 99.99% sputtered gold with a TiW barrier and typical 3 mm of Au which is suitable for Gold-tin or gold germanium eutectic solders.Epoxy die attach is also acceptable.
