In addition to dimensions as small as 0.010 in. (0.25 mm) by 0.020 in. (0.5 mm), the Vishay Electro-Films Microwave Resistor series (MIB, MIC, MID, MIF) features a strip-line design that enables the design of higher-performance end products by providing a solution specifically optimized for microwave and RF requirements. Typical applications for new devices include amplifiers, oscillators, attenuators, couplers, and filters.
Devices in the Microwave Resistor series feature a microwave resistance range of 20 Ω to 1 kΩ and an overall resistance range to 20 kΩ. Tight tolerance values down to ±1.0% are available, with TCR values from ±25 ppm/°C to ±200 ppm/°C. These compact resistor chips provide a stray capacitance of less than 0.2 pF.
Vishay Electro-Films Microwave Resistor series devices feature a maximum operating voltage of 100V, a dielectric breakdown voltage of 400V, and 25 mW to 200 mW maximum dc power ratings at 70°C. The high-stability thin-film resistor element is tantalum nitride, which is self-passivating and moisture resistant. These resistors have an operating temperature range of -55°C to 125°C.
The MIB, MIC, MID, and MIF microwave resistor chips are built with an alumina substrate and gold terminations. They can be attached with conductive epoxy, ribbon-bonded, or wire-bonded. Other Vishay devices that are suitable for use with the Microwave Resistor series include wire-bondable capacitor chips, inductor chips, user-trim resistor chips, and TMR multi-value microwave products.
