Tiny Thin-Film Resistor Chips Suit Microwave Applications

June 23, 2003

The Electro-Films series MIB, MIC, MID, and MIF resistor chips measure just 0.010 by 0.020 in., making possible low-shunt capacitance and strip-line resistor design optimized for microwave-circuit functions. These Vishay Intertechnology devices 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 a TCR range of ±25 ppm/°C to ±200 ppm/°C.

The chips have a stray capacitance of 0.2 pF, maximum operating voltage of 100 V, dielectric breakdown of 400 V, and 25- to 200-mW maximum dc power ratings at 70°C. They operate from −55°C to 125°C. Samples are available now with lead times of six weeks for production quantities. Pricing for 1% parts in 1k-piece lots ranges from $0.50 to $1.00, depending on style.
