Thin-Film Chip Resistors measure 0.010 by 0.020 in.
Press Release Summary:
Electro-Films Microwave Resistors employ low shunt capacitance and strip-line resistor design optimized for microwave and RF circuits. With -55 to +125°C operating temperature range, products offer tolerance values down to ±1.0% and TCR values from ±25 to ±200 ppm/°C. With stray capacitance of less than 0.2 pF, MIB, MIC, MID, and MIF microwave resistor chips have 100 V max operating voltage, 400 V dielectric breakdown voltage, and 25-200 mW max DC power ratings.

Industry's Smallest Thin-Film Resistors for Microwave Applications Offer High Performance in Chip as Small as 0.010" by 0.020"
Low Shunt Capacitance and Strip-Line Resistor Design Optimized for Microwave Circuits
MALVERN, PENNSYLVANIA - May 13, 2003 - A series of thin-film single-value chip resistors, featuring excellent high-frequency response and low shunt capacitance for exceptional performance in hybrid assemblies and microwave and RF circuits, was announced today by Vishay Intertechnology, Inc. (NYSE: VSH).
In addition to dimensions as small as 0.010" (0.25 mm) by 0.020" (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 Ù to 1 kÙ and an overall resistance range to 20 kÙ. 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 100 V, a dielectric breakdown voltage of 400 V, 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.
Samples of the MIB, MIC, MID, and MIF chips are available now, with lead times of six weeks for production quantities. Pricing for U.S. delivery for 1% tolerance parts in 1,000-piece quantities ranges from $0.50 to $1.00 depending on the style.
Vishay, a Fortune 1,000 Company listed on the NYSE, is one of the world's largest manufacturers of discrete semiconductors (diodes, rectifiers, transistors, optoelectronics, and selected ICs) and passive electronic components (resistors, capacitors, inductors, and transducers). The Company's components can be found in products manufactured in a very broad range of industries worldwide. Vishay is headquartered in Malvern, Pennsylvania, and has plants in sixteen countries employing over 25,000 people. Vishay can be found on the Internet at www.vishay.com.
