Vishay : Miniature Z-foil resistors offer ultra-high-precision



Vishay Intertechnology, Inc. announces the Z202 series of miniature ultra-high-precision Z-Foil resistors, which provide a typical TCR of ±0.05ppm/°C from 0°C to +60°C, PCR (DR due to self heating) of ±5ppm at rated power, tolerances to ±0.01%, load life stability of ±0.01%, and can be trimmed to any specific value at any tolerance within the standard resistance range of 5Ω to 30kΩ.

The Z202 is a miniaturized version of Vishay’s Z201. Constructed with a Bulk Metal® Z-Foil element, it provides all of the inherent performance benefits of Z-Foil resistors. Vishay’s revolutionary Z-Foil technology significantly reduces the resistive component’s sensitivity to ambient temperature variations and applied power changes. This breakthrough level of stability, more than an order of magnitude better than that offered by other resistor technologies such as thin film, wirewound, and thick film, allows designers to guarantee a high degree of accuracy in fixed-resistor applications.

Applications for the new Z202 series include precision amplifiers, high-precision instrumentation, medical and automatic test equipment, high-end stereo equipment, electron beam scanning and recording equipment, and military, aerospace, and down-hole equipment and instrumentation.

The Z202 devices have a load-life stability of ±0.01% for 2000 hours at 70°C; a power rating of 0.125W at +125°C (0.25W at +70°C); current noise of < -40dB; and thermal EMF of 0.1mV/°C.

Because of its specifications, the new Z202 resistor will reduce solution costs, allowing designers to rely on consistent resistor performance to overcome the limitations of other components, lowering the total error budget.

Turnaround time for prototype samples is from 72 hours through our Prototype Fastlane Service (PFS). Production quantities are available now, with lead times of four to six weeks.
