Malvern, Pa. Vishay Intertechnology, Inc. has launched an improved Z201 ultra-high-precision Z-Foil resistor, which the company says is the industry's first device to provide a very low temperature coefficient of resistance (TCR) of ±0.05 ppm/°C from 0°C to 60°C and ±0.2 ppm/°C from -55°C to 125°C, a low power coefficient of resistance (PCR) of ±5 ppm at rated power, tight tolerances of ±0.005%, and a load life stability of ±0.005%.
The Z201 device has a load-life stability of ±0.005% for 2,000 hours at 70°C, a resistance range of 10 ohms (Ω) to 100 kΩ, a power rating of 0.3 W at 125°C, current noise of less than -40 dB, and a thermal EMF of 0.1 microvolt °C maximum (0.05 typical). It offers high-frequency operation with a rise time of 1.0 ns without ringing, and features a non-inductive, non-capacitive design. The device offers a small package size, and functions as a drop-in replacement for the previous generation S102C/K series of resistors. Click the link for the Z201 datasheet.
In addition, the Z201 resistor has an electrostatic discharge (ESD) above 25,000 V, putting it well over the top requirements of all three of the highest ESD standard classifications, making it exceptionally insensitive to ESD, said the company.
Vishay said this breakthrough level of stability, more than an order of magnitude better than any other resistor technology, allows designers to guarantee a high degree of accuracy in fixed-resistor applications. Applications include precision amplifiers, high-precision instrumentation, medical and automatic test equipment, high-end stereo equipment, electron beam scanning and recording equipment, as well as military, aerospace, and down-hole equipment and instrumentation.
Samples and production quantities of the Z201 Z-Foil resistor are available now, with lead times of four to six weeks for larger orders. Pricing for U.S. delivery varies with value, tolerance, and quantity.
