Applications
The Vishay Y16245K00000T9R is used in precision analog circuits requiring decade-stable reference networks, such as precision voltage dividers, Wheatstone bridges, and calibration standards in test and measurement instruments. Its ±0.2ppm/°C TCR ensures the 5kΩ resistance shifts by less than 1mΩ per degree Celsius, critical for high-resolution ADC input networks, precision current-sense dividers, and medical instrumentation where drift over temperature corrupts measurement accuracy. It is also specified in aerospace and defense electronics where MIL-grade stability and traceability to NIST standards are required.

Frequently Asked Questions
How stable is the Y16245K00000T9R resistance over temperature, and what does ±0.2ppm/°C mean in practice?
The Y16245K00000T9R has a temperature coefficient of ±0.2ppm/°C, meaning the 5kΩ resistance changes by only 0.001Ω per degree Celsius. Over a 100°C temperature range, total drift is just 0.1Ω — less than 0.002% change — making this resistor suitable for precision voltage references, ratio-metric bridges, and high-resolution ADC input networks where even 0.1% drift would corrupt measurement accuracy.
What tolerance does the Y16245K00000T9R carry, and for which precision measurement circuits is it a fit?
At ±0.01% tolerance, the Y16245K00000T9R guarantees the 5kΩ value is within ±0.5Ω of nominal at time of purchase. This precision is required in Wheatstone bridge sensor networks, precision current-shunt dividers, and 16-bit to 24-bit ADC input attenuators where resistor mismatch introduces gain error that standard ±1% resistors cannot control, even after factory calibration.
How does metal foil technology in the Y16245K00000T9R compare to thin-film resistors for low-noise applications?
Metal foil resistors exhibit current noise below 0.01µVrms/V, significantly lower than the 0.1µVrms/V to 1µVrms/V typical of thin-film types, because the bulk foil has no granular boundaries that generate 1/f flicker noise. For the Y16245K00000T9R at 5kΩ, this means the noise contribution in precision instrumentation amplifier gain-setting networks and hydrophone preamplifiers is negligible compared to the Johnson-Nyquist thermal noise floor, preserving system dynamic range.
