What are the key features of PTF5640K000BYEK?

Ultra-tight ±0.1% resistance tolerance on a 40 kΩ value ensures accurate voltage dividers and precision analog signal conditioning
Low ±10 ppm/°C temperature coefficient minimizes drift across the -55°C to +85°C operating range for stable reference networks
0.125 W through-hole axial metal film construction in the PTF56 form factor provides low noise and excellent long-term stability

What is PTF5640K000BYEK used for?

The PTF5640K000BYEK is designed for precision measurement instruments, calibration equipment, and high-accuracy analog front-end circuits where a 40 kΩ resistor with ±0.1% tolerance and ±10 ppm/°C drift is essential for maintaining signal accuracy over temperature. Its low noise metal film construction also makes it ideal for audio reference networks, medical diagnostic electronics, and laboratory bench instruments requiring stable, repeatable resistance values.

Frequently Asked Questions

What resistance value, tolerance, and temperature coefficient does PTF5640K000BYEK provide?

The PTF5640K000BYEK offers a 40 kΩ resistance with ±0.1% tolerance and a ±10 ppm/°C temperature coefficient. These specifications ensure that resistance drift across the full operating temperature range of -55°C to +85°C stays within tight bounds, suitable for precision analog designs.

How does the PTF5640K000BYEK compare to 1% tolerance resistors in precision voltage-divider applications?

A ±0.1% tolerance PTF5640K000BYEK delivers ten times better initial accuracy than a standard ±1% resistor at the same 40 kΩ value. Combined with the ±10 ppm/°C temperature coefficient, it maintains a voltage-divider ratio within ±0.15% from 0°C to 85°C, compared to ±2% or worse for standard parts.

What power rating and mounting style does the PTF5640K000BYEK use?

It is rated at 0.125 W (125 mW) continuous dissipation in a through-hole axial tubular package using horizontal mounting. This classic axial form factor is compatible with standard PCB drill patterns and wave-soldering processes used in precision instrument and industrial control board assemblies.

In which precision measurement or calibration scenarios is PTF5640K000BYEK a preferred choice?

The PTF5640K000BYEK is preferred in calibration reference bridges, ADC input attenuators, and precision op-amp feedback networks where the 40 kΩ, ±0.1% value must remain stable across a -55°C to +85°C environment. Its ±10 ppm/°C drift limits gain error to under 1 mV per 100°C in a typical instrumentation amplifier stage.
