TCS8536 Series Current Sensing Resistors
The TCS8536 is a four-terminal, bus-bar, metal strip current shunt assembled using electron beam welding, rated at up to 36W and capable of carrying 1200A continuous current (at 0.025mΩ, terminal temperature not exceeding 140°C). Available resistance values are 0.025mΩ, 0.05mΩ, and 0.1mΩ with a tolerance of ±5%.
The series achieves a temperature coefficient of resistance (TCR) of less than ±100ppm/°C and an operating temperature range of −40°C to +170°C. Long-term stability is excellent, with resistance drift of no more than ±1.0% after 1000 hours at +125°C. Vibration resistance is rated to ±0.5% across a 10–2000Hz sweep at 5g. The design delivers very low inductance and outstanding frequency characteristics, making it suited to precision measurement and high-current power circuits.
Five voltage-sensing terminal configurations are offered: non-type (standard solder pads), hole type, tap type, pin type, and press-fit type, allowing the same resistive element to be specified across a wide variety of assembly and PCB integration requirements.
What are the TCS8536 Series Current Sensing Resistors?
The TCS8536 is a high-current, low-resistance shunt resistor designed for accurate current measurement in demanding power electronics applications. Its four-terminal (Kelvin) construction separates the current-carrying terminals from the voltage-sensing terminals, eliminating the effect of contact and lead resistance from the measurement and enabling accurate readings even at the milliohm resistance values characteristic of this series.
Fabrication by electron beam welding ensures a metallurgically sound, low-impedance joint between the copper bus-bar current terminals and the resistive alloy element. This construction method provides the mechanical robustness and thermal stability required for high-cycle, high-current environments. The flat bus-bar profile presents a low-inductance current path, preserving measurement accuracy at switching frequencies and during fast transients where inductance would otherwise introduce phase error or ringing.
The TCR of less than ±100ppm/°C means resistance variation with temperature is tightly bounded, maintaining measurement accuracy across the full operating range without requiring elaborate thermal compensation. The resistance-to-solvent rating and the 1000-cycle temperature shock qualification confirm suitability for industrial assembly processes and field environments with wide thermal excursions.
With resistance values extending down to 0.025mΩ, the TCS8536 targets applications where a large current must be measured with minimum insertion loss. At this resistance value, a 1200A current produces only 30mV across the shunt, keeping power dissipation low while providing a signal level sufficient for standard instrumentation amplifiers. The choice of five voltage-sensing configurations — non-type, hole, tap, pin, and press-fit — accommodates direct PCB mounting, panel wiring, and busbar integration without requiring changes to the resistive element itself.
