What are the key features of WFMA2010R0100FEA?

Ultra-low 0.01Ω resistance with 1% tolerance enables precise high-current sensing with minimal power loss in 2W power budget
Copper-manganese (CuMn) resistive element delivers near-zero temperature coefficient for stable current measurement across wide temperature ranges
Anti-sulfur construction prevents resistance drift from sulfur contamination in industrial or automotive environments with H2S exposure

What is WFMA2010R0100FEA used for?

The WFMA2010R0100FEA is ideal for current sensing in DC-DC converters, motor drive circuits, and battery management systems where accurate high-current measurement at low resistance values is required. Its 2W power rating and CuMn element make it suitable for automotive battery monitoring, industrial servo drives, and switched-mode power supplies handling currents up to 14A. The anti-sulfur coating extends reliability in industrial panel environments with chemical exposure risks.

Frequently Asked Questions

What resistance value and tolerance does the WFMA2010R0100FEA offer for precision current sensing circuits?

The WFMA2010R0100FEA has a resistance of 0.01Ω (10 milliohms) with 1% tolerance, enabling accurate current sensing with only 0.1V drop at 10A, minimizing measurement error and power dissipation in high-current paths up to the 2W rated power limit.

Why use a CuMn alloy element in the WFMA2010R0100FEA instead of standard nichrome for current sensing?

CuMn (copper-manganese) alloy has a very low temperature coefficient of resistance, typically below 50 ppm/°C, compared to 200-400 ppm/°C for nichrome, ensuring that the 0.01Ω sense resistance remains stable across -55°C to +155°C operating range and maintains accurate current measurement in automotive and industrial thermal environments.

How does the anti-sulfur feature of the WFMA2010R0100FEA extend service life in industrial installations?

Industrial environments can contain hydrogen sulfide (H2S) gas at concentrations above 10 ppb, which corrodes standard silver-containing terminations and causes open-circuit failures. The WFMA2010R0100FEA's anti-sulfur construction uses sulfur-resistant terminal materials that withstand H2S exposure per AEC-Q200 test conditions, maintaining stable 0.01Ω resistance over the component's service life in harsh factory or automotive under-hood settings.
