WFC Series Metal Foil Current Sense Resistors

Vishay’s metal foil current sense resistors offer ultra-low sensing resistance in small packages

Image of Vishay's WFC Series Metal Foil Current Sense ResistorVishay’s WFC series of current sense resistors offer low resistance values in the smallest footprint in their current sense portfolio. The foil on ceramic construction of the WFC series enables high power capability, lower TCR, and reaches lower resistance values than is available with comparable SMD thick-film current sense resistor technology. The high power density and lower resistance values allow for reduced board space and better measurement accuracy and efficiency. These features make it an ideal choice for designers that require reduced power dissipation and improve temperature stability. For the best performance in the smallest package size in Vishay’s SMD current sense portfolio, the WFC series is the solution.

Features
  • Resistance range: 1 mΩ to 180 mΩ
  • Vishay's smallest current sense package size, 0402
  • High power density
  • TCR down to ±50 ppm/°C
  • Side termination with the 0508 and 0612
  • Power rating: up to 2 W
  • More accurate current measurements
Applications
  • Telecommunications: power management in cell phones and DC/DC converters
  • Computers: power management, safety, DC/DC converters, and VRMs
  • Consumer: air-conditioning, heat-pumps (inverter controls), and white-goods (inverter controls)
  • Industrial: air-conditioning, refrigeration (inverter controls), motor control, and power factor correction
