Power Metal Strip

Power Metal Strip is a technology invented by Dr. Felix Zandman, founder of Vishay Intertechnology, Inc. The concept of Dr. Zandman’s invention was sketched on a napkin using a ballpoint pen during a lunchtime conversation. This technology provides low ohmic resistance values from 0.0002 ohm to 1 ohm. These low values are predominantly used to measure changes in current flow or to divert current flow (known as Current Sensing or Shunting). A Power Metal Strip Resistor is constructed using a metal resistive element with terminals that are attached by welding, electroplating or cladding to opposite ends. The element consists of a metal strip which acts as the resistor body. The metal strip is thick enough without any ceramic substrate to withstand application and manufacturing environments Current Sensing Power Metal Strip Resistors can be used in various electronic systems, particularly high-current and high-power due to the combination of low ohmic resistance, low Temperature Coefficient of Resistance ("TCR") and low thermal Electro Magnetic Force ("EMF"). They allow control circuitry to monitor the level of current in a circuit by translating current into a voltage that can be easily measured. These devices achieve this by resisting the current flow in a circuit to a calibrated level which in turn allows any drop in voltage to be detected and monitored. This is again all due to the low resistance of these devices.
