Element / Shunt Element resistors, or Shunts, are produced using a solid piece of resistance material. Depending on the material chosen, these resistors can yield great stability in very low values. This stability can be difficult to achieve in other constructions at such low values DESCRIPTION: The LOB Series power precision metal element resistors feature resistance values down to 0.005 with virtually no inductance. Available in 1, 3, and 5 watt rated axial leaded packages, these resistors are compatible with automatic insertion equipment
Metal film resistors are usually made of Nichrome, but also other materials such as tantalum nitride is used. The resistive film is printed on a cylindrical or flat insulating substrate. The resistive material is a combination of a Ceramic material and a Metal, and therefore these resistors are also referred to as Cermet . Often, the thicker the metal film deposited, the more stable the resistor value. Typically film thicknesses between 50 and 250nm are used as material thicknesses in this region tend to provide a greater long term stability level
PWR4412-2S Series — Bare Metal Element Resistor The PWR4412-2S Series is a through hole resistor designed for current shunt and current sensing applications such as power supplies of different kinds, motor drives and man Film Resistors In a film resistor, the resistive material is a very thin coating of carbon or metal on an insulating substrate, such as ceramic or glass. The value of the resistance is determined by the thickness of the film and the amount of carbon or metal in it. These resistors are available with very accurate and stable values Designated the OAR Series, these open-air through-hole devices consist of a custom-engineered resistive element welded to copper leads with integral stand-offs from the PC board. Copper leads minimize the resistance shift caused by solder wicking, which often occurs with single alloy resistors when excess solder forms on the base of the resistor
