HTR Audiograde "Non-Inductive" wirewound Resistors
A wire wound resistor is an electrical passive component that limits current. The resistive element exists out of an insulated metallic wire that is winded around a core of non-conductive material. The wire material has a high resistivity, and is usually made of an alloy such as Nickel-chromium (Nichrome) or a copper-nickel-manganese alloy called Manganin. Common core materials include ceramic, plastic and glass. Wire wound resistors are the oldest type of resistors that are still manufactured today.
What Makes A wirewound Resistor "AUDIOGRADE"
Wire wound resistors naturally have some capacitance and inductance. Because of this, they influence the current flow in an alternating current circuit. This effect is usually not wanted.To Minimize this Various winding Techniques are used of which The Ayrton-perry Winding is considered to be the best.
What Is Ayrton-Perry Winding?
Ayrton-Perry winding is a type of bifilar winding pattern used in winding wire on forms to make electronic components. Its advantage is that the resulting coil of wire has low values of parasitic inductance and parasitic capacitance.Ayrton-Perry windings of resistance wire are used to make wirewound RF resistors that are used at high frequencies, where inductance and capacitance are unwanted.
The winding is made of two separate wires wound in opposing directions along an insulating form and connected in parallel at the ends. Since there are the same number of turns of wire in either direction, the magnetic fields of the two wires cancel each other out, so the coil has little inductance; and since adjacent turns of the two wires are at approximately the same voltage, there is little parasitic capacitance between the turns.
