Fixed inductors find a variety of uses in electronics ranging from loudspeaker cross-over networks to RF chokes for blocking unwanted signals. The 160-181HS series inductors are a good example of this, with an extended range of application fields being provided by their higher power rating. This article will look at these applications in more detail, as well as discussing their typical working principles.

The 160-181HS series inductors are available in a range of sizes, from 10mH to 500mH, with a wide selection of current ratings up to 11.5A. These are ideal for use in a number of different applications, ranging from EMI suppression in consumer electronics to power supply decoupling in industrial applications. The robust construction makes them suitable for use in a wide variety of environments, including those subject to high temperatures or humidity.

When incorporated into a circuit, the 160-181HS series inductors act to increase the inductance of the circuit. This is achieved by introducing an additional inductor in parallel with the existing circuit. This has the effect of increasing the impedance of the total circuit, allowing it to block some of the unwanted frequency components present in the circuit. This helps to reduce crosstalk, EMI, and to limit the amount of power dissipated in the circuit.

The working principle of an inductor is relatively straightforward. An inductor is composed of a coil of wire which, when subjected to a changing current, produces a magnetic field. This field then induces a voltage across the coil, which opposes the current flow. This voltage drop across the inductor varies with the rate of change of the current, with a large voltage drop being produced when the current changes rapidly. This voltage is used to control the current flow in the circuit and to block some of the unwanted frequency components present in the circuit.

In addition to their use in EMI suppression, 160-181HS series inductors are also used for power supply decoupling. Decoupling is the process of blocking unwanted signals from passing between two circuits, allowing them to operate independently. This is achieved by introducing an inductor in series with the circuit, the inductor acting to block any unwanted signals from passing between the circuits. This helps to reduce the amount of power dissipated in the circuit, as well as providing a level of protection should any of the circuits be exposed to voltage transients.

The 160-181HS series inductors also find use in loudspeaker cross-over networks. Cross-over networks are used to separate the frequencies of a signal, allowing higher and lower frequencies to be sent to separate drivers. The inductors act to block some of the higher frequencies from passing to the lower frequency drivers, improving the overall sound quality of the system. The inductors also help to protect the drivers from overload, as the inductance ensures that the current in the driver is reduced when it is operated at higher power levels.

In conclusion, the 160-181HS series inductors are a versatile and robust range of inductors, suitable for use in a variety of different applications. The higher power rating makes them particularly suited to EMI suppression and power supply decoupling, as well as for use in loudspeaker cross-over networks. Their common working principle is relatively straightforward, relying on the generation of a magnetic field that induces a voltage across the inductor, producing a voltage drop that is used to control the current flow in the circuit.
