Fixed Inductors

Fixed inductors provide a relatively simple and cost-effective solution for various applications such as filtering, signal conditioning, and high-frequency circuits. They come in many forms and sizes, ranging from surface-mount through-hole components to large 5H air-core coils. One of the largest types of inductors currently in use is the 0819-16K.

0819-16K Application Field

The 0819-16K inductor is primarily used in power supplies and audio circuits. It is popular for its large size and ability to handle high power levels, up to 20A. It is commonly used in parallel configurations, connected to a large number of other components to form a power network. In some cases, it can also be used in switching circuits or as a feedback element in a tone or signal circuit. When used in audio circuits, the 0819-16K typically provides a low-resonance, high-impedance environment.

0819-16K Working Principle

The 0819-16K works on the principle of an inductor, which is a conductive loop, or "coil," of wire through which an electrical current can flow. The number of coils affects the inductance of the device; the more coils, the more inductance. The inductance of the 0819-16K is very high, up to 16,000 μH, or 16 millihenries. The electromagnetic field created by a coil will oppose a change in current. This is known as inductance. In the case of the 0819-16K, the high inductance means that when current is applied, the amount of opposition will be much stronger, resulting in a lower voltage across the inductor. This is why the 0819-16K is used to control large currents in power supplies. The 0819-16K is also often used in audio circuits due to its low coil resistance, which provides a low-resonance environment. In addition, its high inductance makes it effective in filtering out any unwanted noise or interference from other components in the audio system.

Conclusion

The 0819-16K inductor is a versatile component, capable of handling high power levels in power supplies, as well as providing a low-resonance environment in audio circuits. Its large size and high inductance makes it a suitable choice for many applications, from filter systems to signal conditioning and high-frequency circuits.
