Fixed Inductors

Inductors are passive electronic components that are used in electrical circuits to store energy in the form of magnetic fields. They are commonly found in circuits that have oscillating or alternating current. Fixed Inductors are a type of inductor whose inductance value is fixed, and does not change with frequency or applied voltage. Fixed inductors are given the designation letter "L”.

One example of a fixed inductor is the PG0085.152NL. This type of inductor is a surface mount, non-polarized device with an inductance of 152 nH. The PG0085.152NL has a current rating of 1 A, a saturation current of 1.2 A, and an operating temperature range from -40°C to +105°C.

The primary function of a fixed inductor is to create a magnetic field in a fixed amount when a current is applied. This magnetic field will in turn induce a voltage in the inductor. This voltage will oppose any change in the current that created the field. This is known as the inductor\'s inductive reactance, and is represented in an equation as XL = 2πfL, where f is the frequency of the inducing current, and L is the value of the inductor in Henries.

In a fixed inductor, this inductive reactance is independent of frequency and voltage, the value of XL being only dependent on the value of L. A fixed inductor is what is known as a low pass filter, since signals of high frequency are blocked by their high inductive reactance.

Fixed inductors come in various shapes and sizes, from tiny surface mount devices to cylindrical Tubular Inductors. Depending on the application, fixed inductors can be used to create filters, oscillators, matching networks, and delay lines. They may also be used in crossover networks in speaker systems, as transformers, and for DC line conditioning.

The PG0085.152NL is a small, space-saving inductor designed for use in surface mount applications. Its small size, good heat dissipation characteristics, and high saturation current make it ideal for use in low-power, low-voltage circuits. It is commonly used in mobile phone circuits, switch mode power supplies, and low-noise audio circuits.

In conclusion, the fixed inductor, such as the PG0085.152NL is a versatile, reliable component that can be used in a wide range of electrical and electronic circuits. It is designed to maintain a fixed inductance value regardless of frequency or applied voltage, and is ideal for use in low noise circuits that require small size and good heat dissipation.
