Fixed Inductors

Inductors are electronic components designed to store energy in the form of a magnetic field. They are widely used to filter out high-frequency noise signals or to create low-pass, band-pass or notch filters. For radio frequency applications, inductors can be used as either series or parallel tuned LC circuits. One type of inductor, referred to as a fixed inductor, is a non-adjustable and non-tunable component with a constant inductance. A fixed inductor is one of the simplest types of inductors and consists of a coil of wire wound around a core material that enhances the magnetic effect.

PA4318.473NLT application field and working principle

The PA4318.473NLT fixed inductor is one of the most commonly used inductors for basic low frequency and switching regulator applications. This inductor features a minimum resistance and thermally stable winding. It is small and lightweight, making it suitable for use in high density printed circuit boards. The inductance is fixed at 4.73 µH, and the rated current is 1.41 A. The inductor is constructed using an iron-powdered core for high-frequency application. It features low winding resistance, which increases the efficiency of the circuit. This device can be used in applications that require a stable battery voltage or low ripple current. The working principle of the PA4318.473NLT fixed inductor is quite simple. When an alternating current is applied to the inductor, it creates a magnetic field in the core material. This magnetic field then induces an electromotive force, which is then outputted back into the circuit. The magnitude of the current in the inductor is then determined by the amount of inductance presented in the core material.The frequency range in which the device operates is from DC to 500kHz. The device has a maximum rated temperature of 105°C and an insulation resistance of 1,000MΩ. Its rated peak surge current is 60A for 10µs. The device comes in an SMA surface mount package which allows for mechanical stability and protection from harsh environmental conditions. The PA4318.473NLT fixed inductor is used primarily for low frequency and low ripple current applications. It can be used in film capacitor networks, power transformers, motor drivers, control circuits, and switching regulator circuits. The inductor can also be used to provide input and output impedance matching in wireless network systems, which helps to increase the efficiency of the system and reduce crosstalk. In addition, the inductor can be used to create anti-aliasing filters in audio amplifiers or to increase power factor correction in AC/DC power supplies. The PA4318.473NLT fixed inductor is ideal for low frequency applications due to its fixed inductance value. Its small size and lightweight construction make it ideal for use in high density printed circuit boards, and its low wind resistance increases the efficiency of the circuit. The device is rated to work within a wide frequency range and is also suitable for harsh environmental applications.
