SL1923-222KR70-PF

Fixed inductors are used in numerous electronic applications, such as power supplies, motor drives, and telecommunications equipment. The SL1923-222KR70-PF is a popular high-current, high-voltage fixed inductor typically used in power supply designs.

The SL1923-222KR70-PF is a shielded, high-current, high-voltage fixed inductor that offers exceptionally low magnetic flux leakage. It is designed for environments requiring high levels of electromagnetic interference (EMI) shielding, operating at temperatures up to 85°C. This fixed inductor is available with a variety of inductance values ranging from 2.2µH to 47µH.

The SL1923-222KR70-PF has a wide range of applications. It can be used in applications such as switching power supplies, DC/DC converters, motor and lighting applications, power factor correction, and voltage step-up/down converters. It is also suitable for applications such as AC inverters, laptop charging circuits, and LED drivers.

The working principle of the SL1923-222KR70-PF is based on Faraday\'s Law of Induction. Faraday\'s Law states that a changing magnetic field causes an induced electromotive force (EMF) in a nearby closed loop, per the formula EMF= N - (dΦ/dt), where N is the number of turns in the inductor and dΦ/dt is the rate of change of magnetic flux through the inductor. The SL1923-222KR70-PF exploits this principle in order to create an electromagnetic field for the purpose of storing energy.

The stored energy in the SL1923-222KR70-PF is proportional to the current passing through it and is discharged when the current decreases. During the discharge, the electromagnetic field collapses and induces an opposite EMF in the inductor. This induced EMF opposes the change in the current and produces an electromotive force proportional to the rate of change of the current.

The SL1923-222KR70-PF is an efficient fixed inductor capable of delivering high currents with comparatively low losses. The low magnetic flux leakage enables high efficiency in applications where EMI shielding is required. Its wide application range and high energy storage capability makes it an ideal choice for a variety of power supply designs.
