4494R-107

Fixed Inductors commonly know as coils are everywhere around us. They are used in a variety of applications ranging from power supplies, audio and RF applications to computers and communication systems. This article will examine the 4494R-107 application fields and its working principle.

Overview

The 4494R-107 is a radial leaded fixed inductor manufactured by Taiwan Semiconductor. It has a high temperature-resistant epoxy molded piece construction. It utilizes a high-end high-efficiency ferrite material and standard ferrite material cores. The 4494R-107 can handle up to 400VDC and 5A.

Application Field

The 4494R-107 is particularly well suited for applications with noise abatement requirements. This includes switching power supplies, DC/DC converters, servers, communication equipment, automobiles, and other situations.

The 4494R-107 is also suited for RFI/EMI suppression. It is suitable for use in cables, connectors, and other external equipment. It can help reduce interference from harmonics and high or low frequencies.

Working Principle

Fixed inductors work on the principle of Faraday\'s law of induction. According to Faraday\'s law, when a conductor is placed in a magnetic field, a current is induced in the conductor. The 4494R-107 works on this principle by using a coil of wire wound around a core, creating a magnetic field. When current is applied, the magnetic field induces a voltage. This voltage can be used to power circuits or devices.

The 4494R-107 also uses the principle of self-inductance. Self-inductance occurs when current flowing through a coil creates a magnetic field that opposes the current. This magnetic field induces a voltage that is proportional to the self-inductance value of the coil. The 4494R-107 has a self-inductance value of 7.9nH.

Conclusion

The 4494R-107 is a high-temperature, high-efficiency fixed inductor. It has an operating temperature range of -55°C to 125°C, making it suitable for a variety of applications. It utilizes the principles of Faraday\'s law of induction and self-inductance to induce a voltage when current is applied.
