Fixed inductors are components that deliver an inductance value in a range predetermined by the manufacturer, and they’re utilized in a broad selection of applications. Whether used in regulated power supplies or as RF chokes, fixed inductors must fulfill certain criteria and their design and construction must be suitable for that application.

The SRP4020-4R3M is a fixed inductor from the SRP4020 series. This series consists of several surface mount devices with inductance, Q, and SRF values suitable for various applications. The SRP4020-4R3M, in particular, is rated for operation at a maximum temperature of +125°C and an inductance value of 4.3 mH ±20%. The SRF is 250 MHz, and the Q is 17.

The SRP4020-4R3M is designed for use in switching DC/DC converters, switchmode power supplies, and other similar applications. It is constructed of high-permittivity material to ensure high inductance. It is also capable of withstanding high frequency switching and allowing for high ripple current due to low DCR. Furthermore, the SRP4020-4R3M features an SMT package that is suitable for automated assembly.

The operating principle of the SRP4020-4R3M is based on the principles of inductance. When electrical current passes through a conductor, it induces a magnetic flux in the inductor’s core. The amount of inductance is determined by the construction of the inductor and the material used in its construction. The SRP4020-4R3M is made of high-permittivity material, giving it a high inductance rating, excellent performance, and high temperature operation.

The SRP4020-4R3M is also designed to provide low ESR and DCR ratings. This is achieved due to the combination of an optimized core and the use of advanced materials in the construction. This ensures that the inductor is able to provide a high level of performance and low losses even when operating at high frequencies and temperatures.

In conclusion, the SRP4020-4R3M is an ideal choice for applications which require an inductor with high inductance, excellent performance, and high temperature operation. It is also suitable for use in switchmode power supplies, DC/DC converters, and other similar applications due to its low ESR and DCR ratings. By utilizing a combination of high-permittivity material and an optimized core structure, the SRP4020-4R3M is able to provide excellent performance and operation in a wide range of applications.
