Fixed inductors are components that store energy in the form of a magnetic field when electric current flows through them. They are commonly used in applications where a steady and constant-magnitude current is needed, such as power supplies and circuitry. The HCMA1707-4R7-R is a type of fixed inductor that is designed for use in DC-DC, RF, and general purpose switching power supplies.

The HCMA1707-4R7-R is a surface mount inductor with an operating temperature range from -40°C to +85°C and a storage temperature range from -55°C to +125°C. It is composed of an iron-powder toroidal core with a 4-layer winding construction, and has a maximum dc resistance of 4.7Ω, and a flux density of over 1.1T. The inductance range of the HCMA1707-4R7-R is from 4.5µH to 6.8µH, with a DC current rating of up to 10A. As a result, this type of inductor is well-suited for use in high current applications that require good power output/efficiency.

The HCMA1707-4R7-R is designed for use in applications that include voltage regulator circuits, power switching circuits, high frequency radio frequency (RF) filters, and various types of DC-DC converter circuits. In addition, the high inductance, low resistance, and low profile of the HCMA1707-4R7-R make it suitable for use in Low-EMI applications, where electromagnetic interference needs to be reduced.

The operation of the HCMA1707-4R7-R fixed inductor is based on Faraday\'s Law of Induction, which states that a voltage will be induced in a conductor whenever the surrounding magnetic field varies. In the case of a fixed inductor, such as the HCMA1707-4R7-R, a magnetic field is created when a current passes through the inductor windings. This magnetic field then interacts with the core of the inductor, inducing a voltage in the windings that opposes the change in the applied current. As a result, the inductor imparts a certain amount of impedance to the circuit, limiting the amount of current that can be transmitted and thus providing stable and reliable power supply.

The HCMA1707-4R7-R is a high-performance fixed inductor that is suitable for a variety of applications. It provides excellent efficiency and reliability due to its low resistance and high inductance, making it particularly appropriate for high current and low-EMI applications. In addition, due to its wide operating temperature range, it is well-suited for applications in harsh environments.
