Fixed inductors refer to the inductors of which the inductance value is fixed and does not change with the change of frequency or other external parameters. These inductors are usually made in the form of coils and are used in a variety of applications. One such example is the HCMA1104-4R7-R fixed inductor.

The HCMA1104-4R7-R fixed inductor is a micro-sized inductor with a high power rating of up to three watts. It has a maximum inductance value of 4.7 mH and can work under temperatures ranging from -40°C to +125°C. This inductor is usually enclosed in a PPS resin encapsulated substrate, making it suitable for high temperature and high shock/vibration environments. It is also RoHS compliant and UL-listed.

The HCMA1104-4R7-R fixed inductor is mainly used in high-frequency switching power supplies, voltage regulator modules, and battery charging circuits. It is also used in automotive circuits and other consumer electronics applications. Its high power rating and excellent temperature performance make it an ideal choice for designers looking for power supplies with better efficiency.

The working principle of a fixed inductor relies on Faraday’s law of induction. According to Faraday’s law, an induced emf (electromotive force) is generated in a coil when the magnetic flux linking with the coil changes. This means that when a changing current passes through the coil’s wire windings, a voltage will be induced across the ends of the coil.

The HCMA1104-4R7-R fixed inductor utilizes this principle to generate a voltage across its leads when a current is passed through its windings. This voltage is essentially the voltage drop across the inductor, which can be used to regulate the current and ensure a steady flow of power to the connected circuitry. The inductance value of the inductor is based on the number of wire windings in the coil, the type of wire used, and the geometry of the coil.

In summary, the HCMA1104-4R7-R fixed inductor is an ideal choice for designers looking for a high power rated inductor for a variety of applications. Its PPS resin encapsulation ensures excellent temperature and vibration performance, making it suitable for use in automotive and consumer electronics applications. It utilizes Faraday’s law of induction to generate a voltage across its leads when a current is passed through its windings, thus helping to regulate the current and ensure a steady flow of power to the connected circuitry.
