Fixed inductors are one of the basic components on every printed circuit board. A fixed inductor, also known as a choke or coil, is an electronic component which helps regulate the amount of current passing through a circuit. The type of inductor used depends on the frequency range and current it is intended to block. In the case of a high frequency signal, which requires more control, a larger and more expensive inductor is used. PM1812-120J fixed inductor is an example of such an application.

The PM1812-120J fixed inductor is a radial device designed to meet the high-performance requirements of sophisticated electrical circuits, such as automotive, medical, military, consumer, and other industrial applications. It has an inductance of 0.11μH with a rated current of 1.2A. This versatile inductor is rated at a temperature range of -55°C to 155°C and is also RoHS compliant. The PM1812-120J has a low profile and a high value of saturation before it reaches saturation cutoff. It is also capable of providing a low DCR, and ensures good temperature stability.

By itself, an inductor has relatively few applications. However, when combined with other components like resistors and capacitors, it opens up a host of possibilities. Its primary application is filtering or blocking high frequency signals from getting into the rest of the circuit. This helps reduce the level of interference and noise that can be caused by signals in the surrounding environment. It also helps to regulate the current and voltage in a circuit, and can be used to create a stable voltage supply for the device.

The working principle of the PM1812-120J fixed inductor is simple. It works on the principle of electromagnetic induction. When current passes through the winding of the inductor, it creates a magnetic field which is in opposition to the current producing a back EMF, or counter EMF. This counter EMF opposes any changes in the current and prevents the flow of any unwanted high frequency signals.

The PM1812-120J fixed inductor is widely used in various types of circuits due to its versatile size and performance features. Its most common uses are in DC-DC converters, brushless DC motors, switching regulators, and filter circuits. It is also commonly used for noise suppression and voltage regulation in small appliances, such as cell phones, electronic toys, and digital cameras.

In conclusion, the PM1812-120J fixed inductor is an excellent choice for any circuit design requiring a reliable performance and long-term durability. Its versatility and cost-effectiveness make it an ideal inductor for a wide range of applications. Its ability to suppress high frequency signals and regulate current and voltage ensures that any circuit using it will perform as expected.
