Fixed Inductors: A Primer on the PT300-1200HM Application Field and Working Principle

Fixed inductors are basic components used in many electronic circuits, and they come in countless designs and forms based on the manufacturer or application. The PT300-1200HM is one such inductor – an SMD power inductor produced by Pulse Electronics. Its convenient size makes it suitable for many applications, and its numerous other technical characteristics make it a preferred choice when it comes to power inductors.

The PT300-1200HM inductors are commonly used in applications ranging from DC-DC converters and LED drivers to general power supplies, charger controllers, and computers. They are capable of handling loads up to 4.2A, with a saturation current of 7.5A and an inductance of 8.2µH. The PT300-1200HM is also well-suited for power supplies in consumer electronics, ensuring they stay within the desired voltage range at all times.

Since the PT300-1200HM is a switch mode power inductor, it naturally has many advantages over conventional inductors. As the name implies, it allows the inductor to switch from a low- to a high-current state quickly; this is possible because the inductor is equipped with a fast switching diode, allowing it to adjust to changing inputs with ease. Additionally, it is designed to have a low insertion loss, minimizing the wasted energy that is common with other types of inductors.

The working principle of the PT300-1200HM is relatively simple. As current passes through the winding of the inductor, it induces a magnetic field that opposes the current. This causes some of the current to be “stored” in the inductor in the form of a magnetic field, allowing the inductor to act as an energy regulator. This effectively reduces the amount of current going through the inductor in a given application, helping to ensure that the electrical supply is maintained at a constant level.

Besides its performance, the PT300-1200HM also has some impressive technical specifications. It has a max frequency of 1MHz, an operating temperature of -40°C to +85°C, and a dielectric strength of 1000V. The inductor also comes in a RoHS-compliant package and is lead-free, making it a safe and reliable choice for customer products.

Overall, the PT300-1200HM is an excellent choice for any application that requires an efficient and reliable power inductor. Its robust construction and design make it a reliable component in any circuit, while its technical specifications and performance provide a great deal of versatility. The PT300-1200HM is a great example of what modern inductors have to offer – efficiency, durability, and reliability at a reasonable price.
