Fixed Inductors

Fixed inductors are electrical components with a fixed value of inductance that do not change over the operating range of the device. The MILP1812-104K is a fixed-inductance device which is suitable for applications in various fields. This article will discuss the application field and working principle of the MILP1812-104K.

Application Field

The MILP1812-104K is designed for use in many types of applications ranging from DC/DC power converters and filtering to RF amplifiers. The MILP1812-104K features low current flow and has a wide frequency range which makes it suitable for use in many different power applications. Due to its low ESR (equivalent series resistance) and high quality factor ratings, the MILP1812-104K is also suitable for use in RF amplifiers. Additionally, the MILP1812-104K has a wide temperature range of -55°C to +150°C which makes it suitable for a range of applications.

Working Principle

The MILP1812-104K is a fixed, single layer choke coil which works on the principle of inductance. Inductance is a property of an electric conductor or device which opposes the change of the current passing through the conductor. The MILP1812-104K is designed to maintain a constant inductance over a wide range of frequencies, and thus has the ability to filter high frequency noise while allowing low frequency signals to pass.The MILP1812-104K features a single core construction which is very efficient in terms of construction and operation. The single core limits the capacitive coupling between windings, ensuring maximum inductance levels are maintained. The MILP1812-104K also features a magnetic shield which helps reduce much of the electro-magnetic interference (EMI) which can occur.

Conclusion

The MILP1812-104K is a fixed inductance device which is suitable for applications in various fields, including DC/DC power converters, filtering, and RF amplifiers. The MILP1812-104K features a single core construction which helps to reduce capacitive coupling and increase inductance. Additionally, the MILP1812-104K features a magnetic shield and has a wide temperature range. These features make the MILP1812-104K an ideal choice for use in many power applications.
