Fixed inductors are inductive components that are not adjustable. Typical examples include Variable inductors, Potentiometer inductors, trimmer inductors, air core inductors, ferrite core inductors, iron core inductors, and so on. The 1782-67G series of inductors is one type of fixed inductor. It was designed as part of Molex’s Connectivity Solutions family of products.

The 1782-67G series is constructed with a metal alloy core, which is then surrounded by a molded polymer shell. This design enables it to generate higher inductance without the need for additional components. The core is also coated with a special insulation material on the inside and outside surfaces in order to reduce EMI and RFI. The outer shell also provides additional protection against physical damage and vibrations.

The main application field for the 1782-67G is in high speed switch-mode power supplies, such as those used in computers, telecommunications, and other electronic equipment. It is also well-suited for use in automotive applications, where it can help to reduce EMI interference in sensitive electronics. It can also be used in analog applications, such as audio filtering, for improved sound quality.

The working principle of the 1782-67G inductor is based on the conversion of electrical energy into a magnetic field. When an electrical current is passed through the metal core, it generates a magnetic field that induces an electric current in the surrounding shell. This induced current has the same frequency as the current that was passing through the core, but it is in the opposite direction. This creates a back EMF, or counter electro-motive force, that opposes the current flowing through the primary winding, resulting in the inductor behaving as a component with resistance.

The inductance of the 1782-67G can be changed by either adjusting the core material or by adjusting the size of the core. The size of the core is also directly related to the amount of inductance generated, so larger cores can generate more inductance. Additionally, the shape of the core can affect the overall inductance, such as when using a flat core for higher frequency applications or a wound core for lower frequency applications.

The 1782-67G is a versatile fixed inductor that can be used in a wide range of applications. Its metal alloy core provides excellent thermal and electrical performance, while its molded polymer shell provides additional protection against physical and vibration damage. Its adjustable core size and shape also allow for fine tuning of the inductance levels, making it a useful component for both high speed switch-mode power supplies and analog audio applications.
