2256-18K Application Field and Working Principle

The 2256-18K is a common type of fixed inductor for various electronic applications. It is available in four styles with various size configurations and a wide range of inductance values. The 2256-18K is widely used in industrial, commercial, consumer, aerospace and medical applications.

Basic Construction

The 2256-18K consists of a ferrite slug containing two winding coils with wire connected to the external pins for electrical connection. The core of the inductor is made of a high-grade ferrite material having superior magnetic properties. The cores are encapsulated in an epoxy potting material for superior thermal and physical protection.

Working Principle

The 2256-18K fixed inductor works according to the principle of self-induction. When an electric current flows through the inductor, it induces a counter-emf in the opposite direction, which opposes the flow of current. This phenomenon is called self-induction. The magnitude of the counter-emf is directly proportional to the rate of change of the current flowing through the inductor. Thus, in the 2256-18K, the amount of induced voltage is proportional to the rate of change of the current and this, in turn, changes its value of inductance.
