Fixed Inductors

Inductors, also known as coils, are electronic components consisting of a conductor, such as a wire, that is wound around a core material. They have the ability to store energy in the form of a magnetic field, also called inductance. The unit of measure for inductance is the henry. Fixed inductors have several applications in electronics in both analog and digital circuits, and are available in a variety of sizes and shapes. The CAL45TB392K is one of many fixed inductors.

CAL45TB392K Application Field

The CAL45TB392K is a type-2 fixed inductor, grouped with other components that exhibit great stability when exposed to vibration or shock. It can be used for resonance, high frequency applications, current sensing, DC–DC converters for power supplies, or as chokes to help filter out RF noise in wireless applications. The CAL45TB392K has a wide operation temperature range, providing high reliability even at the highest temperatures.

CAL45TB392K Working Principle

The CAL45TB392K has a construction with two winding layers, each layer composed of two separate coils. As current passes through the inner coil, a magnetic field is generated around it. When the current passes through the outer coil, the magnetic field induces a reverse current in the outer coil, creating an electromagnetic coupling between the two coils.

The current in the inner coil generates a current in the outer coil, causing the current in the inner coil to be amplified. This amplification is referred to as inductance. The outer coil is usually wound with thicker wire than the inner layer, which increases the coupling and induces a higher inductance. This is the working principle of the CAL45TB392K.

Conclusion

Inductors, also known as fixed coils, are used in many applications and come in a variety of sizes and shapes. The CAL45TB392K is a type-2 fixed inductor, used for resonance, high frequency applications, current sensing, DC–DC converters, and chokes for noise filtering. It has a two-layer construction, amplifying the current in the inner coil due to electromagnetic coupling and its high inductance.
