Fixed inductors come in a variety of shapes and sizes, and the 1638-04H is one such component. Also known as a ceramic core inductor, it is a small, epoxy-packaged device designed to store energy in the form of inductance and thereby provide electrical current control and signal filtering. Originally developed for use in the oscilloscope industry, ceramic core inductors have become widely recognized due to their broad range of applications in modern electronics.

The 1638-04H specifically features copper-clad (coated) terminals, an encapsulated construction, and a construction style that guarantees a rugged performance. It has 4-terminal, epoxy encased package and the core material is high-quality ceramic. Its elongated rectangular shape ensures a higher rate of prevalence of electric and magnetic fields. It also features a planar design for higher tolerance and increased space savings. This inductor has an inductance range of 0.4 - 5.3 μH (micro henries) and a maximum DC current of 2 Amps.

The 1638-04H\'s application fields mainly include use in switch-mode power supplies, output filtering, pocket-form radios, color television sets, power conditioning, and audio amplifiers. As its current rating is relatively low, it is mainly used in low-power electronic circuits.

In terms of working principle, the 1638-04H acts as a current limiter. This means that it can limit the current flowing through itself, resisting any changes in the current value. When the current run through the inductor reaches a certain level, the voltage across the inductor increases very quickly, reaching a saturation level. This then allows the inductor to limit the amount of current flowing through it, thus protecting other components in the circuit. The higher the inductance of the component, the higher the protection it offers.

The 1638-04H ceramic core inductor offers excellent signal filtering, and its compact and rugged design allows it to be used in a variety of applications. Its 4-terminal construction and planar design make it even more advantageous for use in modern electronic applications. With its moderate inductance range, this component can be used to accurately control electrical current, making it a perfect choice for applications where high accuracy is required. In addition, its ceramic core construction allows it to maintain its inductance under a variety of operating conditions, and thereby guarantee excellent performance.
