Fixed inductors, such as the CEP12D38NP-1R8MC-H, are widely used in multiple applications, from controlling and regulating current in circuits to mitigating noise in power transmission systems. In this article, we will discuss the application field and working principle of the CEP12D38NP-1R8MC-H.

The CEP12D38NP-1R8MC-H is a molded-case, film-type, radial-lead fixed inductor, designed for surface mounting on printed circuit boards. It is part of the Common Mode Choke series, offering interference suppression capabilities suitable for low impedance line communications.

The extended range of CEP12D38NP-1R8MC-H fixed inductors provides a wide range of inductances from 0.5 μH to 47 μH at a rated current from 0.04 A to 3.2 A (according to UL and CSA safety requirements). The CEP12D38NP-1R8MC-H fixed inductors have a current rating of 1.8 A with a rated voltage of 1.2 Vrms at a temperature of 70°C.

The CEP12D38NP-1R8MC-H fixed inductors are primarily used in applications that require high stability and a high level of suppression of interference. It has a wide range of applications, including telecommunications, low-frequency power supplies, LED lighting, frequency margin control, audio, and video equipment.

The working principle of the CEP12D38NP-1R8MC-H fixed inductors is twofold. First, the inductor creates a magnetic field around the wire, the direction of which is vertical to the current flow. This field increases with the current in the winding, thereby inducing a voltage in the winding in proportion to the current. Second, the field has a retarding effect on current passing through the inductor, decreasing with frequency. This is important for preventing unwanted signal leakage, as higher frequencies tend to be more sensitive and difficult to suppress.

The CEP12D38NP-1R8MC-H fixed inductors offer reduced costs compared to traditional spiralled-wound inductors, operating reliably under the most demanding conditions. The additional benefits include improved coupled noise suppression, higher stability when exposed to high temperatures, and longer service life.

In conclusion, the CEP12D38NP-1R8MC-H fixed inductors are high-quality, multi-purpose inductors designed for multiple applications, from filtering to noise suppression. Their advantages such as high stability, temperature resistance, and long service life, make them ideal components for advanced electronic circuits.
