Fixed inductors are essentially discrete components designed to be used in electronic circuits for the purpose of storing energy or modulating current. Specifically, the SCRH127-181 is a surface mountable, two-layer ceramic inductor that effectively bridges the gap between small-sized ferrite cores and large air-core coils.

The SCRH127-181 inductor is capable of storing up to a maximum of 180uH with a 4.7Ω DC resistance. It is suitable for both high-frequency switching and low-frequency applications, and is rated from 10A to 120A with low inserted loss and excellent EMI suppression thanks to its two-layer construction.

The SCRH127-181 inductor is constructed with two ceramic plates, both of which are embedded with inductive windings and a ferrite core. Magnetic materials, such as ferrite, are used to create an inductive field which is responsible for the storing of energy. The two ceramic plates act as shielding plates to reduce electromagnetic interference, while prevent the buildup of excess heat. The ferrite core helps to improve the inductor’s overall performance, particularly at higher frequencies.

The inductor’s working principle can be explained by means of Faraday’s Law of Induction, which states that an induced current will be generated in a circuit whenever there is a change in the circuit’s magnetic flux. In the case of the SCRH127-181, when an AC or DC current is applied to the inductor, the ferrite core is subjected to a change in magnetic flux, thus inducing a small current which is stored in the two ceramic plates.

The SCRH127-181 can be used in a wide range of applications, including power supplies, switching circuits, frequency control circuits, and sensors. It is particularly useful for applications that require high levels of inductance at low power levels such as wireless charging coils. Additionally, these inductors are capable of operating from -40°C to +125°C, making them suitable for use in harsh environmental conditions.

In conclusion, the SCRH127-181 is a highly versatile surface mountable two-layer ceramic inductor that is suitable for a wide range of applications including power supplies, switching circuits, and frequency control circuits. It has a maximum inductance of 180uH and uses a ferrite core for enhanced performance at higher frequencies, with low insertion loss and excellent EMI suppression. For these reasons, the SCRH127-181 inductor is an excellent choice for those looking to use a high-performance and reliable inductor.
