Fixed inductors are components used in electronic circuits to store energy in the form of magnetic fields. They are used to provide a current or voltage at a particular frequency or phase angle, which is necessary for the operation of many electronic circuits. They can be found in nearly all types of electronic equipment, including electrical motors, radio receivers, cell phones, digital cameras, and more.

The PM125SH-391M-RC is a type of fixed inductor. It is constructed with a combination of ceramic core and pure copper wire to create a high-frequency toroidal inductor with a low profile. The PM125SH-391M-RC is particularly suitable for RF applications such as smart meters, Wi-Fi, Bluetooth, and power communications.

The PM125SH-391M-RC consists of two parts: an inductor and a capacitor. The coil is a 5.4 mH inductor, measuring 5.45mm x 4.60mm. The capacitor is a 0.033μF ceramic capacitor, which is particularly used for high-frequency applications. The combination of these components provides a suitable frequency and output voltage level for the application.

The main working principle of the PM125SH-391M-RC is based on the same principle as a transformer coil. When a current is passed through the coil, it induces a magnetic field that produces an induced voltage in the neighboring capacitor. This helps to build a circuit, as the electric potential is able to flow between components.

In terms of performance, the PM125SH-391M-RC performs optimally at a high-frequency, with a maximum operating frequency of up to 1.3GHz. It is also able to withstand high temperature fluctuations, having a working temperature range of -55℃ to +125℃. The PM125SH-391M-RC has an approximate self-resonant frequency of approximately 1GHz and a maximum DCR of 17.4 mΩ.

Overall, the PM125SH-391M-RC is suitable for a range of applications, most notably those requiring a high-frequency response, such as RF communication and miniaturized smart meters. It is constructed with ceramic core and pure copper wire, which makes it small and efficient. Additionally, the PM125SH-391M-RC performs optimally at a high-frequency, making it an ideal choice for many RF applications.
