Fixed inductors are passive electronic components that can produce a characteristic of inductance. These inductors have the most common name in the industry: coils, with a wide range of applications in low and high frequency circuits such as Oscillators, Mixers, Regulators, UPS, Phase-angle controllers, Filters and Transformers. PM125S-560M is a type of fixed inductor with excellent performance and stability, which is suitable for Bluetooth, Bluetooth low energy, Zigbee, WCDMA or CDMA related systems. It is one of the most popular fixed inductors on the market.

This PM125S-560M fixed inductor is constructed as a single-ended, shielded construction, where the inner-layer consists of a single layer of copper foil over an insulation layer for low capacitance and better coupling. It can withstand operating temperature of up to 105°C, and features a compact size, making it suitable for use in various applications. It also has excellent high frequency performance, with an inductance range up to 560nH, and a direct current rating of up to 125mA.

In terms of working principle, the PM125S-560M fixed inductor works only when a current flows through its winding. It then acts as a low-impedance path for the magnetic field generated by the alternating current. The field produced by the current flowing through the inductor causes magnetic flux to be generated and stored in the device, which induces a voltage in the winding. This voltage is called inductance voltage, and its magnitude is proportional to the current flow.

As the strength of the magnetic field produced by the device increases, the amount of voltage induced in the winding also increases, thus increasing its inductance. In effect, this inductor can “trap” energy and store it as magnetic flux, and when current flows in opposite direction, the inductor will release this stored energy as a voltage. This makes the device ideal for conditioning current in harmonic filters, EMI filters, and for controlling current or voltage in regulators or converters.

In terms of application field, the PM125S-560M fixed inductor is mainly used in the fields of communication, wireless communication, automotive, consumer electronics, LED lighting, etc. For example, its high Q value helps to reduce EMI interference in Bluetooth applications; its low DCR ensures maximum windings, and its high SRF helps to improve the stability of the circuit design. Additionally, its extremely low parasitic capacitance makes it suitable for high frequency applications, and its perfect temperature characteristics make it safe and reliable to use.

Overall, the PM125S-560M fixed inductor is a very versatile device, with many applications in various sectors and industries. With its excellent performance and stability, it is becoming increasingly popular among designers and engineers who need to build reliable and accurate electronic products. In addition, the device offers good protection against electromagnetic interference, making it an ideal choice for use in high frequency circuit designs.
