Fixed inductors

Fixed inductors are key components in the production of electricity devices such as radios, televisions, personal computers (PCs), and other electronic equipment. Their use is especially crucial in low-voltage applications such as in cars, providing a steady current for the engine to run. Their resistance to sudden changes in currents prevents them from shorting out or weakening over time.

The CPL2512TR47M is a ceramic-coated surface-mounted fixed inductor manufactured by TDK Corporation. It is a component specifically designed to generate and maintain a specific inductance and to handle high- frequencies. The device has two basic functions, one is the inductance being generated and maintained and the other is the high-frequency filtering.

Application field and Working Principle

The CPL2512TR47M can be applied in filters, timing circuits, oscillators, and RF circuits. Its main application is in impedance matching for antennas in short-range wireless communication systems, such as local area networks, Bluetooth, and Wifi. It can also be used in power supplies to help regulate the AC output and to reduce ripple current.

The CPL2512TR47M is a high frequency device with high efficiency. It has two windings, a primary winding and a secondary winding, separated by a layer of insulation material. The primary winding obtains electrical power from an external source and sends it to the secondary winding. A magnet is placed in between the two windings, and a conductor is placed in the magnetic field between them. The primary winding is oscillating with the magnetic field, and this generates an ac current in the secondary winding. These two currents form a steady-state inductance, allowing for high efficiency filtering of ac/dc power.

The CPL2512TR47M also uses a ceramic casing which helps prevent the inductor from vibrating and generating noise. The inductor has a maximum working temperature of 125°C and a dielectric withstand voltage of 200 volts. The device has a tracking error of 5% and a frequency range of 9kHz to 500kHz. It has a low insertion loss and high power handling capability, making it ideal for use in low-power applications.

The CPL2512TR47M is a reliable and efficient device suitable for a range of applications. It is well-suited to high-frequency systems where maintaining consistency in inductance is important. With its high efficiency and superior filtering, this component is an invaluable part of any electronic circuit.
