Fixed inductors, also known as chokes, coils,isolated coils, and reactors, are fundamental components used in radio frequency (RF) and power electronics applications. The CDH53NP-560KC is a common fixed inductor used in these applications. This device is composed of a wound-wire coil,a core, and a shield case.

CDH53NP-560KC Application Field

The CDH53NP-560KC is used mainly in the following applications:

• Electronics circuits such as power supplies, DC-DC and AC-DC converters where it is connected in series or parallel depending on the application.
• Vibration damping devices, which help improve system reliability.
• Electronic resonance filters for power supplies.
• RF receiver-filters for a range of frequency bands.

CDH53NP-560KC Working Principle

The CDH53NP-560KC is composed of a wound wire coil, a core, and a shield case. In its operation, the coil serves as the conductive element and the core as the magnetic material to store the magnetic field formed by the windings. The core also provides electrical isolation, reducing coupling between adjacent windings.

When connected to a power source, a current flows through the windings which creates an alternating magnetic field that induces voltage in the windings, effectively increasing the current. This is known as inductance. The core also stores the energy from the magnetic field, enabling it to be used when needed. When the current is shut off, the energy stored in the core is released back into the windings.

The shield case serves two functions. First, it prevents any electrical interference from entering the inductor. This is important because any external noise or interference can affect the performance of the device. Second, the shield acts as a Faraday cage, shielding the internal electrical components from outside interference.

Conclusion

The CDH53NP-560KC is a popular fixed inductor used in electronics and RF applications such as power supplies, DC-DC and AC-DC converters, vibration damping, resonance filters, and RF receiver-filters. The device consists of a wound-wire coil, a core, and a shield case that provide inductance and energy storage, isolation for windings, and electromagnetic interference protection respectively.
