Fixed inductors have long been essential parts of many different electronic designs, including those that are used in power supplies, low noise circuits, converters, and signal processors. The SP1210-392K is one such inductor, and its application field and working principle is explained in more detail below.

Application Field

The SP1210-392K fixed inductor is a fixed, center-tapped choke coil, designed for use in applications such as electrostatic shielding, EMI/RFI noise suppression, line filtering, and radiation-resistant applications. It has a rated voltage up to 400 VDC, a resistance of 392 mΩ, and an inductance of 4.7 µH. The rated current is up to 12 A, with a maximum DC current of 16 A. The SP1210-392K is suitable for use over a large temperature range between -55 to +105°C (-67 to + 221°F).

Working Principle

The SP1210-392K inductor works by creating a magnetic field around the coil which stores energy in that field. When a current is passed through the coil, the magnetic field is created, and the stored energy is released as the circuit is disconnected. The inductivity of the coil determines how much energy is released, and this influences the voltage level of the signal.

For the SP1210-392K, the inductance is 4.7 µH, meaning that it will store energy allowing for a voltage level of up to 400 VDC. The current being used in the circuit also affects the output voltage of the signal, with higher currents resulting in higher voltages. Additionally, the SP1210-392K has a resistance of 392 mΩ, meaning that it will not draw a large current and so the maximum current should be kept in check when connecting it to a circuit.

Overall

The SP1210-392K fixed inductor is suitable for use in various applications, including electrostatic shielding, EMI/RFI noise suppression, line filtering, and radiation-resistant applications. Its inductivity is 4.7 µH allowing for up to 400 VDC voltage. Additionally, the resistance of 392 mΩ should be kept in mind when connecting the SP1210-392K to a circuit in order to prevent any excess current from being drawn.
