SDR1307-330KL Inductors, Coils, Chokes

Fixed inductors, also called fixed-value inductors, are widely used in various electronic circuits. The SDR1307-330KL belongs to this type of inductors. It is based on a complex spiral ferrite core, which can be used as a power source filter, anti-interference device or energy storage device.

The SDR1307-330KL has a larger inductance than normal inductors, and has higher line stability and stronger anti-interference ability. The inductance is 330mH at 80mA. Its rated current is 2A, and the rated temperature is 70 Celsius, with a Series resistance of 0.65Ω. With such excellent characteristics, it is widely used in various fields, such as millisecond timing, oscillation, high-frequency blur filter interface, digital circuit control, and various audio applications.

In terms of its working principle, when the SDR1307-330KL is connected to a dc power source, a magnitude of current will flow through the coils. This current will generate a magnetic field in the ferrite core, which will induce a voltage in the electrical windings. This voltage will be in phase with the current, creating a self-induced voltage effect, that is, a distributed voltage is generated in the windings due to its resistance characteristics. As the current flowing through the coil changes, the self-induced voltage generated will also vary proportionally.

The SDR1307-330KL is mainly used in motor control circuits, anti-interference circuits, noise removal circuits, power switching circuits and DC-DC converters. In motor control circuits, it is used to form an essentially constant current source; in the anti-interference circuits, it can form a high-frequency attenuation loop; in the noise removal circuit, it can form an RC low-pass filter; and in the DC-DC converter, the SDR1307-330KL can also perform frequency conversion and do many other kinds of rectifier related works.

In conclusion, the SDR1307-330KL is a high-performance, fixed-value inductor with high stability and excellent anti-interference ability. Its applications include motor control circuits, anti-interference circuits, noise removal circuits, power switching circuits, DC-DC converters and various audio applications. Its working principle is based on the self-induced voltage effect created when the inductor is exposed to a changing current.
