Fixed Inductors have a wide range of uses in industry and electronics. The SP1008-123H is one such example of a fixed inductor. This article will take a look at the application field and working principle of the SP1008-123H.

Applications

The SP1008-123H has a variety of applications, mainly in the fields of power, industrial control, medical equipment, consumer electronics, and automotive electronics. It is commonly used in power systems, such as power supplies, switching power supply converters, frequency converters, inverters for regulating motors, UPS systems, bus output systems, computer peripheral control systems, and data processing systems in industrial automation. The SP1008-123H is also used in medical equipment such as CT, MRI and ultrasound machines. In consumer electronics, it can serve as a filter capacitor or power stabilizer in audio power amplifiers, shared audio amplifiers, hi-fi amplifiers, and other sound equipment. Additionally, it is widely used in automotive electronics for controlling motors in automotive air-conditioning systems, wiper systems, and power steering systems.

Working Principle

The SP1008-123H is a fixed inductor of equivalent circuit characteristics, which means it is composed of a coil, two capacitors and a resistor arranged in a series circuit. The coil encircling part of the circuit is referred to as the inductor and the capacitor is made up of two components, one of which is connected in series and the other in parallel. The resistor is connected in series between the two capacitors. As current flows through the inductor, the voltage builds up across the components of the series circuit. This voltage is regulated by the capacitors and the resistor, and is then output in the form of a voltage that is based on the components of the series circuit.

The SP1008-123H is designed to be very suitable for delay line applications. As current passes through the inductor, the voltage across the two capacitors and resistor increases in a linear manner, producing a relatively low level voltage output. This voltage output is then amplified to provide the desired delay time.

Furthermore, the SP1008-123H is used in filter applications, utilizing the series circuit of the inductor, capacitor and resistor to create a low pass filter. This filter has the function of suppressing the high frequency components of the input signal and isolating the low frequency components, effectively producing a clean signal output without unwanted noise. It also has the function of eliminating current noise caused by ground loop common mode, thus ensuring the stability of the input signal.

Conclusion

The SP1008-123H is a fixed inductor with a variety of applications in power systems, medical equipment, consumer electronics, and automotive electronics. It is composed of a coil, two capacitors and a resistor arranged in a series circuit, and is used in delayed line and filter applications. The SP1008-123H is a reliable and cost-effective fixed inductor with a wide range of application possibilities.
