Fixed inductors, also known as chokes, are devices that store electrical energy in a magnetic field and resist a change in current. They are commonly used in electrical circuits to filter electronic noise, provide a steady signal and keep the current within safe levels. The SP1812R-822H is one such inductor that is used in a variety of applications.
The SP1812R-822H is a radial power choke coil with two windings and a ferrite core. It is rated at 120mA and has inductance up to 8.2uH. This inductor is designed for use in switching power supplies applications such as PC, LCD, printer and other electronic devices.
The SP1812R-822H inductor has a number of features that make it suitable for its purpose. It has a low DC resistance of 0.05Ohms, a high alternating current (AC) resistance of 10kOhms at 50MHz and low core loss. It also has a high working temperature of up to 125°C. This makes the SP1812R-822H suitable for use in high temperature environments.
The SP1812R-822H works by storing electrical energy in a magnetic field formed between the two windings. When a current is applied to the inductor, a magnetic field is generated and the inductor acts as an opposing force to the change in current. This creates a voltage drop which reduces the current drawn from the power source, thus allowing the DC voltage to remain steady.
The SP1812R-822H is often used in AC/DC converters, DC/DC converters, switch controllers, motor controls and home appliances. It is also used in DC/AC inverters, uninterruptible power supplies (UPS), EMI filters, voltage regulators and various other switch mode power supplies (SMPS) applications. For example, the SP1812R-822H is used in the circuit of a laptop charger to filter electronic noise and protect the laptop from any sudden spikes in voltage.
Overall, the SP1812R-822H inductor is an effective and reliable device that is widely used in a variety of applications. Its high temperature capability, low DC resistance and high AC resistance makes it suitable for use in thermally demanding applications. It performs efficiently in AC/DC converters, DC/DC converters, switch controllers and other power supplies. This makes it a reliable and efficient inductor for various electronic devices.
