Fixed Inductors

Fixed inductors, otherwise known as chokes, are devices that store energy in a magnetic field and help to resist a change in the flow of current, usually used to filter noise in electronic circuits.

SP1812R-332K

SP1812R-332K is a type of fixed inductors featured with a helical construction and low current capability. It is designed with high-performance properties such as high electromagnetic performance, wide operating temperature range, long-term reliability, high temperature and voltage. It is widely applied in power supply, communication, consumer electronics, computer and automotive industry.

Application Field and Working Principle

The SP1812R-332K is used as an inductor in DC-DC converters or in filtering circuits for the suppression of high frequency noise. Its role in circuitry is to stabilize or block the flow of current, either through the inductor itself or via an external component. The magnetic field created by the inductor induces an electromotive force in which results in a voltage drop across the device.

In DC-DC converters, inductors play a vital role in buck-boost converter, flyback converter, and forward converter topology. Its main objectives are to energy storage, provide a steady flow of current, boost or decrease voltage and filter high frequency noises. Ultimately, all these features allow to help obtain desired output voltage levels.

The SP1812R-332K has a good balance between the inductance and current capabilities compared with other inductors. This makes it suitable for a wide range of applications, such as in DC-DC converters, as a line noise filter or as a load balancer.

This product is designed with the highest quality materials and is tested in its relevant application and environment to ensure its proper function. It offers a wide range of operating temperature from -40°C to 125°C, high temperature resistance, and long term reliability.

Due to its long-term reliability and high performance in its relevant application, the SP1812R-332K is suitable for a wide range of applications in power supply, telecommunication, consumer electronics, computer and automotive industry.
