Fixed Inductors

Fixed inductors essentially consist of two parts, a core surrounded by a coil or winding. They are widely used in almost all types of electronic applications. Their primary purpose is to provide a fixed, single-frequency resistance to the alternating current that passes through them. In addition to this, they also provide a certain degree of voltage and current regulation which is vital in many circuits.

30800AC application field and working principle

The 30800AC series fixed inductors from TDK Corporation is a family of products specifically designed for audio frequency filters and high frequency power supplies. These inductors feature a square flat molded package construction which is more conducive to PCB assembly than traditional cylindrical packages. The central iron core is made from an amorphous alloy for maximum conductivity without eddy current loss, and the winding is composed of several fine copper wires for maximum current density.

The basic operating principle of an inductor is based on Faraday\'s Law. According to this law, when a current flows through a conductor, a magnetic field is produced around the conductor. When the direction of the current is reversed, the direction of the force is reversed as well. This force produces an opposing force on the conductive material causing it to resist the flow of current. The induced voltage in an inductor is linearly proportional to the rate of change of current.

The 30800AC series offers an inductance range of from 10 nH to 100 uH and provides an isolation rating of 4000VAC with a working frequency range of 0.4MHz to 2MHz. They are well-suited for use in audio bands and are ideal for filters, power supplies, and other circuits in a range of applications such as test and measurement equipment, communications, medical, consumer electronics, and gaming.

The 30800AC series offers an operating temperature range from -40°C to +125°C and can stand up to stringent environmental conditions. The winding is also designed with a self-healing mechanism, which helps protect it from shorts due to broken strands. The inductors are lead-free and RoHS compliant for use in industrial and consumer applications.

The 30800AC series is available in a variety of package sizes, from tiny 0603s to large 1020s. The inductors are highly reliable and made to last for many years of continuous operation. With TDK\'s commitment to quality and performance, these products are sure to provide reliable, consistent, and reliable power to all electronic devices.
