Fixed Inductors

Inductors are important components used in electrical and electronic circuits since their discovery. Fixed inductors are components with a single inductance value that does not change, typically found in low-frequency analog circuits where stability is critical. They are popular because they help reduce costs, temperatures, and – in some cases – sizes. The most common types of fixed inductors are non-magnetic, ferromagnetic, and film type.The IMS05EB390K is a fixed inductor designed and developed by the TDK-EPC Corporation. It is classified as a non-magnetic type inductor, and comes in a ceramic shielded molded package – measuring only 4.5mm x 4.5mm, making it ideal for miniaturized applications. This product has a wide range of usable frequencies ranging from 20kHz to 300kHz, and a rated operating temperature range between -40°C and 85°C.The IMS05EB390K is a multi-turn inductor, meaning it has an additive core composed of multiple turns of wire, creating an inductance larger than a single winding would otherwise produce. It has a special winding arrangement utilizing tightly wound turns of inner coil to achieve a high quality factor, in combination with a effective use of gap shielding, helping to minimize mutual inductance.The application field for the IMS05EB390K involves any miniaturized system that requires a low profile, high power, high quality factor inductor operating between 20kHz and 300kHz. Specifically, this product is suitable for DC-DC converters, radio communication transceivers, radar systems, ultrasonic cleaning systems, and power supplies.The core of the IMS05EB390K is its working principle. By utilizing its multiple winding layout, the the inductor is able to effectively store energy in the form of a magnetic field generated by a direct current. This is due to the opposing magnetic fields around each turn – generated by the same amount of current – resulting in an interaction between these fields and the consequent reinforcement of the induction. This is important for DC-DC converters because it provides an ideal load for high frequency AC waveforms and helps maintain stability while minimizing electromagnetic interference.In conclusion, the IMS05EB390K is an economical and efficient fixed inductor, ideally suited for applications in the radio frequency range, such as DC-DC converters, communication transceivers, and power supplies. Its ability to provide a highly stable storage of potential energy makes this product an ideal solution for miniaturized electronics.
