Fixed Inductors

Fixed inductors, also known as inductor coils, are passive electronic components mainly used in electronic circuits for signal filtering, resonance, signal generation, power conversion, etc. Fixed inductors have two crucial characteristics: inductance and DC resistance. The former is related to the current AC induced by a changing magnetic field, while the latter is related to the power consumption related to the wire. Traditionally, fixed inductors have been used in analog circuits, but recently they are being used in digital circuits as well.

IMS05RU270K Application Field and Working Principle

The IMS05RU270K is a fixed inductor with a mono-wound, heavy-duty construction, and a rated inductance of 270 nH. It is mainly used in low-frequency to high-frequency switching power supplies, such as notebook PCs, desktop computers, and laptop computers. This inductor has an operating voltage range of up to 30 VDC, making it suitable for use in high-voltage power supplies.

The IMS05RU270K operates based on Faraday\'s Law of Induction. The cross section of the inductor is designed with the wire wrapped around the plastic core to form multiple turns, creating a magnetic field with a changing intensity when a current is applied. This changing magnetic field then induces a voltage in the opposite direction, creating an inductive effect. This effect is used to store energy in the inductor and release it when needed.

The IMS05RU270K features a metal shield to reduce EMI noise, along with a Teflon coating for durability and protection. The outer coil is made of 15-Ni-200 magnet wire with a high temperature polyimide insulation. This provides a reliable insulation layer between the primary and secondary windings, ensuring a safe and reliable operation. Additionally, the IMS05RU270K uses Shizuki Shield Construction to further reduce noise, making it suitable for use in high-frequency applications.

The IMS05RU270K is able to deliver a wide range of outputs, making it well-suited for use in a variety of applications. It has a maximum rated current of 10 A, a peak current of up to 20 A, and a DCR of 0.285 Ohm, allowing it to provide good signal integrity in digital systems. Additionally, the inductor is capable of withstanding temperatures ranging from -55°C to +120°C, making it suitable for use in harsh environments.

The IMS05RU270K is a reliable and cost-effective inductor, making it an ideal choice for designing low-noise and high-frequency power supplies. Its shielded construction and wide operating temperature range make it suitable for many applications, including computer power supplies, automotive power supplies, and audio systems.

In conclusion, the IMS05RU270K is an excellent fixed inductor, providing a reliable and cost-effective solution for applications requiring low-noise and high-frequency power supplies. It is well-suited for a variety of applications and its shielded construction ensures reliable operation.
