ELL-4LM270M Inductors, Coils, Chokes

Fixed inductors are used in electronics and electrical circuits to keep the current in a device or circuit constant. The ELL-4LM270M is an inductor designed to meet stringent requirements from top-tier automotive suppliers. This inductor is designed to be low profile, with a nonmagnetic frame and a large diameter coil. This allows it to provide excellent isolation at high frequencies, as well as a wide range of power efficiencies. Additionally, the ELL-4LM270M has an operating temperature range from -55 C to +125 C.

The ELL-4LM270M can be used in a variety of applications, such as in amplifiers for audio and video, as well as in high-speed circuits. It can also be used in switch mode power supplies, chassis grounding, power line conditioning, power line filters, and as a filtering component in DC-DC converters. The inductor also has a low resistance of 1.35 ohms in free air, enabling it to be used in high current applications such as motor control and other high current DC-DC and AC-DC power circuits.

In terms of its actual working principle, the ELL-4LM270M inductor works when current passes through it which creates a magnetic field. This magnetic field then induces an opposing current in the opposite direction, creating a low pass filter that impedes the current from switching devices and helps eliminate high-frequency ripple current. This effectively prevents noise and other electromagnetic interferences from entering the system and keeps the power voltage constant. Because it helps in reducing high-frequency noise, the ELL-4LM270M is seen as a great asset for controlling high-frequency noise on circuit boards.

The ELL-4LM270M is also known for its high temperature performance, as it is designed to work safely for extended periods in temperatures up to 125°C. This makes the ELL-4LM270M ideal for automotive applications such as air bag solenoids, engine start-stop applications, and electronic throttles, where temperature control is important. Additionally, its low current loss makes it suitable for high frequency applications such as DC to DC converters, server power supplies, and wireless charging.

Overall, the ELL-4LM270M is a great choice for a variety of applications in automotive and other fields due to its high temperature performance, low current loss, and wide range of power efficiencies. Additionally, its working principle helps keep the power voltage constant while also eliminating high-frequency interferences, which makes it a highly reliable inductor.
