Murata Unveils Groundbreaking LCT Component to Reduce Power Supply Noise

Murata Manufacturing Co., Ltd., a leading electronic component manufacturer, has launched its innovative L Cancel Transformer (LCT) component, designed to revolutionize power supply noise reduction. The LCT utilizes negative mutual inductance and non-magnetic ceramic multilayer technology to neutralize the equivalent series inductance (ESL) of capacitors, optimizing their noise-reducing capabilities.

Why this matters: The development of this innovative component has significant implications for the electronics industry, enabling the creation of more efficient and compact devices that consume less power and produce less waste. As the demand for electronic devices continues to grow, this technology has the potential to make a substantial impact on reducing electronic waste and mitigating the environmental impact of the industry.

The groundbreaking LCT component minimizes power supply noise within the frequency range of a few MHz to 1GHz, making it suitable for various applications, including consumer, industrial, and healthcare products. By reducing the ESL of noise-reducing capacitors, the LCT drastically decreases the number of required capacitors, resulting in lower component count and costs.

Masamichi Ando, Vice President of the Business Incubation Center at Murata's Corporate Technology & Business Development Unit, emphasized the transformative nature of the LCT: "Murata's new LCT is a true innovation that does not merely improve what is available, but redefines what is seen as a standard noise suppression component by radically redefining the entire concept. With this revolutionary component, engineers will be able to reduce component count, system complexity and costs, helping to both further miniaturize their solutions and reduce its impact on the environment by lowering material consumption."

The LCT boasts an operating temperature range of up to 125°C and stable negative inductance up to 3A, with a maximum DC resistance of 55mΩ. This surface mount device (SMD) measures just 2.0 x 1.25 x 0.95 mm, making it ideal for space-constrained applications. The component is available in tape and reel packing for automated assembly processes.

Murata Manufacturing Co., Ltd., listed on the Tokyo Stock Exchange (TOKYO: 6981) with an ISIN code of JP3914400001, is a globally recognized leader in the design, manufacture, and supply of advanced electronic components. The company's commitment to innovation and miniaturization has positioned it at the forefront of the electronics industry.

The LCT component (Part number: LXLC21HN0N9C0L) is now entering production, with samples available for engineers and designers to evaluate its performance and suitability for their applications. This innovative solution from Murata is set to redefine power supply noise reduction circuit design, addressing a significant and persistent challenge in electronic systems.
