https://uk.farnell.com/ New LCT said to “redefine power supply noise suppression” M
urata has launched the L Cancel Transformer (LCT), which is designed to neutralize the equivalent series
inductance (ESL) of a capacitor, optimizing its noise-reducing capabilities. Utilizing Murata’s exclusive ceramic multilayer technology, this solution is said to allow engineers to reduce system noise while decreasing costs and component count. As the demand for miniaturized and highly functional electronics increases, the issue of electromagnetic noise is becoming increasingly prominent for many industries. As a noise countermeasure, capacitors are often utilized between the power supply line and ground. The noise removal effectiveness
of the capacitor is optimal when a capacitor’s impedance is lowest. However, capacitor impedance can rise due to its ESL, particularly at frequencies beyond the self-resonant frequency, undermining the efficacy of the noise cancellation. To minimize this impact, it is common practice to connect numerous capacitors in parallel in order to collectively reduce impedance, at the expense of Bill of Material (BoM) component count and costs. Murata’s LCT is capable of resolving the longstanding challenge of managing power supply noise and capacitor component count. Murata’s LCT component is specifically engineered to minimize noise within the frequency range of a few MHz to 1GHz. It achieves this by utilizing negative mutual
inductance to reduce a noise- reducing capacitor’s ESL and therefore increase the effectiveness of its operation, drastically reducing the number of required capacitors.
By using non-magnetic
ceramic multilayer technology in its construction, the LCT ensures stable negative inductance and low DC resistance (maximum 55mΩ) even in the presence of current variations and is suitable for a wide range of applications, including consumer, industrial and healthcare products.
Each LCT is suitable for temperatures up to temperatures 125o
C and since there is no
DC superposition characteristic, it can be used with stable negative inductance up to 3A. The surface mount device (SMD) measures just 2.0 x 1.25 x 0.95 mm and is available in tape and reel packing.
