Noise suppression filters are designed for LED lighting

Thanks to their reduced energy consumption and long operating life, LED lighting systems have continued to become increasingly popular in a wide range of applications in homes and buildings. In order to offer additional enhanced value, manufacturers are developing intelligent solutions with networked illumination control systems.

TDK has expanded the MAF series of noise suppression filters with the addition of the MAF2520ASS600C type that is designed especially for LED lighting systems.

The multi-layer filter has compact dimensions, it measures just 2.5 x 2.0 x 0.85mm and features a suppression of spurious noise between 20 and 100MHz that is equivalent with that of larger wire-wound components, says TDK.

The MAF2520ASS600C noise suppression filter from TDK is designed to protect the controllers from the noise generated by the AC to DC LED power supplies.

The MAF2520ASS600C noise suppression filter has a rated current of 500mA and a low DC resistance of just 0.28-Ohm (typical). Impedance at 30MHz is 3.4-kOhm.

The wide operating temperature range of -40 to +125 degree C enables the component to be suitable for use in high temperature environments. In addition, the new MAF2520ASS600C filter satisfies CISPR 15 standards for LED lighting. It is currently in mass production.

TDK has announced it will continue to develop filter products in even smaller dimensions.

TDK Corporation is a leading electronics company based in Tokyo, Japan. It was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products. TDK’s portfolio includes passive components, such as ceramic, aluminium electrolytic and film capacitors, ferrites and inductors, high-frequency products, and piezo and protection components, as well as sensors and sensor systems and power supplies. The products are marketed under the brand names TDK, EPCOS, InvenSense, Micronas, Tronics and TDK-Lambda.

The company also has main product groups that include magnetic application products, energy devices, and flash memory application devices. TDK focuses on demanding markets in the areas of information and communication technology and automotive, industrial and consumer electronics.
