Noise suppression filter for LED lighting

31 January 2018 Circuit & System Protection

TDK has expanded the MAF series of noise suppression filters with the new MAF2520ASS600C type that is designed especially for LED lighting systems. The new multilayer filter has compact dimensions of just 2,5 x 2,0 x 0,85 mm and features a suppression of spurious noise between 20 MHz and 100 MHz that is equivalent with that of larger wire-wound components.

The new component has a rated current of 500 mA and a low DC resistance of just 0,28 Ω (typical). Its impedance at 30 MHz is 3,4 kΩ. Thanks to its wide operating temperature range of -40°C to +125°C, the component is also suitable for use in high-temperature environments. In addition, the filter satisfies CISPR 15 standards 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. The miniaturised MAF2520ASS600C noise suppression filter is designed to protect the controllers from the noise generated by the AC-DC LED power supplies.
