The MAF series of noise suppression filters now includes the new MAF2520ASS600C type that is designed especially for LED lighting systems. The new multilayer filter has compact dimensions of just 2.5×2.0×0.85 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 to +125°C, the component is also suitable for use in high temperature environments. In addition, the new MAF2520ASS600C filter satisfies CISPR 15 standards for LED lighting. Mass production began in January 2018.
To offer additional enhanced value, manufacturers are developing intelligent solutions with networked illumination control systems. The new miniaturized MAF2520ASS600C noise suppression filter from TDK is designed to protect the controllers from the noise generated by the ac-to-dc LED power supplies.
Main applications: Networked LED lighting systems in homes and buildings. Main features and benefits: Suppression of spurious noise between 20 MHz and 100 MHz
Wide operating temperature range of -40 to +125 °C for use in high temperature environments. Satisfies CISPR 15 standards for LED lighting.
