SMD pulse transformers for Gigabit Ethernet and PoE

SMD pulse transformers for Gigabit Ethernet and PoE

• Designed for high transmission rates of up to 10 Gbit/s
• Support Power over Ethernet applications at 1 Gbit/s
• Special core design optimized for fully-automated production processes
February 6, 2018
TDK Corporation has expanded the ALT4532 series of pulse transformers with new types for Gigabit Ethernet and Power over Ethernet (PoE) applications. The new ALT4532P type is designed for emerging 2.5GBASE-T (2.5 Gbit/s) and 5GBASE-T (5 Gbit/s) LAN applications as well as 1000BASE-T (1 Gbit/s) applications with 600-mA PoE. The new ALT4532H type is compatible with the 10GBASE-T standard (10 Gbit/s). The components feature a compact SMD package with dimensions of 4.5 mm x 3.2 mm x 2.9 mm. Mass production of the new pulse transformers was launched in February 2018.
In recent years, Ethernet standards have been established for higher transmission rates up to 10 Gbit/s. With the new ALT4532 components TDK is responding to the rising demand for compact pulse transformers for these high-speed LAN interfaces, in particular, for the growing number of IoT devices. Thanks to their compact IEC 4532 packages, these SMD components are suitable for circuit board layouts with many pulse transformers.
Unlike conventional products with toroidal shaped cores, the new TDK transformers feature a special core design that is optimized for fully-automated production and winding processes, resulting in extremely stable quality. The discrete ALT4532 types offer designers greater flexibility for circuit board layouts than conventional LAN modules that combine pulse transformer and common-mode filters in a single package, for example, enabling mounting on both sides of the PCB.

Compact noise suppression filters for LED lighting

• Suppression of spurious noise between 20 MHz and 100 MHz
• Noise suppression performance equivalent to that of larger wire-wound components
• Satisfies CISPR 15 standards for LED lighting
January 23, 2018
TDK Corporation has expanded the MAF series of noise suppression filters with the newMAF2520ASS600C type that is designed especially for LED lighting systems. The newmultilayer filter has compact dimensions of just 2.5 mm x 2.0 mm x 0.85 mm and features asuppression of spurious noise between 20 MHz and 100 MHz that is equivalent with that oflarger wire-wound components. The new component has a rated current of 500 mA and alow 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.
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 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. Moving forward, TDK will continue to develop filter products that offer high-performance noise suppression in even smaller dimensions.
