TDK Launches a Series of Inductors Suitable for Industrial Ethernet (SPE) Applications

TDK Corporation has developed a series of inductors for industrial Single Pair Ethernet (SPE) 10 BASE-T1L applications based on the IEEE 802.3cg standard. Suppression of asymmetric interference is critical for interference-free data communication, and the new RCM70CGI-471 common-mode choke with an inductance value of 470 µH, a rated voltage of 80 V, and a rated current of 700 mA is ideal for such applications.

For some designs that require electrically isolated PHY chips and connectors, ICI70CGI series isolation inductors with a transformation ratio of 1:1 can be used. The family of components is available in 1.0 mH and 2.2 mH inductance values and has an isolation voltage of 2250V DC.

With Power over Data Line (PoDL) technology, the system requires only one pair of wires to connect the actuator and sensor and transmit both data and power. However, the system requires special differential mode chokes to suppress interference. The new PID* series of components are available in different size versions to cover all 6 power classes (10 to 15) according to the IEEE 802.3cg standard, with saturation currents ranging from 360 mA to 2100 mA. The same new PIS150H-471M component adopts a single choke structure design, which can effectively suppress noise and smooth current, and the maximum saturation current is 2300 mA.
