The TM-2025A Electronic part with Multi-Directional Switches SMD RoHS is a series of two-stage common-mode filters manufactured by XKB. It is specifically designed for high-speed serial data bus applications, such as Ethernet, USB, audio and video over Ethernet, and telecoms, in which EMI/RFI problems can occur. It features two stages of common-mode attenuation that eliminates EMI/RFI noise coupled from external sources to the data bus. The two-stage filtering offers higher performance than one-stage common-mode filters, which provides superior EMC performance over a wide frequency range. It’s designed with RoHS compliant, surface-mountable multidirectional switch that enables users to select among four available configurations, eliminating the need for a separate switch that needs to be mounted. It features an operating temperature range of -40°C to +125°C, making it ideal for use in harsh environments. The device is compatible with a wide range of buses, making it a very versatile and handy solution for data bus applications.
