USB 2.0 jack with integrated EMC filter

Specifically intended for deployment of the USB interface in industrial applications, this socket avoids the need to design a separate filter

Wurth Electronics has a USB 2.0, type A jack, the WE-EPLE, which the company believes is the only USB jack with an integrated EMC filter and ESD protection. It is pad-compatible with most conventional USB jacks, and the dimensions also stay the same. Existing designs are transformed into EMC-compatible designs in little time. The integrated EMC filter eliminates broadband interference on voltage and signal lines, and at the same time, is almost invisible for the signal lines.

This means:

- VCC filter impedance above 100Ω in the 20 MHz range to in excess of 1 GHz

- Common-mode suppression at 240 MHz in excess of 250Ω

ESD suppression at levels of 10V at level 4 ESD pulses with 15 kV.

The WE-EPLE, USB 2.0, type A jack, is compatible with the USB 2.0 standard.
