USB connectors protect and filter

26 February 2003 Circuit & System Protection

Spectrum Control has introduced an ESD-protected and an EMI-filtered USB connector series. This introduction into ESD USB connectors includes the Type A family with right angle PCB mounting and are designed specifically for USB 2.0 applications.

The Series USB-E ESD connectors have integrated transient voltage suppressors from Littelfuse. The Series USB-F EMI connectors have integrated chip capacitor filters or ESD suppressors. Both series are drop-in replacements for standard unfiltered connectors. Custom values and capacitive filtered combinations are also available.

Main applications are in EMI/RFI sensitive electronics, test and measurement equipment, computer equipment and peripherals.

Key electrical specifications: operating temp. -25 to +80°C; working voltage 10 V d.c.; 5 A; effective filtering from 5 MHz to 5 GHz; capacitance 0,055 pF to 1000 pF (USB-E ESD) and 22 pF to 1000 pF (USB-F EMI); insulation resistance 1 GΩ; contact resistance 15 mΩ max.
