Protect expensive USB devices from noise, surges
and spikes.

These small, affordable in-line isolators
eliminate ground loops, too.

SP386A

SP3 87A

Product Overview

• SP387A is certified up to 4kV isolation, 8kV contact, 15kV
air ESD.

• SP386A provides 2-kV triple isolation for safeguarding data
and equipment in heavy industrial settings.

• Both of these high retention USB connectors feature an
ultra-compact in-line design.

• Powered from the USB bus; no drivers are required.

• Designed to withstand both shock and vibration.

• Data rates up to 12 Mbps.

Protect expensive PCs and equipment from damaging electrical
storms, power surges, and other high EMI/RFI disturbances.
This heavy-duty line of isolators packs a powerful punch
against electrical noises, surges and spikes, and it eliminates
ground loops, which are disruptive in measurement
applications.

Both isolators are USB bus powered and provide up to
100 mA of current to attached downstream devices. They
comply with the USB 1.1 standard and transfer data at
12 Mbps.

Standard USB cables of up to 5 meters may be used on either
side of the products.
