Pasif USB 2.0™ EMI Filter
The Pasif USB 2.0™ electromagnetic interference (EMI) Filter is the most effective passive, unpowered EMI filter for Universal Serial Bus available on the market. The filter is designed to pass signals at Low Speed (LS - 1.5Mb/s), Fast Speed (FS - 12Mb/s), and High Speed (HS - 480Mb/s) while simultaneously blocking all unwanted signals at better than 80dB starting from 700MHz and better than 90dB starting at 750MHz up to 40GHz. Military-grade passive filtering technology ensures that USB signals traverse the filter in complete and absolute isolation. The result is a pristine digital output far surpassing the filtering capabilities of other passive USB 2.0 filters.
Each Pasif USB 2.0™ EMI Filter is mounted in a rugged protective housing machined from solid aluminum stock. The housing provides both physical protection and enhances EMI filtering effectiveness. The unique structure of the housing disrupts undesirable emissions while directing interference away.
Features:
- Military-grade passive filtering techniques for clean and sharp signals
- Highest quality electrical components ensure long service life
- Rugged protective housing ensures reliability in any environment
- Passive electrical design allows flexibility in location and operation
