LOW LEAKAGE MEDICAL FILTERS


RFI will design, develop and obtain agency (UL, CUL, VDE, etc.) approval for the medical filter applications requiring low leakage current to ground. This family of filters provides exceptional common-mode and differential mode insertion loss under actual operating conditions. Custom designs incorporate a variety of non-magnetic metal enclosures for maximum shielding effectiveness.

1 mA - 3 mA

Voltage
115 - 660 Volts

Current
.01 - 300 Amps

Frequency
DC, 50, 60 & 400 Hz

FILTER CONNECTOR ASSEMBLIES - RF16800 SERIES

RFI INTRODUCES NEW “CUSTOM FILTERED CONNECTORS”. THIS DESIGN INTEGRATES MIL-STD CONNECTORS WITH “QPL” SUBMINIATURE FILTERS. THE INTEGRATED FILTER CONNECTOR OFFERS SIGNIFICANT WEIGHT AND  COST SAVINGS AND ALLOWS FOR SIMPLIFIED CUSTOMIZATION, SERVICEABILITY AND EASE OF INSTALLATION .

RFI CORPORATION CAN DESIGN A CUSTOM “FILTERED CONNECTOR” FOR SPECIAL APPLICATIONS, WHICH INCLUDES POWER LINE FILTERS, SIGNAL FILTERS, DATA FILTERS AND COMMUNICATION FILTERS ASSEMBLED INTO THE BASE OF MIL-STD CONNECTORS.

IN MOST APPLICATIONS, THE FILTER CONNECTOR ASSEMBLY WILL FIT THE SAME FOOTPRINT AS THE STANDARD CONNECTOR, WITH A SLIGHT INCREASE OF THE DEPTH.

PLEASE CONTACT RFI ENGINEERING FOR SPECIFIC APPLICATIONS AND
PRODUCT DESIGN SOLUTIONS

Subminiature QPL filter capabilities
