25 or 50 Mil Pitch, Termination Resistor/Capacitor Networks
RC NETWORKS
Small Outline, Surface Mount, EMI/RFI Reduction, Terminator
Networks
Vishay Thin Film’s termination RC network Schematic AC,
can support 18 data lines reducing overall cost. Impedance
matching of transmission lines is easily done using VTF thin
film integrated RC networks. Our product is designed with all
components integrated within a single die. It is then
packaged in JEDEC standard plastic packages. The use of
surface mount technology offers improved design capability
through reduced parasitic inductance and capacitance.
Available packages SOIC, SSOP and TSSOP.
