Title: Noise suppressor
Inventor: MEYER DENNIS R
IPC: H03H1/00
Filed: 1996-03-01
Abstract: A distributed low-pass filter typically attenuating a signal, 7 db. at 10 MHz., 18 db. at 30 MHz., and continuing at 50 db/decade, out resonant inflections, uses a small, low cost, rectangular tabular bead of outside dimension 3 mm. x 6 mm x 2 mm, made from a body material having evenly distributed magnetic, dielectric, and resistive properties. A through-conductor completes the distributed filter which acts like a high loss cable transmission line. The tube's inner and outer surfaces are separately coated with an electrode material. The through-conductor electrically connects to the inner electrode, with its ends providing first and second filter terminals, and the outer electrode providing a common, terminal. An a.c. signal impressed between the first and common terminals produces an attenuated signal between the second and common terminals in accordance with the above characteristics. Also, a 6 mm x 6 mm. x 1 mm block of the body material may typically form a 500.mu.F power-line, noise suppressor. The above devices may include bidirectional, zener-like, voltage limiter capability; absorbing noise and electrostatic discharges, like varistors. A preferred body material is a sintered mix of oxides of manganese and iron, modified by oxides of zinc, nickel, or other metals. This soft ferrite, ceramic adapts to make surface mounted devices. Small, low cost RF noise suppressors, line terminators, or impedance matching filters for use in high frequency (baud rate) cable connectors may be molded individually, or integrated as multiple devices.
