Filtered D sub connectors

Paul Boughton

Manutech Europe manufactures a complete range of filtered D sub connectors, including standard density (9, 15, 25, 37 & 50 way), high density (15, 26, 44, 62 & 78-way), power (2W2, 3W3, 5W5, 8W8) and mixed/combo layout versions (7W2, 9W4, 17W5, etc).

All connectors are available in plug or socket configurations and with solder cup, straight PCB or 90° (European and US footprint) terminations. Signal contacts are rated up to 5A and power contacts are available rated from 10A to 40A.

The connectors are made with turned/machined contacts with gold plating to provide a minimum 500 mating/insertions. All designs have sealed resin encapsulation of the filter elements for improved mechanical and environmental protection.

Filtering is achieved using feedthrough technology  which minimises stray capacitance and enhances high frequency attenuation.  Filter configuration types include, C, LC, L & Pi.  Various capacitance values are available, for example 47pF, 120pF, 220pF, 330pF, 470pF, 680pF, 820pF, 1nF, 2nF, 4.7nF. Higher values are available on request.

Multilayer planar technology filter solutions are also available for aerospace and military applications where high reliability solutions are required. C & Pi circuit configurations are available with values up to 100nF.
