Tubular FT Capacitors API Technologies’ Spectrum Control brand manufactures a wide variety of tubular feed-through (FT) ceramic capacitors, which are small in size, lightweight, nonpolar and offer high dielectric strength. Operating temperatures of –55°C to +125°C are achieved with no voltage de-rating. All capacitors are fired to produce true monolithic structures, which are impervious to moisture and contamination. Outer terminations feature a nickel barrier and a final metal layer, typically silver. Feed-through tubular capacitors are ideally suited for by-pass and filtering applications. Due to the cylindrical design, the capacitors will have uniform insertion loss over a broad frequency range. This structure yields a low inductance when compared to conventional wound capacitors. Solid FT capacitors have no internal electrodes and find their primary usage in low cost applications. Multilayered FT capacitors have a higher capacitance to volume ratio and are ideally suited for greater filtering at lower frequencies. Multilayered FT capacitors are also designed for applications where source impedances are high and sharp attenuation rise is critical. ■ ■ ■ ■ ■ Solid C-termination Ground (common) Insulation C-termination Multi Layered Ground (common) Features ■ Feed-Through Construction Low cost solution for general purpose filtering Ideal for multi-pin connector applications High ratio of capacitance to volume Low inductance, non-polar Impervious to moisture and contamination -55°C to +125°C operation Insulation C-end termination Insertion Loss Feed-Through Circuit C Insertion Loss (db) Per MIL-STD-220 Curve 1 2 3 70 4 5 6 60 7 8 F .1 uF 1. 4u F 50 9 10 10 00 27 20 pF 00 .0 27 .2 7 30 50 .0 pF 00p 1uF F uF .0 uF 56u F .5 6u 40 10 0 0 01 01 1 10 100 1000 Frequency (MHz) API TECHNOLOGIES • 8061 Avonia Rd. • Fairview, PA 16415 • Ph: 814-474-1571 • Fax: 814-474-3110 • eis.apitech.com API TECHNOLOGIES’ SPECTRUM CONTROL GmbH • Hansastrasse 6 • 91126 Schwabach, Germany • Phone: (49)-9122-795-0 • Fax: (49)-9122-795-58 CC8 ID Tubular FT Specifications Length OD Banding Dimensions Center Dimension, min.
