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.

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. Compared to feed-through tubular capacitors, Pi tubular capacitors have a much narrower transition between the pass and stop bands. Pi capacitors are effective in stopping high frequency interference without affecting necessary frequencies immediately below the stop band. Similar to feed-through tubular capacitors, Pi tubular capacitors can be designed with a solid or multilayered configuration. Solid Pi tubular capacitors are more cost effective, but limited in capacitance values. Multilayered Pi tubular capacitors can cover a wider range of capacitance, while still maintaining the mechanical strength of a solid Pi tubular capacitor in a similar case size.

Component selection is typically determined by dielectric performance, electrical environment and temperature stability. In determining the proper component for a specific application, the following information should be considered. Dielectric Type There are three basic dielectric classes (characteristics) available: DIELECTRIC PROPERTIES Dielectric Type Stability Class BP Ultra Stable (NPO and COG) Class I BQ, BR, BX and X7R Z5U and Y5V Stable Class II General Purpose Class II NPO (COG) Dielectric Characteristics Capacitor Selection Description Effects on electrical properties are minimal with temperature, frequency or time. Used in applications which require stable performance. Effects on electrical properties predictably change with temperature, voltage, frequency and time. Selected for applications where blocking, coupling, by-passing and frequency discriminating elements are used. Offers higher capacitance than Class I (COG). Exhibits a greater variation of properties with temperature. Dielectric constant is higher than Class I and Class II dielectrics. Extremely high capacitance per unit volume and used in general performance applications. Operating Temperature Range ...........................

Typically smaller units are less expensive and provide for greater space savings. Because mass affects the thermal response of the chips, size should be considered when selecting the attachment method to the circuit. TERMINATION MATERIAL Material Type Recommended Usage Silver Palladium Silver Nonmagnetic application requirements. Recommended for conductive epoxy and leaded attachment methods. For soldering applications, use solder reflow below 230°C. Most ductile of the available termination methods. Used in applications which will be leaded, to minimize thermal stresses.

Like all ceramic components, SMPS capacitors are subject to thermal stresses. For this reason, preheating of the capacitor assemblies is recommended. Preheat components using hot plate to 120 to 150°C, or within 50 to 60°C of the soldering temperature being applied. Avoid over-exposure to high temperatures during assembly and allow for gradual, post-assembly cooling. ■ For hand iron soldering, recommended soldering iron tip temperature is 330 to 350°C. Contact the pad adjacent to the pre-tinned lead should be made from below the PCB (opposite of the component side), and the dwell time on the solder joint should be less than five seconds. An aluminum heat sink plate may be placed adjacent to the SMPS lead frame to protect the ceramic body during assembly. Avoid direct contact between soldering iron and ceramic during assembly process. Soldering time is dependant upon heat sinking provided by the chassis and board material, so a longer preheat cycle may be required. ■ Standard solders (Sn60, Sn63, Sn60/38/2) may be used. Please consult the factory for use with RoHS compliant solders. ■ Use a controlled temperature profile ramp not exceeding 4°C per second as measured by an attached low mass thermocouple. ■ Soldering time and temperatures can vary with component size, board material and layout. Please consult the factory for assistance.

API recommends the use of a silver (Ag) bearing solder when terminating directly to ceramic capacitors to reduce the potential for leeching. Gradual heating and cooling of the components are essential to prevent thermal stresses to the ceramic.
