Tantalum Chip Capacitors target aerospace applications.

Press Release Summary:




Featuring conductive polymer electrodes, TCH Series offers capacitance values from 1.5–680 µF and voltage range spanning 10–100 V. Space-grade SMD devices are hermetically sealed in ceramic cases filled with inert gases to eliminate material and performance degradation from exposure to high temperature, humidity, and ambient atmosphere. Rated for use in temperatures from -55 to +125°C, capacitors are available with J-lead or under-tab terminations.

AVX Announces the Availability of New TCH Series Hermetically Sealed Tantalum Polymer Chip Capacitors for Aerospace & Hi-REL Applications



Featuring conductive polymer electrodes, TCH Series capacitors exhibit low ESR, high capacitance, high voltage, & excellent performance stability



GREENVILLE, S.C. -- AVX Corporation, a leading manufacturer of passive components and interconnect solutions, has announced the availability of its new TCH Series hermetically sealed tantalum polymer chip capacitors for aerospace and other high-reliability applications.  Featuring conductive polymer electrodes, TCH Series capacitors exhibit very low ESR and low derating capabilities in addition to high ripple current, high capacitance (1.5-680µF), and the highest voltages (10-100V) of any space-grade SMD tantalum polymer capacitor currently available on the market.



"The TCH Series was initially developed for a mission-critical European Space Agency application that required both extremely high capacitance and very low ESR, which tantalum polymer technology is particularly well-suited for," said Allen Mayar, product marketing manager at AVX.  “Having overcome the material's sensitivity to the combination of high temperature and high humidity by hermetically sealing the capacitor in a ceramic SMD case filled with inert gas, which eliminates humidity and oxidative degeneration, AVX now offers the highest voltage space-grade SMD tantalum polymer capacitors on the market." 



Hermetically sealed in ceramic cases filled with inert gasses to eliminate material and performance degradation resulting from exposure to high temperature, high humidity, and ambient atmosphere, TCH Series capacitors exhibit excellent performance stability in aerospace and other high-reliability applications, as well as enable a significant payload reduction for power supplies. 



Housed in large CTC-21D cases, AVX's new TCH Series hermetically sealed tantalum polymer chip capacitors provide high capacitance values, spanning 1.5µF to 680µF, and high rated voltages, spanning 10-100V.  Rated for use in temperatures ranging from -55ºC to +125ºC, TCH Series capacitors weigh a mere 2.4g each and are available with either J-lead or standard under-tab terminations.  Dimensions for TCH Series capacitors with J-leads are: 11.8mm x 12.5mm x 5.8mm.  Dimensions for TCH Series capacitors with under-tab terminations are: 11mm x 12.5mm x 5.45mm.
