Expanding its high-reliability TWA series, AVX has introduced high voltage COTS Plus axial-leaded, wet electrolytic tantalum capacitors. Featuring a high capacitance cathode system that enables high CV levels in DSCC-compatible case sizes and new ratings as high as 4700µF/25V, 3000µF/50V, 2200µF/60V, 1000µF/75V and 750µF/100V, the capacitors are suited for use in high-reliability defence, avionics, radar and power supply applications.
The TWA series COTS Plus wet electrolytic tantalum capacitors are available with seven voltage ratings (25, 30, 50, 60, 75, 100 and 125V), 26 capacitance values spanning 10µF to 5,600µF, four DSCC-compatible case sizes (T1–T4), two capacitance tolerances (±10 and ±20%) and two termination finishes (Sn/Pb 60/40 and lead-free compatible matte tin).
Chris Reynolds, Technical Marketing Manager, Tantalum Products, AVX, commented: “The new high CV ratings of the TWA series COTS Plus wet electrolytic tantalum capacitors make them well suited for use in a wide variety of harsh environment, high-reliability applications and we’re still actively expanding the series. With 17 new codes currently under development and five available as samples, we can continue to expand the number and type of applications that can benefit from the series’ reputable performance.”
The RoHS compliant tantalum capacitors are also available with and without an insulating sleeve and with three levels of qualification: Extended Range; COTS Plus; and Group A level testing. The capacitors are shipped in a tray pack with a standard lead time of 8-10 weeks across the series. Lead times for components with custom capacitance and voltage packages, which are both possible and welcomed, will vary.
