High-voltage tantalum capacitors

24 July 2013 Passive Components

AVX has surpassed previous voltage rating milestones with the introduction of the new TCJ 100 V and 125 V tantalum polymer capacitors. As the highest-voltage tantalum capacitors currently on the market, the new surface-mount chip capacitors provide excellent capacitance and ultra-low ESR in a compact case size.

By maintaining 20% recommended voltage derating, TCJ series capacitors significantly extend the usable voltage range and can be used for a wide array of high-voltage applications, including telecommunications equipment, base stations, switching hubs, router and line filters, DC-DC converters in LED TVs and notebook computer power supplies, and a host of industrial applications.

The new parts exhibit a benign failure mode, which eliminates the ignition failures that can occur in standard MnO₂ tantalum technology, increases robustness and mitigates any tendency to overload or burn. Subjected to strict ageing and screening processes to ensure that all parts demonstrate the highest reliability, TCJ series capacitors maintain high reliability exceeding 1% per 1000 hours at 85°C and full-rated voltage.

Rated for use from -55°C to +105°C, the capacitors come in the 2924 case size for the 100 V and 2917 for the 125 V, and are compatible with high-speed pick and place manufacturing processes.
