AVX Corp., a leading manufacturer of passive components and interconnect solutions, has surpassed previous milestones with the introduction of the new TCJ 100V and 125V tantalum polymer capacitors. As the highest rated 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 useable 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 industrial applications.
“The new, high-voltage TCJ Series tantalum polymer capacitors allow design engineers to reduce the number of components on the board, providing much greater layout flexibility than comparable aluminum electrolytic capacitors and enabling the devices they’re designed into, such as LCD monitors and LED TVs, to become even sleeker and more compact,” said Allen Mayar, product marketing manager at AVX.
TCJ series high voltage tantalum polymer SMD capacitors 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, AVX’s TCJ series capacitors maintain high reliability exceeding 1% per 1,000 hours at 85ºC and full-rated voltage.
Rated for use from -55ºC to +105ºC, AVX’s 100V and 125V TCJ Series SMD capacitors feature small case sizes (2924 for the 100V and 2917 for the 125V), low profiles, and are halogen-free in accordance with the criteria for environmentally responsible product design that were recently adopted by several other major electronics manufacturers. Compatible with high-speed pick and place manufacturing processes, the new high voltage capacitors are available on 7” and 13” pure tin reels.
