Electronica: AVX breaks 100V with tantalum polymer caps

AVX announced 100 and 125V tantalum polymer capacitors at Electronica – with 6.8µF/100V (V case) and D case 3.3µF/125V from its TCJ series.

Compared with 63 and 75V versions launched in the spring: “Maintaining 20% recommended voltage derating, TCJ series capacitors significantly extend the usable voltage range,” claimed the firm. “Reliability exceeds 1% per 1,000 hours at 85ºC and full-rated voltage.”

Applications are sought in 48V telecommunications equipment, line filters, TV dc-dc converters, notebook PSUs, and in industry.

“The capacitors solve the audible piezoelectric noise problems of LCD monitors, which generally use MLCCs and emit noise as a result of capacitance changes due to ambient temperature or voltage fluctuations. Tantalum capacitors don’t have this problem,” claimed the firm.

Halogen-free, the capacitors are sampling now with production from early 2013.
