CIE Components in Electronics
DMTL, a design-in distributor that specialises in passive components, is now stocking the highest rated voltage tantalum capacitors currently available on the market. Produced by AVX, the new TCJ Series 100V and 125V surface-mount chip capacitors provide capacitance and ultra-low ESR in a compact case size (2924 for the 100V device).
According to DMTL, the new capacitors allow design engineers to reduce the number of components on the board, providing much greater layout flexibility than comparable aluminium electrolytic capacitors which, in turn, allows for more compact end-product designs.
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 as well as a host of industrial applications.
TCJ series capacitors also feature a benign failure mode eliminating ignition failures that can occur in standard MnO2 tantalum technology. This increases robustness, and reduces any tendency to overload or burn. Subjected to strict ageing and screening processes to ensure that all parts demonstrate the highest reliability, the capacitors maintain high reliability exceeding 1% per 1000 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. DMTL can supply them in 7in and 13in pure tin reels.
