TPM Tantalum Capacitors Reduce ESR Value by 30%

AVX Corporation has expand its TPM Series of multi-anode mirror design tantalum capacitors that offer improved robustness and feature low ESR including the industry's leading performance device. The D sized TPM Series 47µF/25V part offers the lowest ESR in the industry at 55m. In comparison, a single anode part in the same package has an ESR of 100m and the E case device (same footprint, bigger case size) provides a minimum ESR of 80m. By reducing the ESR value by 30%, the new capacitors offer a significant improvement in filtering capability, even to the extent that one part can sometimes replace two standard single anode devices. AVX has developed the first mirror design multi-anode parts rated at 35V. The TPM Series D 22µF/35V is suitable for use in circuits with high current and voltage spikes where the profile is limited to just 3mm. It is suited for automotive battery applications running on 12/14V with low impedance, where it offers enhanced robustness and lower ESR than single anode capacitors. In addition, since the D and E case sizes use an identical footprint, the pad design does not need to be changed if the D-case part can be used to replace the larger capacitor.
