New multi-anode mirror design TPM tantalum capacitors from AVX feature lowest ESR

The D sized TPM 47µF/25V part offers the lowest ESR in industry - just 55mΩ. In comparison, a single anode part in the same package has an ESR of 100mΩ and the E case device (same footprint, bigger case size) the minimum ESR is 80mΩ. Therefore, by reducing ESR 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.

Also new in the TPM range, AVX has now released the first mirror design multi-anode parts rated at 35V. TPM 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 especially suitable for automotive battery applications running on 12/14V with very low impedance, where it also offers greater robustness and lower ESR than single anode capacitors. More, since 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. For higher operating voltages the TPM D 10µF/50V with an ESR of 140mΩ is also available.

All parts meet the requirements of AEC-Q200, which is a key requirement for automotive designs in Europe.
