AVX: 55mΩ Part Can Replace Two Devices in Some Designs

From AVX Press

AVX Corporation, a leading manufacturer of advanced passive components and interconnect solutions, has expanded 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 -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) provides a minimum ESR of 80mΩ. 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 ideal 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. 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.
