Fused tantalum capacitors from AVX protects against short circuits

News Release from: AVX

AVX's new TAW series fused tantalum capacitors protect against damaging high DC leakage currents at high currents. Short circuit failure mode protection is accomplished using an internal fuse connected in series with the capacitor. More, as the fuse is fabricated using thin film technology, these components are very reliable, ultra-fast and the lowest ESR commercially available fused tantalum capacitors currently available.

When the fuse exceeds its current limit, the fused capacitor will fail safe by effectively removing itself from the circuit by creating a high resistance path of above 10MΩ. In some cases this can mean the difference between a total circuit loss and barely detectible performance degradation.

Unlike conventional devices that incorporate an embedded lead wire fuse, the TAW series tantalum capacitors are fully lead-free and RoHS compliant. High-reliability applications such as aerospace, automotive, servers and telecoms infrastructure products will benefit from their new, improved design.
