Tantalum capacitors include thin film fuses

New solid tantalum capacitors incorporate an internal thin-film fuse delivering safety, consistency, reliability, compactness and significantly lower ESR than other commercially available devices.

New TBW solid tantalum capacitors from AVX incorporate an internal thin film fuse delivering safety, consistency, reliability, compactness and significantly lower ESR than other commercially available fused solid tantalum devices.

Because of their inherent reliability, tantalum capacitors are increasingly specified for use in harsh operating conditions.

However, in such applications, operating guidelines may be exceeded and devices may fail.

For example, if excessive transients are prevalent there is a possibility that the device may overheat and even burn.

This is exacerbated at high voltages where there is sufficient energy to overcome the natural self-healing properties of tantalum devices.

The new TBW fused solid state capacitors eliminate this possibility.

More, many applications require low ESR and have high current demands.

Any fuse has a resistance so, when coupled with the natural ESR of the capacitor, ESR levels for the combined part will exceed that of stand alone capacitors.

The fuse resistance of AVX's TBW series devices is typically half that of conventional fuses.

With a capacitance range between 4.7 and 47uF and a rated voltage up to 50V, TBW capacitors have an operating temperature range of between -55 and +125C.

Devices also comply with the low impedance requirement of MIL-PRF-55365 Weibull grading.
