Capacitor technology has environmental benefits
A new capacitor technology, OxiCap from AVX, offers a host of environmental advantages while delivering higher performance than other types of capacitor.
A new capacitor technology, OxiCap from AVX, offers a host of environmental advantages while delivering higher performance than other types of capacitor. More, these new devices use niobium oxide which, unlike tantalum is cheap and readily available - yet they can be manufactured on existing standard tantalum processing lines. One of the key advantages of the new NbO technology is its nonburn characteristics, which mean that failed devices are guaranteed not to burn up to the rated voltage.
With new initiatives designed to eliminate smoke, this is a major step forward.
AVX's OxiCap devices are also halogen free; another important environmental benefit is that they are compatible with lead-free directives.
None of these environmental benefits come at the expense of performance.
OxiCap capacitors exhibit reliability figures of 0.2%/kh, 2 to 5x better than comparable tantalum products, whilst remaining comparable on temperature stability, frequency response and electrical parameters.
Finally, OxiCaps need never be subject to supply constraints.
NbO material is readily available in large quantities and can be processed with minor modifications to the tantalum capacitor production line.
Even if NbO replaced all Tantalum production it would represent less than 10% of mined product as opposed to 70 to 80% of mined tantalum being gobbled up by the capacitor industry.
Typical applications include automotive, mobile phones, PDAs or any application that needs to seamlessly move to a lead free process or benefit from a higher performance alternative to aluminium and other SMT capacitor technologies.
Other features of these new AVX capacitors include: total traceability; reduced voltage derating; temperature rating up to 125C; rated voltage of under 10V and EIA case sizes that are the same as tantalum devices.
