Niobium oxide capacitors go smaller and
thinner
OxiCap niobium oxide capacitors are now also available in smaller and thinner packages in response to demand in mobile phones, digital cameras and thin notebooks and PDAs.
AVX's recently introduced technology breakthrough, OxiCap niobium oxide capacitors are now also available in smaller and thinner packages in response to demand in mobile phones, digital cameras and thin notebooks and PDAs The devices are compatible with the latest lead-free directives, are RoHS compliant, halogen-free and carry the coveted Sony Green Partner award

ZIF connectors lock securely
Locking feature prevents accidental removal of the cable in the field and delivers uncreased robustness against vibration.
High-frequency capacitors cut stray inductance
Medium-power devices are targeted at situations where standard capacitors cannot handle the high-frequency ripple currents experienced.
Launched at the beginning of the year, niobium oxide capacitors offer a wide range of benefits.
Key to the success of this technology is its safe failure mode, which means that in the event of critical damage to the device, it will not burn up to the category voltage.
With new initiatives designed to eliminate smoke, this is a major step forward.

IDCs take on powerful duties
Connectors handle up to 15A and are rated for use at up to 650V, suiting them for use in applications such as high voltage inverters in the lighting industry.
Tantalum capacitors have thin-film fuses
Unlike conventional devices that incorporate a lead wire fuse, TAW series tantalum capacitors are fully lead-free and RoHS compliant.
On top of all the environmental and safety benefits offered by OxiCap, performance is comparable or better than other technologies.
Reliability figures are better than 0.2%/kh, which is 2 to 5 times better than comparable polymer products, while remaining comparable on temperature stability, frequency response and electrical performance.
In smaller packages NOS OxiCap capacitors feature lower profiles and are available in heights of 1.2, 1.5 and 2.0mm.
Where height is a major constraint such as in wireless cards, clamshell phones, wireless notebooks, slim cameras and single sided board designs, then these offer an attractive solution.
Where space is constrained the smaller packages available such as the new offerings in the 0805 package (2.0 x 1.25mm) will be welcomed.
Providing similar levels of capacitance and voltage as their larger offerings, these new devices allow designers opportunities to downsize their package solutions.
Low ESR NOS capacitors are rated up to 125C, and a range of newly released conventional and multi-anode (NOM Series) low ESR capacitors have been developed for high frequency power filtering applications.
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 (20% is sufficient); temperature rating up to 125C; rated voltage of under 10V; and EIA case sizes that are the same as tantalum and polymer devices.
Finally, NbO material is readily available in large quantities and can be processed with minor modifications to the tantalum capacitor production line, offering customers a hedge against future supply concerns as has been the case with tantalum in the past. Request a free brochure from AVX ...
