Miniature tantalum capacitors save board space
The Matsuo 251 series of ultraminiature solid-electrolyte tantalum capacitors is now available exclusively in the UK from Surtech.
The Matsuo 251 series of ultraminiature solid-electrolyte tantalum capacitors is now available exclusively in the UK from Surtech. The new range is designed to meet the market requirements for minimising board space and maximising packaging density in handheld and portable electronic equipment. The key to the overall size reduction is the use of 'face down' terminals with an under-pad solder system that restricts the spread of solder to within the overall dimensions of the component, with no 'spill over'.
As a result, it has been possible to achieve volume reductions of 2.5 and weight reductions of 1.5 compared with earlier equivalent types.
The devices are available in 1608 size (1.6 x 0.85 x 0.8mm) and 2012 size (2 x 1.25 x 1.1mm) with voltage ratings of 2.5, 4, 6.3 and 10V DC and a capacitance range from 4.7 to 47uF.
Epoxy resin moulding is used, and operating temperature range is -55 to +125C.
