Taiyo Yuden Inc. has launched its new AMK105BJ475MV multi-layer ceramic capacitor (MLCC) for decoupling power-line circuits in high-performance ICs used in cellphones, digital still cameras and other battery-powered portable electronics.

The AMK105BJ is the first MLCC to achieve a capacitance rating of 4.7?F in the 1mm x 0.5mm x 0.5mm (EIA 0402) case size. The capacitor allows designers to obtain the desired capacitance value from a single 0402-size device, where two 2.2?F-rated 0402 capacitors were previously required. This saves cost and simplifies manufacturability by reducing parts count by 50 percent for this application. The AMK105BJ also allows designers to downsize from 0603 size components (1.6mm x 0.8mm x 0.8mm) to the more compact 0402 size, resulting in space savings without sacrificing device performance.

Moreover, the considerable size reduction of the AMK105BJ effectively doubles available capacitance for the same component mounting area. The benefits to the OEM are more compact, higher-performance equipment through reduced number of components, increased mounting density and higher capacitance.

Additional features of AMK105BJ include 15 percent capacitance change; 10 percent tangent of loss angle; -55C to 85C temperature range, 4Vdc rated voltage, and is RoHS compliant.

The AMK105BJ475MV is available in volume quantities at a sample price of 15 cents each in OEM quantity. Delivery is four weeks ARO.
