Murata has commenced the mass production of EIA 0805 2,0 x 1,25 mm size monolithic ceramic capacitors (MLCCs) using a 2 mm spacing of narrow pitch embossed tape. Compared to the previous 4 mm tape pitch that held 10 000 pieces, the new tape holds double the quantity. Not only is it more eco-friendly, but it also requires less reel changes on the pick-and-place assembly machine.
The EIA 0805 capacitor’s size and large capacitance values are extremely popular in many types of electronics appliances, and are used in large quantities. For example, a typical flat screen television may use approximately 650 chip capacitors, of which 20% use the EIA 0805 format. Using the old tape pitch, the reel would need to be changed every 75 televisions made. With the increased reel capacity it now only needs to be changed every 150 televisions manufactured, improving the efficiency of the production line and reducing costs.
In addition, manufacturers require less storage space within the warehouse for MLCC component stock and, for a given production quantity, there is less packaging waste to dispose of. Apart from adjusting production machinery settings to accommodate the new tape spacing, there are no additional machine tool costs for manufacturers taking advantage of this new tape pitch.
