The potential for customers' cost reduction is not only in the unit price of the part! Murata supports cost reductions at a higher level through reductions in the number of parts of capacitors, etc.,utilizing the characteristics of ceramic capacitors to the maximum.
An example of reducing the number of capacitors from 10 general-purpose capacitors to 4 low ESL capacitors is introduced (quantity reduced is an example). Using low ESL capacitors, will realize a reduction in the number of parts, while maintaining equivalent functions. Murata also provides design support, if you are having difficulty determining the areas where the
While the price per part is continuing to fall, the ratio of tcustomers' mounting costs continues to rise.
Using low ESL capacitors will greatly reduce the mounting costs accompanying the reduction in the number of parts. The TOTAL costs including the part costs, mounting costs, overhead costs and other costs can also be reduced.
Using low ESL capacitors will reduce costs, particularly in locations where numerous bypass capacitors are arranged for the power supply pins of ICs.
For example, in the case of a set of 5 million per year, if the mounting cost per piece is \0.8, approximately \36 million can be reduced per year with the conditions in the following table.
When the number of capacitors currently being used, the mounting cost per capacitor and the number of sets (yearly) are entered, the cost reduction using low ESL capacitors can be simulated. This is the reference value of the price per part. Please contact Murata for the actual price per part, or calculate based on the price per part currently being used.

In addition, low ESL capacitors contribute to a reduction of the mounting area, resulting in compact The figure on the left is an example of reducing the bypass capacitors around a CPU, from 10 general-purpose capacitors to 4 low ESL capacitors. In this example, 10% of the mounting area could be reduced while maintaining equivalent functions by using low ESL capacitors.

Replacement evaluation of electrolytic capacitors is demonstrated.Extensive improvements in the characteristics and low profiles can be achieved, by replacing electrolytic capacitors with conductive polymer capacitors or monolithic ceramic capacitors.
The replacement evaluation of low acoustic noise capacitors is demonstrated. The acoustic noise phenomenon occurs in some cases due to the piezoelectric properties of ceramic. In order to solve this, Murata has developed a low acoustic noise capacitor! Click here to experience the effectiveness of the low acoustic noise capacitors of Murata.
