Line-up of 1206 and 1210 packaged MLCCs rises above 100uF
Additions to its GRM Series of 1206 and 1210 size monolithic ceramic capacitors (MLCCs), above 100uF, have been announced by Murata.
As the functionality of electronic devices become more advanced and the available enclosure space becomes even more constrained, there is a growing need for capacitors that are both miniature and have a high capacity. Traditionally, polymer capacitors have been used above 100 uF since such high capacitance values have not been available. MLCCs deliver much better ESR characteristics than polymer capacitors and are more compact, so now that higher values are available MLCCs can aid to overall space reduction.
The GRM series 1206 size additions include 150uF and 220uF capacitors. Both these have a rated voltage of 6.3V. The slightly larger 1210 size adds a 330uF MLCC to the series with a rated voltage of 4V. All three new devices have an M (+/20%) deviation rating and X5R temperature characteristics such that the capacitance change is no more than +/-15% within a temperature range of -55C to +85C.
Typical applications include decoupling on low voltage rails for programmable logic and processors such as used in servers, network and data communications infrastructure.
