Dear Experts
Regarding the recommended decoupling capacitor value for the LX2160A,
AN5407 states the following:
Note: All capacitors must have a rated voltage of 6.3V or higher and be 0402 size. All capacitor capacitance should be evenly distributed across the power rail pins and not closely packed.
Does this 6.3V value take into account DC bias characteristics?
Can I assume that a 4V product with excellent DC bias characteristics (e.g., Murata Manufacturing's GRT155D70G106ME13) can also be used?
Dear @kurokawa ,
I hope you are doing well.
Regarding your questions:
>> Does this 6.3V value take into account DC bias characteristics? ans. yes.
>>Can I assume that a 4V product with excellent DC bias characteristics (e.g., Murata Manufacturing's GRT155D70G106ME13) can also be used? ans. Yes, it could be used, in theory, but the rule is to use capacitors with a nominal voltage 2x or 3x higher than the real rail voltage. That's why, NXP recommends to use capacitor at 6.3V.
Unfortunately, NXP doesn't have any documented lab measurements test for the Murata GRT155D70G106ME13 in order to be able to say YES or NOT as fact.
thanks for your comprehension.
