Common capacitance value errors are caused by the low impedance of high capacitance MLCCs, often resulting to greatly reduce the test signal across the device under test (DUT). • TEST EQUIPMENT: Agilent HP4284A Precision LCR meter o This LCR meter has “ALC” automatic level control feature that compensates for DUT loading o If “ALC” function is disabled, the DUT impedance can be seen to greatly reduce the test level and result in incorrect capacitance measurement o EXAMPLE: 10uF MLCCs … NIC P/N: NMC1206Y5V106Z10 or NMC0805X5R106K6.3 o Test Level set at 1.0Vrms o With ALC OFF, test level drops to 0.2Vrms upon DUT insertion and incorrect capacitance measurement of “7.24uF” o With ALC ON , test level is maintained at 1.0Vrms upon DUT insertion and correct capacitance measurement of “10.08uF” RECOMMENDATION: • Monitor (measure) and adjust test level to achieve correct test level across DUT, see EIA-198-1F test conditions table above. • For guidance, please contact NIC technical support personnel [email protected] ISO 9001–2000 REGISTERED
