Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs) – Telecom "Tip and Ring,” X7R Dielectric, 250VDC, (Commercial Grade)
Electrical Parameters/Characteristics
Regarding Aging Rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1000 Hours.
To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.
Capacitance and Dissipation Factor (DF) measured under the following conditions:
Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 & Agilent E4980 have a feature known as Automatic
Level Control (ALC). The ALC feature should be switched to "ON".
