Medical and military applications, where a high capacitance value is required, can consider the Novacap branded MLCCs (multilayer ceramic capacitors) from Knowles Precision Devices (KPD). According to the manufacturer, comparable circuit designs can be achieved at typically a third to a fifth of the capacitance values because of the low ESR characteristics these parts exhibit.
These RoHS-compliant, high-capacitance value BME MLC chip capacitors are manufactured in stable Class II dielectrics X7R and X5R. The range is offered with a spread of capacitance values starting at 6,8 nF and topping out at 100 µF. Because of the extremely low ESR characteristics, they are ideal to replace tantalum and low-ESR electrolytic capacitors without polarity concerns.
They find application as power supply bypass capacitors, smoothing capacitors, input/output filters in DC-DC converters and in digital circuits and LCD modules. ±10% and ±20% capacitance tolerances are available, and all parts are available with high-reliability screening.
Nickel Barrier termination options include tin, tin/lead or gold flash – all suitable for reflow soldering process. The gold flash option is of particular interest to eliminate the problem of tin ‘whiskering’. This sort of failure can represent a clear and present danger, especially to Hi-Rel applications such as medical implantable devices and military equipment.
