High Capacitance Chip -
X7R, X5R
A range of High Capacitance value BME MLC chip capacitors, in stable
Class II dielectrics X7R and X5R, with a spread of capacitance values
offered up to 100µF.
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. As a consequence they are also 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.
Parts are RoHS Compliant and suitable for reflow soldering process.
