High Capacitance Chip X7R & X5R
A range of High Capacitance value BME MLC chip capacitors, in
stable Class II dielectrics X7R & 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.
