Summary of Specifications
Features
Telephone lines use a DC voltage of 48 volts and
pass the subscriber’s AC signal pulse of 15 to 25Hz,
at 70 to 90Vrms.
These MLCC Tip & Ring capacitors replace bulky
leaded film capacitors and offer excellent frequency
response, low ESR, and improved temperature
characteristics. Ideal for telecommunication and
modem applications.
Small size & high capacitance
Suitable for wave and reflow soldering
Surface mount
Low ESR characteristics & improved
temperature performance
RoHS compliant
