MULTILAYER CERAMIC TIP & RING APPLICATIONS

FEATURES

• Telco Capacitor. This type exclusively for Tip & Ring and

ring detection circuts as STD Telecom filter to block -

48VDC telephone line voltage and pass subscribers AC

signal (16Hz ~ 25Hz, 70Vrms ~ 90Vrms).

• Save board space.

• Surface Mount (EIA Sizes) packages.

• Low ESR.

• Wide band operation, excellent high frequency Telecom

filtering.

• Available in X7R.
