Notes:
FB1 and FB2 are ferrite beads. They work in conjunction with Capacitors C1 and C2 to eliminate EMI from the
telephone cable. Xecom recommends a TDK CB30-1812 surface mount ferrite bead because it provides over 100
ohms impedance at 100 MHz.
C1 and C2 ground any EMI signal present on Tip and Ring. Xecom recommends a Sprague 30GAT47 capacitor.
This is a 470 pFd capacitor rated for 3000 Volts. The high voltage rating is required to maintian the required
isolation barrier between the telephone line and ground.
RV1 is a solid-state protection device to reduce the likelihood of damage due to lightning strikes. RV1 works in
conjunction with the two 10 ohm resistors to protect the XE0016 circuitry. Xecom recommends the Teccor P3100
Sidactor for this function. Its typical breakover voltage of 310 volts prevents the XE0016 from being exposed to
voltage surges while being rated high enough to prevent being triggered by an incoming Ring signal.
