Description

470 pFd, minimum 1500 Volts; these capacitors may be required for EMI filtering to prevent

unintended radiation when the telephone cable is attached to your system. These capacitors must be

rated at a minimum of 1500 volts to maintain the isolation required by FCC Part 68 Rules.

FB1 and FB2 are ferrite beads which may be required for EMI filtering to prevent unintended radiation

when the telephone cable is attached to your system. Cermetek recommends the TDK ACB2012L-

120 which provides more than 100 ohms impedance at frequencies above 100 MHz.

MOV1 protects against damage from lightening strikes on the telephone lines. Cermetek

recommends the Teccor P3100BA Sidactor to provide this protection.

F1 and F2 prevent damage to the system when a power line crosses with the telephone line.

Cermetek recommends the Raychem TR600-150 for this function. The TR600-150 is a PTC device

which automatically resets after use.
