Description

Cap. 1000 pfd, 1500V minimum

PTC, TR600-150

Notes:

1 Capacitors, C1 and C2, may be required for EMI filtering in your system. Without these components

you may experience unintended radiation when the telephone cable is attached. C1 and C2 are high-

voltage capacitors. We recommend the Johanson Dielectrics 502S47N102KV6T. This 1000 pfd, 3000

volt capacitor will direct the high frequency harmonics to the system ground. These capacitors must

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

3. F1 is a positive thermal coefficient (PTC) device which protects the modem from excessive current

flow. These devices are required for your system to pass UL60950. Fuses may be used in place of

the PTC’s
