The SM501-1 Telecom Transformer from Datatronic Distribution is suitable for a wide range of BS6305 Impedance Class A non-speech data and Class B voice applications in telecom equipment, laptops, modems and instrumentation. Its dielectric strength is tested to 4600 Vrms and meets various international safety standards including UL60950-1. The SM501-1 Transformer provides space-efficient isolation between sensitive electronics and telephone lines. Its high dielectric strength helps safeguard equipment users by protecting them from electrical shock. The SM501-1 Transformer’s symmetrical design means that there is no real primary or secondary winding. Key specifications include impedance at 600 ohms (both primary/secondary), turns ratio is 1:1, 3.8 H shunt inductance and 6 to 7 mH leakage inductance at 1 kHz.
