Uses Analog lines and ISDN lines Features ・ The modular type can be easily installed because a modular cord is attached. ・ The LF-series filters attenuate common-mode noise in the range from 100 Hz to 10 MHz. ・ The filters can also be used to reduce inverter noise and other induction noise from power lines. ・ The filters are suitable to protect ISDN equipment because their insertion loss as measured on ISDN signals is as low as 1.5 dB max at 160 kHz. ・ Small and light. • Modular type (LF-MJS) • Example of characteristics in common mode Part number LF-MJS Type Modular Number of slits and number of wires 6 slits and 2 wires Rated voltage 55 VDC max (between lines) Rated current 120 mA DC max (in the direction of cancellation) Attenuation in common mode 30 dB min (1 kHz to 1 MHz) Attenuation in normal mode 1.5 kB max (160 kHz, 110 Ω) DC resistance 20 Ω max between lines Dielectric strength 250 VDC between lines for 1 minute Insulation resistance 10 MΩ min at 250 VDC between lines Operating temperature range -10 - +40 ºC
