1 High attenuation of common mode noise NAC series Ordering information NAC O 2 4 Model Name 2Rated Current Line to ground capacitor code:see table.. This product will be released from Feb.6 table. Line to ground capacitor code Code Leakage Current ( 25/2V Hz) Line to ground capacitor (nominal value) A/ A max 6pF 2.mA/.25mA max pf mA/.5 ma max 2pF 2.8mA/.75mA max pf ma/. ma max 47pF * hen the line to ground capacitor code is different, the attenuation characteristic is different. 4Options D:DIN rail installation type * The dimensions change when the option is set. Refer to External view. Features of NAC series - High attenuation of common mode noise from khz to MHz - Single Phase 2 VAC - Quick and easy push-down terminal Just connect the wires, push down and tighten the screws with a screwdriver Specifications No. Items NAC NAC--472 NAC NAC--472 NAC--472 Rated Voltage[V] AC f 2 / DC2 2 Rated Current[A] 6 6 Test Voltage (-Mounting Plate) 2, VAC (Cutoff Current = ma), minute at room temperature and humidity 4 Isolation Resistance (-Mounting Plate) VDC M minute at room temperature and humidity 5 Leakage current 25/2V Hz.5mA/.mA max 6 Voltage drop.v max 7 Safety agency approval temperatures -25 to +85C (Refer to Derating Curve) 8 Operating temperature - to +85C (Refer to Derating Curve) 9 Operating humidity to 95%RH (Non condensing) Storage temperature/humidity - to +85C/ to 95%RH (Non condensing) Vibration to 55Hz, 9.6m/s 2 (2G), min.

5 Transmission 2 Application Precautions The following points should be kept in mind to use the noise fi lter more effectively. Electronic device 6 Electronic device wire and output wire of the noise fi lter should be separated. hen the input/output wire are bundled together or wired parallel 2 with each other, high frequency noise is induced so, and the expected effect of noise attenuation cannot be achieved. Electronic device wire wire transmission between electric power and electronic device wire wire Conducted noise from electric power lines. 2 Radiated noise which is picked up and generated by the power line as antenna. Conducted and radiated noise which is generated in the electronic device. 4 Conducted noise which is generated by the signal lines betweeen electronic devices. 5 Radiated noise emitted an electronic device that interferes with other device. 6 Radiated noise which is picked up and generated by the signal line as antenna. Good wiring example Bad wiring example Ground lines should be as short as possible. If it is not, an equivalent inductance appears, and the high frequency attenuation characteristics degrade. hen grounding the mounting plate of the noise fi lter, you should remove the paint to reduce the contact resistance from the equipment case, and then install the noise fi lter. 25
