CHIP TYPE EMI FILTERS [ CNX41 ¥ CNG41 Series ]
The CNX41 . CNG41 series is a 3-terminal SMT EMI filter based on multilayer chip capacitor technology.
a Features
• Due to its small size and low residual inductance, it performs noise reduction at higher frequencies than conventional capacitors.
• The CNX . CNG series high current rating (~6A) makes it well suited for reducing EMI noise on DC power lines.
• The CNX series high capacitance (~1.5F) enables reduction of noise over a wide frequency range.
• High current priority and high frequency characteristic priority can be used properly in the CNG series.
• Nickel and tin plated barrier terminations offer good solderability and resistance to soldering heat.
• RoHS Compliant.
a Applications
Noise control for . the digital video signal lines in TV,VTR,DVD . computers and computer peripheral equipment . automotive
electronics . DC lines in printer ,FAX,etc.
