The CNF31 . CNH31 . CNH30 . CNH32 series is a 3-terminal EMI filter for SMT based on multilayer chip capacitor technology.
The CNH series is suited for reducing EMI noise on DC power lines.
 |
|
■ Features
|
• |
Due to its small size and low residual inductance, noise reduction is possible at higher frequencies than conventional capacitors. |
|
• |
High current rating (~2A), makes it well suited for reducing EMI noise on DC power lines. |
|
• |
High capacitance (0.1μF max.) enables reduction of noise over a wide frequency range. |
|
• |
Nickel and tin plated barrier terminations offer good solderability and resistance to soldering heat. |
|
• |
RoHS Compliant. |
|
■Applications
|
• |
Noise reduction for signal lines and DC lines in computers, computer peripheral equipment, digital TV, DVD recorder, cellular telephone,automotive electronics, printer, FAX, etc. |
