The CNF20 series is an extremely small (2.0x1.25) 3-terminal chip capacitor. It is well suited for reducing EMI noise.
 |
|
■ Features
|
• |
Due to its small size and low residual inductance, it performs noise reduction at higher frequencies than conventional capacitors. |
|
• |
An optimum constant can be selected according to the frequency from the 22-2,200 pF capacitance range. |
|
• |
Nickel and tin plated barrier terminations offer good solderability and resistance to soldering heat. |
|
• |
RoHS Compliant. |
|
■Applications
|
• |
Noise reduction for computers, computer peripheral equipment, digital TV, digital VTR, cellular telephone, automotive electronics, etc. |
