Overview
| Mobile phones, MP3 players, and other portable devices The trend towards greater compactness, increased thinness, and higher
performance has created a demand for capacitors that integrate a larger capacitance in a smaller, lower profile form factor. |
 |
Features
- Ultra-compact package
60% smaller footprint and 70% smaller volume than our conventional 1608-sized TCM series
capacitors.
- High capacitace (2.2uF to 15uF) - ideal for coupling and noise reductio in audio circuits
- Underside electrode configuration utilized for high productivity and superior reliability
- Environmentally friendly halogen-free package

Comparison vs. Ceramic Capacitors (Ringing Problem)
Ceramic capacitors are susceptible to ringing during voltage changes due to the piezoelectric effects of the multilayer ceramic material, which causes the ceramic to vibrate.
Perhaps the most effective countermeasure to this ringing problem is to use tantalum capacitors.
Tantalum capacitors are not piezoelectric in nature, and therefore do not vibrate during voltage changes, resulting in no ringing.

 |
| Vibration of the ceramic capacitor itself, along with the substrate, result in audible ringing |
|
 |
| Tantalum capacitors do not vibrate during voltage changes. Therefore, no ringing occurs. |
|
In many instances this ringing problem is found during final set evaluation and must be quickly dealt with before it is shipped to the customer. Otherwise shipment delays and other problems will occur, making it imperative that this issue be resolved in a timely manner. |
Applications
Mobile phones, smart phones, portable audio, IC recorders, digital cameras, and other thin, compact electronic devices
