| NPO DIELECTRIC - GENERAL SPECIFICATION |
| INTRODUCTION |
| The NPO (COG) is a high Q, low K temperature compensating type of dielectric with stable electrical properties under varying voltage, temperature, frequency and time. It's suitable for circuits that require low lost, as well as timing and tuning applications. |
|
| FEATURES |
- Very low temperature coefficient
- Stable electrical characteristics
- Small size with high capacitance values
- Consistent dimension and finish surface
- Engineered for automatic handling and insertion
