Designed for All Critical Applications
As pioneers in the use of Polypropylene as a capacitor dielectric, Electronic Concepts, Inc. has designed a full line of polypropylene and metallized polypropylene precision capacitors.
Among these in type PT12 polypropylene precision capacitors which exhibit unique and outstanding electrical and environmental characteristics.
The following are some of the most significant.
- Negligible shift in capacitance under long term exposure to humidity, operating life and temperature cycling.
Insulation resistance, dielectric absorption and dissipation factor properties are all equivalent, or superior, to those of polystyrene.
These polypropylene capacitors are designed for use from -55°C to +105°C without derating. Therefore, type PT12 can be used in high temperature applications when it is not feasible to use polystyrene capacitors(which have an upper limit of 85°C).
Polypropylene capacitors are excellent for all critical applications which require high insulation resistance, high Q, extreme stability, close tolerance, low dielectric absorption and dissipation factor. The temperature coefficient makes an excellent choice for high Q tuned circuits, precision filter circuits, pulse networks and RC circuits.
