The CMR04C7R0DODM (also known as 04C7) is a mica and polytetrafluoroethylene (PTFE) capacitor used in a wide range of technologies. It is a high-quality capacitor that is both physically and electrically compatible with numerous electrical applications, from DC to microwave frequencies. The 04C7 is produced by a leading US-based company and is widely considered state-of-the-art in this market segment.

Mica and PTFE capacitors are most commonly used for RF and microwave applications. It is an ideal choice for low-voltage and high-frequency applications, where a small form factor and high insulation resistance are required. This type of capacitor is preferred for its low capacitance drift and minimal thermal dependencies. The combination of mica and PTFE makes the 04C7 exceptionally stable across temperature ranges, and makes it suitable for reliable use in military and aerospace applications.

The 04C7 can be used as an oscillator, a buffer, a differential amplifier, or a wide range of other applications from circuit filtering to signal generation. The device’s high stability makes it particularly suitable for use in oscillators, where fluctuations in operating conditions cannot be tolerated. The capacitance range of this part exceeds 20pF up to 200pF, making it versatile for a wide variety of electrical systems.

The working principle of the 04C7 is the same as other mica and PTFE capacitors, relying on a combination of mica and PTFE layers that are put into contact with each other under pressure. This creates a structure that enables the capacitance to remain largely constant under any temperature variation. The 04C7 is made from two electrodes, usually platinum or silver, and nonconductive mica weather layers, and are then filled with an electrolytic compound typically based on a mixture of polytetrafluoroethylene (PTFE) and powder.

The high insulation resistance and low loss of temperature performances of the 04C7 enable it to be used in harsh environments that require low ESR and high reliability. Additionally, it has superior seismic characteristics, can resist moist heat aging, and has excellent humidity and temperature stability, making it suitable for a range of highly demanding applications.

In conclusion, the CMR04C7R0DODM is one of the most reliable mica and PTFE capacitors on the market. Its high insulation resistance and excellent long-term performance make it an ideal solution for a wide range of applications, from low-voltage DC to high-frequency microwave frequencies. It is well-suited for use in military and aerospace projects, and provides the consistent performance required for demanding operating conditions.
