Mica and PTFE capacitors are generally used in applications where linear capacitance and temperature stability are both necessary. The CMR04E270GODM is a popular capacitor as a member of the Mica and PTFE capacitor family due to its exceptional performance in terms of high dielectric breakdown voltage, low ESR and ESL, good high frequency characteristics, good solderability, and low parasitics.The CMR04E270GODM capacitors are non-inductive, molded polypropylene capacitors in surface mount packages. They have a temperature range of -55°C to +125°C. The capacitors are constructed with a ceramic core with mica dielectric layers and a PTFE insulation layer. The capacitor’s casing is molded from a high-temperature-resistant polypropylene and is hermetically sealed for maximum longevity. The CMR04E270GODM works by storing an electrical charge on two metal plates which are separated by an insulating material. The capacitance of a capacitor is measured in Farads, and is determined by the surface area of these metal plates, their separation distance, and the type of dielectric material used. In the CMR04E270GODM, the dielectric is a combination of mica and PTFE, which provides an exceptionally high dielectric breakdown voltage. This means that the capacitor can cope with larger surges without failing catastrophically. The CMR04E270GODM is commonly found in temperature-sensitive circuits such as amplifiers, switches, PLLs, voltage detectors, and oscillators. Its main advantage lies in its zero aging characteristics, meaning that it maintains its capacitance relative to temperature. This ensures that a circuit’s sensitivity and accuracy can be maintained even if temperature changes occur. In addition, the capacitor has an excellent high frequency performance and low inductance, making it an excellent choice for a wide range of high-frequency applications.The main disadvantage of the CMR04E270GODM is that it is relatively expensive. Compared to other capacitors in the Mica and PTFE family, the CMR04E270GODM is not the cheapest option, but it is worth the additional cost for its superior performance.Overall, the CMR04E270GODM is a reliable and high-performance capacitor that is suitable for a wide range of applications. Its excellent resistance to temperature changes and high dielectric breakdown voltage makes it an ideal component for temperature-sensitive circuits. The relatively high cost of the capacitor is offset by its impressive performance and longevity.
