Mica and PTFE capacitors are an important part of any electronic component inventory. CMR03E750JOAM capacitors are a very small, high capacity and high voltage unit used for a variety of applications. The combination of mica and Polytetrafluroethylene (PTFE) results in an incredibly versatile and reliable capacitor.

The main applications of the CMR03E750JOAM capacitor are widespread and include:

• Power Supply & Filtering: CMR capacitors are used in filtered power supplies and switching supplies to protect against voltage spikes, protect against over-voltage, reduce ripple and improve EMI suppression.
• RF shielding & Coupling: Due to its high capacitance to volume ratio, CMR capacitors are used in RF shielding and coupling to transfer energy from one circuit to another without crosstalk.
• High Voltage DC-DC Converters: CMR capacitors are regularly used in high-voltage DC/DC converters to prevent voltage spikes and reduce energy losses.
• DC Transformer: CMR capacitors are prevalent in DC transformer applications, as the capacitors it uses must meet very strict voltage and environmental requirements.
• Motor Control: CMR capacitors are used in motor control to reduce electromagnetic interference and to provide an additional filtering function.
• Lighting Ballasts: CMR capacitors are used in lighting ballasts to reduce spark and arc effects and to further improve noise filtering.

CMR03E750JOAM capacitors have been designed to offer unparalleled performance when operating in high voltage applications, and they can withstand up to 750 volts of direct current. These capacitors are capable of handling peak voltages of up to 1000 volts, an impressive feat for such a small device. Designed to be used in a wide range of applications, CMR capacitors are also incredibly robust, being able to handle temperature ranges of -55 to +125 degrees Celsius.

The operating principle of CMR03E750JOAM capacitors is straightforward; they are a dielectric capacitor featuring a mica dielectric that is sandwiched between two electrodes. When an electrical signal passes through the capacitor, a thin layer of PTFE separates the two electrodes and prevents them from coming into contact. This process creates an electric field between the two electrodes, allowing the capacitor to store energy. This process enables the capacitor to store a large amount of energy for a short period of time and then release it again.

CMR03E750JOAM capacitors offer an extremely reliable, durable solution for a wide range of applications. Their small size, high capacitance and high voltage capabilities make them an ideal choice for applications such as power supply filtering, RF shielding and coupling, high voltage DC-DC converters, motor control and lighting ballasts. Their robust construction allows them to operate reliably in a wide temperature range, ensuring that they remain reliable even in the most demanding of environments.
