Mica and PTFE CapacitorsMica and Polytetrafluoroethylene (PTFE) capacitors are specialized varieties of electrical capacitors designed to answer specific needs of high power applications that require precise capacitance and high stability. The MCH38FM151J-Y capacitor is one such component. It is developed for operating temperature from -55 degrees Celsius to +105 degrees Celsius and is suitable for use in power converters, drives and UPS systems as well as devices that demand low ESR and ESL values. Application FieldThe MCH38FM151J-Y capacitor is designed for medium power and medium-to-high frequency applications. It guarantees a very low ESR and ESL thanks to its layout, consisting of clean mechanized-pill (CM) mica capacitor technology. This ensures very high energy density levels and features a self-healing effect, meaning it discharges accidental mismatched over-voltages without need for replacement. Its medium power range means that it carries sufficient continuous power sufficient to operate in Portable Electrical and Electronic Devices (PEDS), Variable Frequency Drives (VFD), Inverters, UPSs, telecom/networking applications and high-end audio.Despite being primarily developed as one of the mica capacitor series, the MCH38FM151J-Y capacitor also boasts a very tolerant temperature range. This means it is suitable for use in low-temperature applications (-55^oC) and high-temperature ones (+105^oC). This capacitor series is often used in microcontrollers and other advanced devices that demand high capacitance at a consistently stable temperature.Working Principle The MCH38FM151J-Y capacitor is designed around the Electric Double Layer Capacitor (EDLC) technology. It is considered a hybrid type of capacitor that is capable of storing energy much like a battery, yet recharging rapidly like a classic capacitor. Its operating principle follows the n-SiFET structure, which ensures that the energy is converted and stored rapidly regardless of load shifts. The capacitance of an EDLC is dependent on the material used and the layout of the Plate and Electrolyte Assembly (PEA). The MCH38FM151J-Y uses Mica & PTFE combination and, with its enhanced design of the Metallized Pill Cap (MPC), provides outstanding capacitance for its size and weight. The capacitor also features a reverse-tolerance scheme. This means that its capacitance changes well within the error margin when the temperature or applied voltage shifts; and it often does not exceed the desired PD (Power Dissipation) target. This makes the MCH38FM151J-Y capacitor a good choice for applications requiring heavy load and larger capacitor count. Equally important are the additional features of the MCH38FM151J-Y capacitor. This includes the pressure relief design, meaning that it allows some gases to escape under pressure before its Scavenge Plate (SP) valve opens and circuit gets disconnected. The lifecycle of the capacitor also far exceeds industry-standard values. This is seen with its long-term aging, with no capacitance or loss shift occurring over time ConclusionThe MCH38FM151J-Y capacitor is an exceptional component designed for the most demanding high-power applications. It provides stability and reliability, and with its enhanced design of the Metallized Pill Cap (MPC), it allows for higher capacitance ratings. The added features of the pressure relief design and long-term aging ensures that it carries sufficient energy to ensure continuous operation in Portable Electrical and Electronic Devices (PEDS), Variable Frequency Drives (VFD), Inverters, UPSs, telecom/networking applications and high-end audio devices. Its reliability also helps to reduce total cost of ownership of the device.
