The Mallory Gem-6147 is a high-performance capacitor specifically designed for industrial and commercial applications. This capacitor, manufactured by Mallory Electronics, is identified by the model number 6147 and production number 047. It is designed to operate at a voltage rating of 600 volts.
The Mallory Gem-6147 is a ceramic capacitor, which means it utilizes a ceramic material as its dielectric. Ceramic capacitors are renowned for their excellent stability, high frequency response, and ability to withstand high voltages. This particular model is a non-polarized capacitor, allowing it to be connected in various orientations without affecting its performance.
This capacitor has a capacitance value of 47 microfarads ( F), which signifies it can store 47 microcoulombs of electrical charge at a given voltage. The tolerance of this capacitor is /-20%, meaning the actual capacitance value could be anywhere between 37.6 F and 57.4 F.
One of the key features of the Mallory Gem-6147 is its high ripple current capability. It can handle a ripple current of 6.3 amperes (A) at a temperature of 25 degrees Celsius ( C). Ripple current is the alternating current that flows through a capacitor in addition to the DC voltage it is designed to store. This feature makes this capacitor ideal for use in power supply circuits where a steady voltage is required.
The Mallory Gem-6147 is designed with a temperature range of -55 degrees Celsius (-67 degrees Fahrenheit) to 125 degrees Celsius ( 257 degrees Fahrenheit). This wide temperature range allows it to function effectively in various environments, ensuring reliable performance in industrial applications.
This capacitor also features a self-healing voltage rating of 1050 volts. Self-healing refers to the ability of the capacitor to recover from short-term overvoltage conditions without sustaining damage. This feature is crucial in industrial applications where voltage spikes may occur.
The Mallory Gem-6147 is available in various sizes and configurations, including axial leaded, radial leaded, and cylindrical. The physical dimensions and weight of the capacitor may vary depending on the specific configuration chosen.
In summary, the Mallory Gem-6147 is a robust and reliable capacitor designed for industrial and commercial applications. Its high voltage rating, large capacitance value, and high ripple current capability make it an excellent choice for power supply circuits and voltage stabilization applications. With its wide temperature range and self-healing feature, the Mallory Gem-6147 is a versatile component that can withstand various operating conditions.
