( Brand: Sprague ), ( Manufacturer Part Number: 4TM-P20 ), ( Part Type: Capacitor ), ( Country Of Origin: United States )
The Sprague 4TM-P20 2x2uf 400V NOS Beauty Capacitor is a premium electrolytic capacitor designed for use in various electronic applications that require high voltage and large capacitance values. This capacitor is manufactured by Sprague, a renowned name in the electronics industry, known for its high-quality capacitors.
The 4TM-P20 model is specifically a 2-section, 2 microfarad (2uf), 400 Volt capacitor. The capacitance value of 2 microfarads indicates the ability to store 2 microcouloumbs of charge when a voltage of 1 volt is applied across the capacitor. The 400 Volt rating, on the other hand, signifies the maximum voltage that can be safely applied across the capacitor without risking damage or failure.
This capacitor is a NOS (New Old Stock) item, which means it is an unused, original piece that has been in storage for an extended period. This makes it an excellent choice for those seeking authentic, high-quality components for vintage or specialized electronic projects.
The 4TM-P20 capacitor is constructed using the "beauty" or "film" capacitor technology. In this design, the capacitor is made of a thin aluminum or tantalum foil rolled into a cylindrical shape and coated with a dielectric material. The foil layers are then rolled into a compact spiral, and the entire assembly is enclosed in a protective can. This design offers several advantages, such as low ESR (Equivalent Series Resistance), high ripple current handling, and excellent stability over a wide temperature range.
The Sprague 4TM-P20 2x2uf 400V NOS Beauty Capacitor is a versatile component suitable for a variety of applications, including power supplies, filters, and decoupling circuits. Its large capacitance value and high voltage rating make it an ideal choice for powering and stabilizing high voltage electronic systems.
In summary, the Sprague 4TM-P20 2x2uf 400V NOS Beauty Capacitor is a high-quality, large capacitance, and high voltage electrolytic capacitor designed for use in various electronic applications. Its NOS status ensures its authenticity and makes it a perfect fit for vintage or specialized projects. The beauty capacitor technology used in its construction offers excellent performance, stability, and reliability.
