( Brand: Western Electric ), ( Model: 470A )
The Western Electric 470A is a vintage diode that holds a significant place in the history of electronics. Manufactured by the iconic Western Electric Company, this diode is a testament to the engineering prowess of the past.
The Western Electric 470A is a rectifier diode, designed to convert alternating current (AC) into direct current (DC). It operates on a principle known as the rectification of AC, which is fundamental to the functioning of numerous electrical devices. The diode allows the flow of current in one direction only, thereby filtering out the AC component and providing a steady DC output.
The 470A diode is known for its robust construction and high reliability. It is made with a high-quality germanium material, ensuring a long service life and excellent performance even under high power conditions. The diode's glass encapsulation provides protection from environmental factors such as moisture and dust, ensuring its longevity.
The Western Electric 470A diode has a nominal forward voltage drop of around 0.35 volts at a forward current of 100 milliamperes (mA). It can handle a maximum forward current of 100 milliamperes and a maximum reverse voltage of 250 volts. These specifications make the 470A diode suitable for use in a variety of applications, including power supplies, audio circuits, and vacuum tube amplifiers.
In terms of physical dimensions, the Western Electric 470A diode is approximately 1.7 inches long and 0.6 inches wide. It has a screw-on base with three lugs, which allows for easy installation in various electrical circuits. The diode's glass top is marked with the Western Electric logo, the part number 470A, and the value "1A" to indicate its maximum forward current rating.
The Western Electric 470A diode is a classic piece of electronic hardware, cherished by electronics enthusiasts and collectors. Its vintage appeal, coupled with its exceptional performance and durability, makes it a valuable component in many restoration projects and DIY electronic projects. Whether you're a hobbyist, a historian, or a professional electronics engineer, the Western Electric 470A diode is a must-have in your collection.
