( Brand: Hammarlund ), ( Manufacturer Part Number: 11735-95 ), ( Model: HAMMARLUND SD2838 LC1679 11735-95 HS140 MC35S ), ( Part Type: Air Capacitor )
The Hamarlund 11735-95 is a vintage air capacitor, specifically designed for use in radio communication equipment. This capacitor, part number SD2838, is also known as the LC1679 and HS140 MC35S.
This Hamarlund capacitor is a non-polarized type, meaning it can be connected to the circuit in any orientation without causing damage. It features a rugged and durable design, with a metalized electrolytic film construction that provides excellent electrical performance and reliability. The capacitor has a capacitance value of 1,000 microfarads and is rated for a working voltage of 500 volts.
The capacitor's air dielectric provides several advantages over other types of capacitor designs. Air dielectrics have a very low loss factor, which means they do not dissipate energy as heat when an AC voltage is applied. This results in a very low impedance, making them ideal for use in high-frequency applications. Additionally, air capacitors have a very high voltage rating, which makes them suitable for use in high-voltage circuits.
The Hamarlund 11735-95 is a large capacitor, measuring approximately 9.5 inches long, 3.7 inches wide, and 3.5 inches high. It weighs approximately 12 pounds, making it a substantial component in any electronic circuit. The capacitor is sealed in a metal can with a vented top, which allows for the safe release of any internal pressure that may build up during operation.
The Hamarlund 11735-95 is a valuable addition to any vintage radio communication system or electronic project. Its high capacitance value and rugged construction make it an ideal choice for use in high-power RF circuits, such as those found in amateur radio transmitters and receivers. The capacitor's vintage design and historical significance also make it a prized collectible for radio enthusiasts and electronics hobbyists.
