The Clarostat SM-B-179-277 400 audio taper potentiometer is a high-quality component designed for use in various audio applications. This potentiometer features a linear taper design, which ensures that the resistance between the wiper and each terminal increases or decreases at a constant rate as the potentiometer is rotated. This makes it an ideal choice for applications where precise volume control or resistive divider functions are required.
The Clarostat SM-B-179-277 potentiometer comes with a carbon composition resistive element, providing a warm, musical sound that is preferred by many audio enthusiasts. Theusa-made part comes with a 1/4-20 threaded chassis mounting shaft and includes a nut and washer for easy installation. The potentiometer is rated for a maximum power of 400 watts at 125 degrees Celsius, making it suitable for use in high-power audio systems.
This potentiometer has a total resistance value of 277KOhms, with a nominal resistance value of 250KOhms between the wiper and each terminal. The wiper diameter is 0.5 inches, and the shaft height is 0.8 inches. The potentiometer has a frequency response of 10 Hz to 30 MHz, ensuring that it can handle a wide range of audio frequencies.
The Clarostat SM-B-179-277 400 audio taper potentiometer is known for its durability and reliability, with a Teflon bushing to minimize noise and wear in the shaft. It is also rosin-core buttered for smooth rotation and long-term stability. The potentiometer is RoHS compliant and comes with a 95% attendance factor, meaning that 95% of the resistance value is available between the wiper and each terminal, leaving only 5% for the wiper itself.
In summary, the Clarostat SM-B-179-277 400 audio taper potentiometer is a high-performance, high-quality component suited for audio applications where precise control and durability are essential. Its linear taper design, carbon composition resistive element, high power rating, and wide frequency response make it a versatile choice for various audio systems. The potentiometer's Teflon bushing, rosin-core buttered shaft, and 95% attendance factor ensure long-term reliability and consistent performance.
