Upgraded Panel Pot Lives Long

The company has doubled the rotational life of its P30L compact panel potentiometers, which now deliver up to two-million cycles at their rated power. The potentiometers' power rating has also been increased from 2W to 3W. Other features include an operating torque of 4.25 oz.-in., an end stop torque of 99 oz. per inch, and a cermet resistive element. The potentiometer is available in four resistances values from 1 kΩ to 50 kΩ over a 44.7V to 300V working range with a ± 5 % independent linearity. Operating temperature ranges from - 40°C to + 125°C. Pricing for the P30L is $11 each in small quantities and $7 per unit in large quantities. VISHAY INTERTECHNOLOGY, INC., Malvern, PA.
