TT Electronics 7286 Series Precision Wirewound Potentiometer 100kΩ 7/8 Inch

The TT Electronics 7286 Series Precision Wirewound Potentiometer offers 100kΩ resistance with a 10-turn adjustment in a 7/8 inch bushing-mount design.

Overview

This wirewound potentiometer is designed for applications where accurate and repeatable control of electrical resistance is required. Its bushing-mount construction and 10-turn adjustment mechanism allow precise setting of resistance, while a screwdriver slot supports calibration and fine-tuning in fixed installations.

Key Features

• Linear track taper, giving a direct, proportional relationship between shaft rotation and resistance change
• Rated for 2W power handling
• Turret terminal type for electrical connections
• Resistance tolerance of ±5% and temperature coefficient of ±20ppm/°C
• Maximum backlash of 1° and maximum end voltage deviation of 0.25%
• Low maximum noise of 100Ω, supported by wirewound resistor technology
• Dielectric strength rated at 1000Vrms

Durability and Environment

The potentiometer has an operating temperature range of -55°C to 125°C and an IP50/IP66 protection rating, which provides defence against dust ingress and powerful water jets.

Dimensions and Weight

The potentiometer measures 43 mm in height, 33 mm in width and 15 mm in depth, with a weight of 21.225 g.

Applications

Suitable for precision circuits in industrial controls, test equipment, and instrumentation, as well as calibration and fine-tuning in fixed installations. Choose this potentiometer when a 100kΩ, 10-turn, linear-taper wirewound component with a 7/8 inch bushing mount is required.
