VISHAY 249 Series PCB Mount Cermet Potentiometer 100kΩ 1W

VISHAY 249 Series PCB Mount Potentiometer provides 100 kΩ track resistance and a 1 W power rating, with single-turn adjustment via a screwdriver slot for through-hole PCB installation.

Overview

The VISHAY 249 Series potentiometer is a single-gang, single-turn component with a cermet (ceramic-metal) resistive element. Its linear track taper makes it suitable for applications requiring voltage division or signal adjustment. Adjustment is made with a screwdriver slot, so a dedicated knob is not required.

Key Features

• Cermet resistive element for stability and durability
• Through-hole mounting for standard PCB (printed circuit board) installation
• 1 W power rating
• Linear taper with 100 kΩ ±10% track resistance
• Single-turn adjustment via screwdriver slot
• Temperature coefficient of ±100 ppm/°C
• Operating temperature range from -55 °C to +125 °C

Electrical Ratings

The component has a limiting element voltage of 300 V, a minimum insulation resistance of 1000 MΩ at 500 VDC, and a minimum dielectric strength of 750 Vrms. It is rated IP50, providing basic protection against dust ingress.

Dimensions and Weight

Dimensions are 3.3 (width) x 1.5 (depth) x 4.3 (height), with a weight of 5 g.

Applications

Designed for prototyping, industrial controls, and audio equipment, this potentiometer suits designers and engineers who need a variable resistor with a defined specification for voltage division or signal adjustment.

Choose the VISHAY 249 Series 100 kΩ potentiometer when a through-hole, single-turn cermet variable resistor is required for a PCB design.
