The PVG3A501C01R00 is a single-turn, surface-mount cermet trimmer potentiometer from the PVG3 series. It provides a total resistance of 500 ohms with a ±20% tolerance and has a power rating of 0.25W at 70°C. This component features a mechanical rotation of 250° and an effective electrical rotation of 210°, with a temperature coefficient of resistance (TCR) of ±150 ppm/°C. Housed in a sealed 3mm square J-hook package and rated for an operating temperature range of -55°C to +125°C, it is ideal for precise calibration in compact electronic circuits.
