PVG3A200C01R00 is a sealed surface-mount trimmer potentiometer from Bourns designed for precision circuit adjustment and tuning applications. This single-turn device features a 20 ohm ± 20% total resistance value with a cermet element, housed in a compact 3 mm square SMD package with J-hook pin style. The potentiometer delivers 0.25 W power rating at 70 °C, supports an effective rotation angle of 210° ± 10° with a mechanical rotation angle of 250° ± 10°, and maintains a temperature coefficient of resistance (TCR) of ±150 ppm/°C across the operating range of -55°C to +125°C. The sealed metal cover provides thermal protection and heat transfer, while RoHS compliance ensures environmental compatibility. This component is ideal for applications requiring reliable, compact trimmer functionality in consumer electronics, industrial equipment, and telecommunications systems where space constraints and environmental sealing are critical.
