The 3296Z-1-253LF is a 3/8" square Trimpot® trimming potentiometer manufactured by Bourns, featuring a 25 kO nominal resistance value with multiturn cermet construction for industrial sealed applications. This device offers infinite resolution with exceptional adjustability of ±0.01% voltage and ±0.05% resistance, along with a contact resistance variation of 1.0% or 3 ohms maximum. The potentiometer operates over a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, and is rated for 0.5 watts at 70°C. The unit features a chevron seal design, 25 turns nominal effective travel, and is RoHS compliant with 100% tin-plated terminations (LF designation). Common applications include precision instrumentation, signal conditioning, and industrial control systems where fine-tuning and long-term stability are essential.
