TC33X-2-104E is a 3 mm surface-mount trimming potentiometer (Trimpot) manufactured by Bourns, designed for precision resistance adjustment in compact electronic applications. This model features a 100 kO standard resistance value with ±25% tolerance, rotational stop design (TC33X-2 variant), and an adjustment angle of 270° ± 20°. The device operates over a temperature range of -40°C to +100°C with a temperature coefficient of ±250 ppm/°C, and is rated for 0.15 watts at 70°C with a maximum power rating of 50 VDC. The potentiometer exhibits essentially infinite resolution, contact resistance variation of 5% maximum, and is RoHS compliant with reflow soldering compatibility. It is commonly used in instrumentation, signal conditioning, and calibration circuits where precise trimming and compact form factor are essential.
