The TC42X-2-503E is a single-turn, open-frame cermet trimming potentiometer featuring a cross slot rotor for adjustment. This component provides a resistance of 50 kOhms with a standard tolerance of ±25% and has a power rating of 0.1 watts at 70°C. It is designed to operate reliably across a temperature range of -40°C to +100°C with a temperature coefficient of ±250 ppm/°C. Its compact 2 mm size, which meets the EIA/EIAJ standard trimmer footprint, makes it ideal for various surface-mount trimmer applications requiring precise circuit calibration.
