Additional Details

The TMC2KJ series uses a carbon composition resistive element, with a resistance value of 680 Ohms. Expect tolerance to be typically around ±30%. Power rating will commonly be around 0.1 to 0.25 Watts. This is designed for through-hole mounting on PCBs. The trimmers typically allow for single-turn adjustments. The operating temperature range is commonly between -10°C and +70°C. The 'TR' suffix denotes tape and reel packaging, optimized for automated assembly. Expect Rotational life to be rated for hundreds of cycles.
