3103X102N

SMD Economy Trimmers Type 3103 Series Type 3103 Series Characteristics Electrical Resistance Range: 200R to 1M Resistance Values: 1, 2, 5 in each decade Resistance Tolerance: ± 30% Temperature Coefficient of Resistance: ± 500ppm / °C (25 to 85°C) ± 750ppm / °C (-25 to 25°C) Resistance Law: Linear Max. Operating Voltage: 50V dc Contact Resistance Variation: 5% of Nominal Max. The latest miniaturised sealed trimmer Power Rating: 0.05W at 50°C from Citec is the smallest, lightest Effective Electrical Angle: 260° ± 20° sealed potentiometer available and the most cost effective. Consuming just 10.5mm2 of board real estate, it has been developed specifically for new generation hand held equipment, where double sided component placement is often unavoidable. These 3mm devices are only 1.8mm high. Due to the innovative carbon on polymer tech- Characteristics Mechanical Rotational Torque: 1 to 15 mNm Adjustment (End Stop Torque): 20 mNm Weight: 0.09 grams Terminal Robustness: Horizontal 10 N Vertical 5 N nology, the device sets new standards in low cost high reliability electro mechanical components.

Anode Oxidation When D.C. current is used and the trimmer is to remain in one set position for a long period, it is good practice to connect the negative line to the resistance element and the positive line to the wiper terminal. With the polarity reversed, particularly in moist conditions, it is possible for surface oxidation of the contact to cause a resistance increase. Storage For maximum possible shelf life do not disturb polythene sleeve until you are ready to use.
