SMD Economy Trimmers Type 3204 Series Type 3204 Series Characteristics Electrical Resistance Range: 100R to 1M Standard Resistance Values: 1, 2, 5 in each decade Resistance Tolerance: 25% Temperature Coefficient of Resistance: 250ppm / C ( -30C to 100C) Resistance Law: Linear Maximum Operating Voltage: 50V DC or AC RMS maximum Resolution: Essentially Infinite Contact Resistance: <10R below 1K - <1% above 1K The 3204 miniature chip trimmer Power Rating: 0.1W at 70C incorporates the latest technology Effective Electrical Angle: 250 20 developments and has been rigorously tested to the highest standards. Special attention during the design of the product, ensures that this component meets specific requirements of hybrids and modern surface mounting boards. It is fully sealed until you are ready to trim, so it is highly suitable for Characteristics Mechanical Rotational Torque: 2 to 20 mNm Mechanical Adjustment: 240 Weight: 0.11 grams Soldering Strength: Horizontal 500gf minimum Vertical 500gf minimum both dip and wave soldering. It can then be resealed by the use of rubber based lock paint. Characteristics Environmental Key Features Temperature Range: - 20C to 85C Temperature Storage: 500 hours at 70C Suitable for Dip and Wave Soldering Rotational Life: 20 cycles Load Life: R < 5% after 1000 hours Available in Standard 12mm Tape Sealing: Sealed for 20 operations Soldering Heat: 250C 5C for 5 1 seconds Available from Stock Humidity Load Life: R 5% after 500 hours at 95 RH under load Small, Compact Size (4mm Square) High Temperature Rise: R 5% after 500 hours at 100C Terminal Layout Stops Solder Bridging Smooth Top Assists Placement Cermet Element Derating Curve 100 Rated Power (%) 80 60 40 20 0 0 10 20 30 40 50 60 70 80 90 100 Ambient Temperature (C) When the ambient temperature exceeds 70C, reduce the rated power and current in accordance with the derating curve given Literature No. 1773132 Issued: 03-08 Dimensions are shown for reference purposes only.

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 the potentiometer.
