Notes for piher potentiometer 10k

1. Most of the resistors of piher potentiometer 10k are made of polycarbonate synthetic resins. They should avoid contact with ammonia, other amines, alkali aqueous solutions, aromatic hydrocarbons, ketones, lipids, strong chemicals (high acid-base value), etc. Otherwise, their properties will be affected.           

 2. The terminal of potentiometer should avoid using water-capacitive flux when welding, otherwise it will promote metal oxidation and material mildew; avoid using inferior flux, poor soldering may cause tin difficulty, lead to poor contact or circuit break.            

3. If the welding temperature is too high or the welding time is too long, the terminal of piher potentiometer 10k may cause damage to the potentiometer. Welding of pin-type terminals should be completed in 235 +5 C within 3 seconds. Welding should be over 1.5MM of the potentiometer body. No solder should be used to flow through the circuit board during welding. Welding of wire-type terminals should be completed in 350 +10 C within 3 seconds. And the terminal should avoid heavy pressure, otherwise it is easy to cause bad contact.           

 4. When the Pich potentiometer is welded at 10K, the height of rosin (flux) entering the printing press plate should be adjusted properly. The flux should be avoided from intruding into the potentiometer. Otherwise, it will lead to bad contact between brush and resistor, INT and noise.            

5. The 10K of Pich potentiometer is best used in voltage adjustment structure, and the connection mode should be "1" foot grounding; the current adjustment structure should be avoided, because the contact resistance between resistance and contact plate is not conducive to the passage of large current.            

6. The surface of Pich potentiometer at 10K should avoid condensation or water droplets and use in wet places to prevent insulation deterioration or short circuit.            

7. When installing the "rotary" potentiometer to fix the nut, the strength should not be too tight to avoid destroying the screw teeth or poor rotation; when installing the "iron shell direct sliding" potentiometer, avoid using too long screw, otherwise it may hinder the movement of the sliding handle, or even directly damage the potentiometer itself.            

8. In the process of putting knob on potentiometer sleeve, the thrust force used should not be too large (not exceeding the parameters of the pulling force of the axis in the Specification), otherwise it may cause damage to potentiometer.            

9. The rotary operating force (rotation or sliding) of potentiometer will become lighter with the increase of temperature and tighter with the decrease of temperature. If the potentiometer is used in low temperature environment, it should be explained in order to use special low temperature resistant grease.The shorter the shaft or sliding handle of 

10. potentiometer, the better. The shorter the length of the shaft or sliding handle, the better and more stable the hand feel. On the contrary, the longer the shaking, the greater the change of hand feel.The power of carbon film of 

11. potentiometer can withstand the ambient temperature of 70 (?) C, and it may lose its function when the temperature is higher than 70
