PVM4 Series Notice ■ Notice (Operating and Storage Conditions) 1. Store that the temperature is -10 to +40deg. C and the relative humidity is 30-85%RH. 2. Do not store in or near corrosive gases. 3. Use within six months after delivery. 4. Open the package just before using. 5. Do not store under direct sunlight. 6. The trimmer potentiometer should not be used under the following environmental conditions: If you use the trimmer potentiometer in an environment other these listed below, please consult with Murata factory representative prior to using. (1) Corrosive gaseous atmosphere. (Ex. Chlorine gas, Hydrogen sulfide gas, Ammonia gas, Sulfuric acid gas, Nitric oxie gas, etc.) (2) In liquid. (Ex. Oil, Medical liquid, Organic solvent, etc.) (3) Dusty/dirty atmosphere. (4) Direct sunlight. (5) Static voltage nor electric/magnetic fields. (6) Direct sea breeze. (7) Other variations of the above. ■ Notice (Rating) 1. When using with partial load (rheostat), minimize the power depend on the resistance value. 2. The maximum input voltage to a trimmer potentiometer should not exceed (P•R)^1/2 or the maximum operating voltage, whichever is smaller. 3. The maximum input current to a trimmer potentiometer should not exceed (P/R)^1/2 or the allowable wiper current, whichever is smaller. 5 ■ Notice (Soldering and Mounting) 1. Soldering (1) Can be soldered by reflow soldering method, flow soldering method, and soldering iron. (Incase of flow soldering, it is necessary to clean after soldering.) (2) Use our standard land dimension. Excessive land area causes displacement due to effect of the surface tension of the solder. Insufficient land area leads to insufficient soldering strength of the chip. (3) Standard soldering condition (a) Reflow and flow soldering : Refer to the standard temperature profile. (b) Soldering iron: >Temperature of tip 260deg.C max. >Soldering time 3sec. max. >Diameter 2mm dia. max. >Wattage of iron 30W max. Before using other soldering conditions than those listed above, please consult with Murata factory representative prior to using. If the soldering conditions are not suitable, e. g., excessive time and/or excessive temperature, the trimmer potentiometer may deviate from the specified characteristics. (4) Apply the appropriate amount of solder paste. The thickness of solder paste should be printed from 100micro m to 150micro m and the dimension of land pattern should be used Murata's standard land pattern at reflow soldering. Insufficient amounts of solder can lead to insufficient soldering strength on PCB. Excessive amounts of solder may cause the bridging between the terminals. (5) The soldering iron should not come in contact with the case of the trimmer potentiometer. If such contact does occur, the trimmer potentiometer may be damaged. 2. Mounting (1) Do not apply excessive force (preferable 9.8N (Ref.; 1kgf) max.), when the trimmer potentiometer is mounted to the PCB. (2) Do not warp and/or bend PC board to prevent trimmer potentiometer from breakage. (3) In chip placers, the recommended size of the cylindrical pick-up nozzle should be outer dimension 4.0mm dia. and inner dimension 2.0mm dia.. 3. Cleaning (1) Isopropyl alcohol and Ethyl alcohol are available material for cleaning. For other materials, please consult with Murata factory representative prior to using. (2) The total cleaning time by cold dipping method shall be less than 5 minutes. The total cleaning time by hot dipping method shall be less than 2 minutes. The total cleaning time by ultrasonic washing (conditions as below) method shall be less than 1 minutes.

PVM4 Series Notice Continued from the preceding page. In case of the mixed conditions with hot dipping and ultrasonic washing, the cleaning time by hot dipping shall be less than 1 minutes and the cleaning time by ultrasonic washing shall be less than 1 minutes. In case of the mixed conditions with hot dipping, ultrasonic washing and vaper, the cleaning time by hot dipping shall be less than 1 minutes, the cleaning time by ultrasonic washing shall be less than 30 seconds and the cleaning time by vaper shall be less than 30 seconds. If the trimmer potentiometer is cleaned by ■ Flow Soldering Standard Profile other conditions,the sealing construction may be damaged. Due to the ultra-sonic cleaning equipment peculiar self resonance point and the cleaning compatibility usually depends on the jig construction and/or the cleaning condition such as the depth of immersion, please check the cleaning equipment to determine the suitable conditions.

Murata connot guarantee trimmer potentiometer integrity when used under conditions other than those specified in this document. 32 applied, the trimmer potentiometer may not function. 3. Please use within the effective rotational angle. The potentiometer dose not have a mechanical stop for over rotation. In case out of effective rotational angle, the trimmer potentiometer may not function. 4. When using a lock paint to fix slot position, please use adhesive resin without chlorine or sulfur (Three-bond "1401series").
