PVG5/PV01 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. ■ Notice (Soldering and Mounting) 1. Soldering (1) Standard soldering condition (a) Reflow and flow soldering : Refer to the standard temperature profile. (b) Soldering iron : >Temperature of tip 260 deg.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 capacitor may deviate from the specified characteristics. (2) Can not be soldered using the flow soldering method. If you use the flow soldering method, the trimmer potentiometer may not function. (3) 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. (4) Insufficient amounts of solder can lead to insufficient soldering strength on PCB. Excessive amounts of solder may cause the bridging between the terminals. 2. Mounting (1) 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. (2) Do not apply excessive force (preferable 9.8N (Ref.; 1kgf) max.), when the trimmer potentiometer is mounted to the PCB. (3) Do not warp and/or bend PC board to prevent trimmer potentiometer from breakage. (4) 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 applicable solvent for cleaning. If you use any other types of solvents, please consult with Murata factory representative prior to using. (2) The total cleaning time by cold dipping, vaper and ultrasonic washing (conditions as below) method shall be less than 3 minutes. (3) For ultra-sonic cleaning, the available condition is as follows. >Power : 600W (67liter) max. >Frequency : 28kHz >Temperature : Ambient temperature 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 6 Continued on the following page. 37 catalog to prevent smoking and/or burning, Pleaseread readrating ratingand and!CAUTION !CAUTION(for (forstorage storageand andoperating, operating,rating, rating,soldering solderingand andmounting, mounting,handling) handling)ininthis thisPDF catalog to prevent smoking and/or burning, etc. etc. !Note •Please R50E12.pdf 02.9.5 you are requested approvespecifications. our product specification or to transact theour approval for product specificaion before ordering. •This Thiscatalog cataloghas hasonly onlytypical typicalspecifications. specificationsTherefore, because there is no space fortodetailed Therefore, please approve productsheet specification or transact the approval sheet for product specification before ordering.

The trimmer potentiometer shall be removed from the chamber, and maintained at a temperature of 25±5°C for 5±1/6 hours 1)PV-- series Full rated continuous working voltage not exceeding the maximum rated voltage shall be applied with the circuit shown in the figure. The adjustment rotor (screw) shall be continuously cycled through not less than 90% of effective-electrical rotational angle (number of turns), at the rate of 1 cycle for 5 seconds minimum to 2.5 a minutes maximum for total of 200 cycles. End Terminal Resistor 1 End Terminal 14 End Terminal Resistor 2 End Terminal Rotational Life DC supply Figure-4 2) PVG3, PVG5series The adjustment rotor (screw) shall be continuously cycled though not less than 90% of effective- electrical rotational angle (number of turns), at the rate of 1 cycle for 5 seconds minimum to 2.5 minutes maximum for a total of 50 (100 for PVG5) cycles, without loading. 3) PVF2, PVM4A---B01series The wiper shall be rotated over 90% of the effective rotational angle without loading at a speed of 10 cycles per minute, for 100 cycles continuously. 9 74
