8 / 12 page SPECIFICATION No. JVR03Z-7148B 8/12 UNCONTROLLED COPY REFERENCE ONLY 7.5 Operating environmental conditions The trimmer potentiometer should not be used under the following environmental conditions. If you use the trimmer potentiometer in an environment other than listed below, please consult with a Murata factory representative prior to using. (1) Corrosive gaseous atmosphere. ( e,g. Cl ,H S,NH ,SO ,NO etc) (2) In liquid. ( Ex. Water, Oil, Medical liquid, Organic solvent, etc) (3) Dusty/dirty atmosphere. (4) Direct sunlight. (5) No static voltage or electric/magnetic fields. (6) Direct sea breeze. (7) Other variations of the above. 7.6 Storage Conditions (1) To ensure the solderability of the terminal, store that the temperature is -10 to +40°C and the relative humidity is 30 to 85% RH, and use within six months after delivery. If you are going to use a product that has been stored for more than six months, please check its solderability beforehand. (2) Do not store in or near corrosive gases. (3) Do not store under direct sunlight. 7.7 Circuit design guide (1) Please confirm specifications of required trimmer potentiometers (power rating, maximum operating voltage, operating temperature, etc.). (2) When using with partial load (rheostat), minimize the power depending on the resistance value. (3) If the trimmer potentiometer is used in DC and high humidity conditions, please connect wiper (#2) for plus and resistive element (#1 or #3) for minus. (4) Use trimmer potentiometer within 90% of the effective-electrical rotational angle to prevent a sudden change of resistance when excessive current is applied. (5) The maximum input voltage to a trimmer potentiometer should not exceed (P R)^ 1/2 or the maximum operating voltage, whichever is smaller. (6) If the mounting process includes reflow soldering for the upper side of the PCB and flow soldering for its lower side and a product is mounted on the upper side by reflow soldering without cleaning, take the following cautions in order to prevent the flux from flowing onto the wiper sliding surface. 1. Don't place the product within 10 mm from the outer edge of the PCB. 2. Don't provide a through hole near the product. (A distance of 10 mm or more between the product and a through hole is necessary.) 8. Notice (1)Please make sure that your product has been evaluated in view of your specifications with our product being mounted to your product. (2) You are requested not to use our product deviating from the agreed specifications. (3) Please return one duplicate of this product specification to us with your receipt signature. If the duplicate is not returned, this product specification will be deemed to have been received by you. (4) We consider it is not appropriate to include any terms and conditions with regard to the business transaction in the product specifications, drawings or other technical documents. Therefor, if your technical documents as above include such terms and conditions such as warranty clause, product liability clause, or intellectual property infringement liability clause, they will be deemed to be invalid. *P: Power rating (W) R: Normal resistance value (ohm) - + #1 #2 #3 |
