9 / 44 page 7 1 !Note • Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc. • This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please approve our product specifications or transact the approval sheet for product specifications before ordering. s Notice (Soldering and Mounting) s Notice (Handling) s Notice (Other) Before using trimmer capacitor, please test after assembly in your particular mass production system. 1. Soldering (1) TZR1 series can be soldered by reflow soldering method and soldering iron. Do not use flow soldering method (dipping). (2) Soldering condition Refer to the temperature profile. If the soldering conditions are not suitable, e.g., excessive time and/or excessive temperature, the trimmer capacitor may deviate from the specified characteristics. (3) The amount of solder is critical. (4) The thickness of solder paste should be printed from 100 micro m to 150 micro m and the dimension of land pattern should be Murata's standard land pattern used at reflow soldering. Insufficient amounts of solder can lead to insufficient soldering strength on PCB. Excessive amounts of solder may cause bridging between the terminals or contact failure due to flux wicking up. (5) When using soldering iron, the diameter of the string solder should be less than 0.5mm. The string solder should be applied to the lower part of the terminal only. Do not apply flux except to the terminals. Excessive amounts of solder and/or applying solder to the upper part of the terminal may cause fixed metal rotor or contact failure due to flux invasion into the movable part and/or the contact point. The soldering iron should not come in contact with the monolithic stator of the trimmer capacitor. If such contact does occur, the trimmer capacitor may be damaged. (6) Our recommended chlorine content of solder is as follows. (a) Solder paste: 0.2wt% max. (b) String solder: 0.5wt% max. (7) Do not use water-soluble flux (for water cleaning). To prevent the deterioration of trimmer capacitor characteristics, apply flux only to terminals. 2. Mounting (1) Do not apply excessive force (preferably 5.0 N [Ref: 500gf] max.), when the trimmer capacitor is mounted on the PCB. (2) Do not warp and/or bend PCB to prevent trimmer capacitor from breaking. (3) Use the suitable dimension of the pick-up nozzle (1.1-1.2mm external diameter and 0.8-0.9mm bore diameter). 3. Cleaning Cannot be cleaned because of open construction. 4. Other Note the polarity of the trimmer capacitor to minimize influence by stray capacitance. (Refer to the dimensions concerning the polarity.) 1. Use suitable screwdrivers that fit comfortably in driver slot. *Recommended screwdriver for manual adjustment MURATA: KMDR160 2. When adjusting with a screwdriver, do not apply excessive force (preferably 0.5 N [Ref: 50gf] max.) to minimize capacitance drift. If excessive force is applied to the screwdriver slot, it may cause deformation of the products. 3. Do not apply adhesive, lock paints, or any other substances to the trimmer capacitor to secure the rotor position. They may cause corrosion or electrical contact problems. • This PDF catalog is downloaded from the website of Murata Manufacturing co., ltd.
