1. Soldering
  (1) TZ03 series can be soldered by flow soldering 
       method and soldering iron.  Do not use reflow 
       soldering method.
  (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 dimension of mounting hole should be Murata's 
       standard mounting hole used at flow soldering. 
       The amount of solder is critical. 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.
  (4) When using soldering iron, the string solder 
       shall 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 rotor or the 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 plastic
       case of the trimmer capacitor. If such contact 
       does occur, the trimmer capacitor may be damaged.
  (5) Our recommended chlorine content of string 
       solder is 0.5wt% max.
  (6) 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) Use the suitable PCB holes which are the same 
       pitch as the terminal of the trimmer capacitor.
       If it would not fit with the terminal, the 
       excessive stress would be applied to the 
       terminal and the trimmer capacitor may deviate 
       from the specified characteristics.
  (3) Do not apply bending stress more than 10.0N 
       (Ref: 1kgf) after the trimmer capacitor has 
       been mounted on the PCB.
  (4) Mount trimmer capacitor in contact with PCB.
  (5) In case of bending the terminals, do not apply 
       excessive force to the body of the product and 
       prevent the terminal fixing part from damaging.
3. Cleaning
    Isopropyl alcohol and Ethyl alcohol are available 
    material for cleaning. If you use any other types
    of solvents, please evaluate performance by 
    your set.  Moreover, please confirm no damage for 
    trimmer capacitor after cleaning by your conditions.
4. Other
    Note the polarity of the trimmer capacitor to 
    minimize influence by stray capacitance.
    (Refer to the dimensions concerning the polarity.)
