(a)  Category: Ceramic Trimmer Capacitor

 

(b)  Outer size : Plastic casing type :6mm

 

(c)  Maximum nominal capacitance : PF unit in 3 digits (The1st and 2nd figures

 

indicate the significant figures, but the 3rd indicates the number of naught.)

 

(D) Adjusting types : R (Reverse Type) or Blank (Normal Type)

 

3.Rated voltage : 100VDC

 

4.Temperature range : -25℃to +85℃

 

5.Test circumstance :Test should be done at 20℃ with relative humidity at 65%. However, subjected to special requirement,the ideal range should be within ±5℃ and humidity from 45℃to 85℃

 

6. Electrical Characteristic

 

6.1 Capacitance Drift After Adjustment

 

Rotation shall be made for 5 cycles for 180°at a rate of 20 r/mm, a capacitance value difference woul d be found immediately. Once the shaft is stopped at the position of the maximum capacit-ance value after 24 hours later. The specification range should be within 5pF, 10pF ± 1.5% and 30pF ± 2%.

 

6.2 Temperature Characteristics

 

When measured the capacitance at 1MHz±10%, it reached the heat balance at each temperature changed to

 

.+20℃to -25℃with adjusting to 80%~90% of the maximum capacitance, the capacitance change is based on the capacitance at +20℃ of 2nF, stage of changing the temperature as above.

 

6.3 Q (Quality factor)

 

When measured at 20℃, 0.5V to 5V, 1MHz and maximum capacitance ,the Q values are listed in the attached specification.

 

6.4 Insulation Resistance

 

When applied 100VDC between terminals for 1 minute at the maximum capacitance, the insulation resistance shall be more than 10,000M.

 

6.5 Withstanding Voltage

 

There is no abnormality after applied 220VDC (1ess than 5mA) for 5 seconds between the terminals.

 

7.  Structure and mechanical characteristics

 

7.1 Configuration and Dimensions

 

Please refer to the attached drawings.

 

7.2 Strength of Terminals

 

When applied a power to the terminals to any direction slowly and kept at 0.5 kg for 10 seconds, the terminals shall not be loosen or broken mechanically.

 

7.3 Torque

 

The torque test should be done at least for l round tuning from to for the Normal Type, or to for the Reverse Type . Please note that it might cause the torque will decrease against the rotation increase.

 

7.4 Solder ability

 

When dipped the terminals into the soldering pot at 255℃±5℃ for 2±0.5 seconds. There is almost 75% of the total dipped surface are covered with the new solder.( Caution: Keep the soldering conditions as above. If the soldering conditions are not suitable (excessive time, excessive temperature and etc.), it's performance will be seriously deviated.
