With rated voltage applied between terminals 1 and 3, the straight
line which connects the measured output values VB and VA at
specified reference positions B and A is assumed to be an ideal
straight line, so that deviation against the ideal straight line when
the voltage applied between terminals 1 and 3 is assumed to be
100％can be expressed as a percentage.

1. When using an infrared reflow oven, solder may not always be applied as intended. Be sure to use a hot air reflow
oven or a type that uses infrared rays in combination with hot air.
2. The temperatures given above are the maximum temperatures at the terminals of the potentiometer when
employing a hot air reflow method. The temperature of the PC board and the surface temperature of the
potentiometer may vary greatly depending on the PC board material, its size and thickness. Ensure that the surface
temperature of the potentiometer does not rise to 240˚C or greater.
3. Conditions vary to some extent depending on the type of reflow bath used. Be sure to give due consideration to this
prior to use.
Notes
2. Cleaning Cleaning should not be attempted.
3. Type of solder to be used Use cream solder that contains 10 - 15 %wt flux.
4. Number of solder applications - apply solder only once
Measurement and Test Methods
〔Total Resistance〕
The total resistance, with the shaft（lever）placed at the end of terminal 1 or 3, shall be determined by measuring the
resistance between the resistor terminals 1 and 3 unless otherwise specified.
〔Rating Voltage〕
The rating voltage corresponding to the rated power shall be determined by the following equation. When the resulting
rated voltage exceeds the maximum operating voltage of a specific resistor, the maximum operating voltage shall be
taken as the rated voltage.
