Marking

Marking uses 2 characters. The first digit shows significant figures, and the second digit shows the quantity of zeros that follow. For E series, significant digits are represented by alphabets (e.g., 1.5 = E, 2.2 = J).

Application Notes

  • Adjustment force should be less than 4.9N (500gf).
  • Avoid excessive force on the sliding part during adjustment to prevent deformation or damage.
  • Insert adjustment driver perpendicular to the sliding part.
  • Reflow soldering is recommended; flow soldering is not suitable.
  • Be cautious of flux and solder scattering during soldering.
  • This product is not washable.
  • Handle with care.
  • Adhesives for fixing the slider are not recommended due to potential contact instability.
  • Excessive soldering time or temperature can impair product functions.
  • For reflow soldering, cream solder thickness should be 100-150 m.
  • Ensure proper insulation measures if wiring patterns are present directly beneath the product after mounting.
  • Refer to EIAJ RCR-2191A for potentiometer usage guidelines.

Safety Considerations

For applications requiring high safety and reliability, implement fail-safe designs such as protective circuits or redundant circuits to mitigate risks associated with component failures.

Product Storage Conditions

  • Recommended: Normal temperature (5 to 35 ), normal humidity (45% to 85% RH).
  • Storage period: 6 months from delivery.
  • Store in original packaging without applying stress.
  • Avoid direct sunlight and corrosive gas atmospheres.
