Temperature label-
Supermini 1K

Color transition simulation

Very small indicator of 0.5cm2 with single indicator point. Best for small electric or electronic parts

Temperature range:40~125℃
RoHS Compliant
*For indoor use only

THERMO LABEL ® SUPER MINI 1K is single-use indicators irreversibly change its color from white to black by reaching or exceeding color changing temperature. The indicator element is only φ1.5mm and the label itself is a square 0.5cm on a side. Best suited for temperature control of electronic and electric parts like transistor, IC, capacitor and small motor.
Reversible Irreversible Semi-reversible


  • Extra small design for narrow space and small devices
  • 1 point temperature indication
  • Irreversible, single-use
  • Temperature range: 40℃ to 125℃
  • Self-adhesive and easy to apply on various location. (The back side is coated with heat resistant adhesive material)

Apply where temperature monitoring is required.

Usage consideration

  • Do not rub the color changing part. This may cause abnormal color change.
  • Apply on flat surface. THERMO LABEL® SUPER MINI 1K might drop from uneven applying surface.
  • Avoid applying on curved surface and bending indicators.
  • Do not cut THERMO LABEL®SUPER MINI 1K. This may reduce the durability of product and cause abnormal color change.

Effective lifetime

Indoor use: 3 years
Outdoor use:THERMO LABEL®SUPERMINI 1K is not designed for outdoor use



Store unused indicators under room temperature and dark condition Avoid high temperature and excessive humidity.



Color change

  • The color change temperature and its accuracy were determined in room temperature with 2-3℃/min of heating rate. Under special condition, color change temperature might be changed.
  • The performance of irreversible temperature labels which change color at 130℃ or higher may be changed if it is exposed to temperatures in the -10℃ from the specified temperature.

Applying label

  • Remove water, oil, rust and dust from the surface before applying labels. Contamination and uneven surfaces can cause labels to drop and abnormal color change.
  • Remove release film and apply where temperature monitoring is required and press the surface of label gently with finger or cloth. Strong rubbing might damage the label and affect performance (abnormal color change).
  • Apply labels on flat surface. Labels are not designed to apply on curved and corner surface.
  • Do not change shape of products. Cutting products with a cutter knife or re-shaping can reduce the durability and cause abnormal color change.


  • Do not use electromagnetic induction heating, for example, microwave oven, under high pressure condition and high vacuum condition.
  • THERMO LABEL®SUPERMINI 1K is not designed for outdoor use.
  • Do not use THERMO LABEL®SUPERMINI 1K under liquid (such as water, oil, grease, plasticizer* or solvent) affected condition. When THERMO LABEL®SUPERMINI 1K absorbs the liquid, indicator may change color and/or may impact adhesion of THERMO LABEL®SUPERMINI 1K.
    *Plasticizer may be contained in insulating coating of electrical cable, terminal cap and vinyl chloride resin.
