Lab Series Thermal Straps

Lab Series are the most economical foil-type thermal straps available. Terminal geometry options are limited in the Lab Series because they are made using pre-fabricated components. They are made from the same top quality materials used in our other thermal straps. Just choose a shape and provide dimensions. Lab Series straps come with block terminals. Screw holes can be requested in any pattern.

General guidance is offered at no charge. Should you need it, Thermotive offers thermal analysis, design, and testing services.

* The heat path length is measured in milimeters -- mid-terminal to mid-terminal. If the heat path measures 100 mm, then x=100.

How to Order:

First review the thermal strap shape drawings shown below. If the thermal link desired is similar to one of those shown, then:

    1. Select the model required using the table above to select the foil width.
      Example: LAB-725
    2. Click on and review the L, S, and U-shape drawings (PDF). Select the desired strap shape by adding the letter to the part number.
      Example: LAB-725-S
    3. Add the thickness, terminal types, and characteristic dimensions (A, B, C) highlighted in the drawing to the finished part number.
      Example: LAB-725-S-200-BT-BH-1.250-2.450
    4. Contact us with your desired part numbers. If applicable, also include a simple sketch with hole sizes and placement. Our technical staff will contact you promptly with a quote, and lead time.
      The part number will follow this format:

For modified versions of the Lab Series designs you can either send us a dimensioned hand sketch or modify one of the shape drawings (PDF). Just send us a picture or scan with the modifications or your unique shape. Simple variations will be priced as standard Lab Series thermal links.
