Standard Series Thermal Straps

Standard Series thermal links come with specially machined strap terminals which can include mounting flanges and screw holes. These features give the engineer various mounting options which can be especially useful in compact instruments and test assemblies. The thickness or conductance is specified by the end user.

Some of the terminals and thermal strap shapes offered in the Standard Series are shown below. Other similar variations will be considered on an individual basis. Detail dimensions for the strap shape, terminal, and holes are made to specification (MTS). See the How to Order section below.

Thermoelectric cooler (TEC) selection and epoxy mounting options are also offered.

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:

Select the model required using the chart above to select the foil width.
Example: STA-725

    1. Click on and review the L, S, and U-shape drawings (PDFs). Select the desired strap shape by adding the letter to the part number.
      Example: STA-725-S
    2. If you already know the thickness you need, include it -- otherwise write 0 for now.
    3. Chose the terminal types for each end, with left terminal listed first. Select from Parallel Flange (PF), Orthogonal Flange (OF), Block Terminal (BT), Block Terminal with Holes (BH), or a unique Modified terminal (M). Add the thickness and terminal letters to the part number.
      Example: STA-725-S-0-PF-OF
    4. Add the characteristic dimensions (A, B, C) highlighted in the drawing to the finished part number.
      Example: STA-725-S-0-PF-OF-1.250-2.450
    5. Contact us with your desired part numbers.

      If the thickness isn't specified provide the operating environment (air / vacuum / other), nominal and worst case temperatures for each terminal, as well as the nominal and worst case heat load. You can also specify a minimum conductance. Thermotive will recommend a thermal strap thickness.

      If applicable, also include a simple sketch with hole sizes and placement. Thermotive will contact you promptly with a quote and lead time.

      The part number will follow this format:

For modified versions of the Standard 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 Series thermal links.
