Mounting Kits

• Pre-packaged in heat-sealed plastic bags for use on assembly line.
• Stock mounting hardware using one number for better control and identification. Part number can be printed on the bag if requested.
• Standard kit contains Thermalfilm insulator. For high maximum operating temperatures (550°C), order a mica insulator by adding suffix letter "M" to the part number. For electrical isolation and excellent thermal resistance, use In-Sil-8 for an insulator by adding suffix letter "S' to the part number.
• Other insulator materials available include: hard anodized aluminum and aluminum oxide.
• Refer to proper product section for drawings of insulators and shoulder washers used in the mounting kits.
