Datasheet
|||||| |---|---|---|---|---| |||||| |||||| ||Thermalsil™ III|||| ||RoHS Compliant|||| ||<br>**Thermally Conductive Silicone Rubber Insulators**|||| ||<br>The newest Thermalsil™ III formula has improved thermal conductivity,|||| ||<br>providing excellent thermal resistance. It is used as an electrically-isolating|||| ||<br>interface material composed of silicone elastomer binder with a thermally|||| ||<br>conductive filler. It is reinforced with glass cloth to resist tearing and cut-|||| ||<br>through due to burns on transistors or heat sinks.|||| ||Thermalsil™ III eliminates the need for grease application and conforms to|||| ||<br>mounting surfaces under clamping pressure for optimum heat conduction.|||| ||Thermalsil™ III is .152mm (.006") thick and grey green in color. A finely|||| ||<br>woven glass cloth provides the thinnest possible matrix for enhanced thermal|||| ||<br>resistance.|||| ||To order Thermalsil™ III with adhesive coated backing, add suffix "AC" to the|||| ||<br>part number. For example, 53-03-2AC.|||| ||Thermalsil™ III is available in any configuration with adhesive backing. Order|||| ||<br>by adding "AC" after the part number. For example: 53-03-2AC.|||| ||Bulk Thermalsil™ III|||| ||Thermalsil™ III is also available in three widths, with and without adhesive|||| ||coated backing (AC). Thermalsil™III is .152mm (.006") thick.|||| |||||| |||||| |||||| ||**Thermalsil™ III**|||| |||||| ||**Property**|**Typical Value 25°C**|**Test Method**|| ||**Electrical**|||| ||Dielectric Constant|2.5@50 Hz||| |||2.5@103Hz|ASTM D150|| |||2.5@106Hz||| ||Dielectric Breakdown<br>Voltage|26.3 x 103volts/mm (667||| ||||ASTM D149|| |||volts/mil)ASTM D-149||| |||||| ||Volume Resistivity|5.7 x 1015ohm-cm|ASTM D257|| ||Dielectric Dissipation<br>Factor|.008@50 Hz||| |||.004 @103Hz|ASTM D150|| |||.004 @106Hz||| |||||| |**Physical**|**Physical**|**Physical**|**Physical**|**Physical**|**Physical**|**Physical**|**Physical**|**Physical**| |---|---|---|---|---|---|---|---|---| |Thickness<br>~~|~~||.15 + .03/-.05mm<br>(.006 + .001/-.002 in.)||||||| |Color<br>~~oo~~||Gray-Green||||||| |Tensile Strength<br>~~ee~~||6.1 x 107Pa(8786psil)||||||| |Hardness,Shore A<br>~~—~~||87||||||| |Elongation<br>~~ee~~||2% or less||||||| |**Thermal**||||||||| |Thermal Conductivity<br>~~—~~||0.92 w/m °C||||||| |Flame Resistance<br>~~|~~<br>~~-———_~~||UL 94V-0<br>~~-———_~~||||UL card #E-<br>58126(S)||| |Service Temperature<br>~~-———_~~||-60°C to 180°C<br>(-76°F to 356°F)<br>~~-———_~~||||||| |**Standard Thermalsil Configurations**<br>~~-———_~~||||||||| |10-218,<br>4<br>©||||||||| |**Part**<br>**Number**<br>~~a~~|**A**<br>~~a~~|**B**|**C**|**D**|**E**||**F**|**G**| |**53-02-**<br>**103***<br>~~a~~|23.80<br>(.937)<br>~~a~~|19.05<br>(.750)|16.66<br>(.656)|7.14<br>(.281)|9.53<br>(.375)|||3.18<br>(.125)| |* Theseinsulatorsmay also be usedfor TO-3PandTO-247devices.<br>~~a a~~||||||||| * These insulators may also be used for TO-3P and TO-247 devices.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
