Thermal Pad Types & Applications in Electronics
Communica stocks thermal pads designed for:
- Power electronics: Ensuring safe heat dissipation from MOSFETs, regulators, diodes.
- PC/laptop upgrades: Cooling for CPUs, GPUs, VRAM modules, SSDs, and chipset surfaces.
- LED lighting: Maintaining low junction temps in COB/MCPCB light fixtures.
- Automotive & industrial: Power inverters, motor drivers, and battery pack thermal management.
- Repair/replacement: Swapping old or degraded pads in production or maintenance.
Main Specification Parameters
| Spec | Typical Range | Notes |
|---|---|---|
| Thermal Conductivity (W/mK) | 1 - 12+ | Higher = better heat transfer. Select for high-power circuits. |
| Thickness | 0.5 mm - 5 mm+ | Choose to bridge gaps between surfaces/heatsinks. |
| Hardness/Compressibility | Soft, medium, firm | Softer pads conform to uneven surfaces for better contact. |
| Operating Temp ( degreesC) | -40 to +200 (typical) | Check datasheet for extreme/high-power requirements. |
| Electrical Insulation | Yes/No | Use insulating pads under live metal parts (e.g., TO-220 MOSFETs). |
Depending on your application, you might prioritise high conductivity for power electronics, or extra thickness for bridging larger gaps on PCBs or heatsinks. Our technical staff can help cross-reference datasheets for pad upgrades and compatible accessories.

Selection Guide: How to Choose the Right Thermal Pad
- Size: Measure the footprint of your component or mounting spot. Cuttable pads are available for custom sizing.
- Thickness: Select a thickness that gently compresses under mounting pressure without bowing or excessive squish-out. For CPU/VRAM gaps, slightly thicker pads (1-2 mm) are common.
- Conductivity: For power electronics (e.g., MOSFETs, LEDs), aim for >=3 W/mK. For general IC cooling, 1-3 W/mK usually suffices.
- Electrical Properties: If a pad will contact exposed metal, ensure it is rated as an electrical insulator.
- Brand/Material: Match to application needs-silicone for versatility/ease, graphite for higher performance, or specialty offerings for unique cases.
Always check the product datasheet for mechanical and operating limits, especially in environments with fluctuating temperature or vibration. If you need a comparison, Communica staff can suggest alternate brands or pad variants from local stock.
Practical Example - PC GPU Upgrade
A Cape Town PC technician needs to refurbish the thermal interface on an older graphics card. They measure the RAM module pads at 1.5 mm thick, select pads rated 6 W/mK for improved cooling, and use scissors to cut the chosen sheet to size. Collection is arranged from the Cape Town branch. Total parts cost: approx. ZAR 50-120 per card, depending on pad area and material (estimate as of 2024).
Tip: For industrial power installs, always clean surfaces and handle pads with gloves to avoid introducing oils or debris that reduce thermal efficiency.
