Description
This M3x6 red fiber washer is specially designed for electrical insulation and mounting of TO-220 and TO-3P package transistors onto metal heat sinks. Made from high-temperature-resistant fiber material, it sits between the screw and the component tab, preventing electrical contact and ensuring long-term reliability in high-power circuits.
The washer is lightweight, reusable, and compatible with mica insulators, making it a key part of safe heat sink mounting in amplifier boards, SMPS units, and power regulators.
🔧 Key Features:
- Size: M3 inner diameter × 6mm outer diameter
- Material: High-quality red fiber
- Purpose: Electrical insulation and vibration damping
- Compatible with M3 screws, mica sheets, and TO-220/TO-3P components
- Heat resistant and non-conductive
- Prevents short circuits between screw head and transistor tab
- Reusable and durable
📦 Applications:
- Mounting TO-220 regulators (7805, LM317, LM338)
- Power transistors (TIP122, IRF540, BD139, 2SC5200, 2SA1943)
- Audio amplifiers, SMPS, LED drivers
- Inverter and motor control circuits
- Use with mica insulators and thermal paste in power electronics
