Mica Insulator for 2SC5200 & 2SA1943 Transistors – TO-3P High-Temperature Heat Sink Isolation Sheet

Description

This Mica Insulator Sheet (HEAT SINK MICA FOR 2SC5200, 2SA1943) is designed for TO-3P package transistors like 2SC5200 and 2SA1943, commonly used in high-power audio amplifier circuits and industrial power applications. The mica provides excellent electrical insulation between the transistor and the metal heat sink, while still allowing efficient heat transfer when paired with thermal paste.
Crafted from high-grade natural mica, this insulator is heat-resistant up to 500°C, thin yet durable, and easy to install. It protects your components from short circuits while ensuring they stay cool under load.

🔧 Key Features:
Compatible with 2SC5200, 2SA1943, and all standard TO-3P package transistors
Condition: New
Made from natural mica – excellent insulator and heat conductor
Withstands high temperatures up to 500°C
Thin and durable (approx. 0.1mm)
Prevents short circuit between transistor back and heat sink
Supports efficient cooling when used with thermal compound

📦 Applications:
Audio power amplifiers using 2SC5200 / 2SA1943
TO-3P transistor mounting in Class AB amplifier circuits
High-wattage speaker drivers and amplifier boards
Industrial power supplies and inverter systems
Heat sink mounting in SMPS and motor drivers
Any high-current, heat-sensitive transistor circuit

🧊 Note:
Always use with thermal paste or heat sink compound for best results in both thermal performance and electrical safety.

🧊 Note:
Product colour may vary slightly depending on batch and availability. Functionality remains the same. (Refer to the product image for illustration only. For exact specifications, please check the datasheet.)
