1. Introduction: The High-Stakes World of High-Power Electronics

High-power electronics in automotive (e.g., EV drivetrains) and aerospace (e.g., electric aircraft systems) operate under extreme conditions: up to 800V in EV batteries, 50,000g shock in aerospace components, and -196°C to 300°C thermal cycles. Traditional tapes like Brown circuit board high temperature tape often fail to meet these demands, leading to costly failures. Gold Finger Electronics Polyimide Tape Kapton offers a game-changing solution, combining electrical insulation, mechanical robustness, and thermal stability.

2. Key Performance Metrics for High-Power Applications

2.1 Electrical Insulation

2.2 Mechanical Durability

3. Target Industries: Automotive Engineering
