AHA Insulation Paper Polyimide Film with Aramide paper Class H
AHA Insulation Paper (Polyimide Film & Aramid Paper Composite) – Class H 180°C
Product Overview
Our AHA Insulation paper is a high-performance, three-layer flexible composite material. It is engineered by bonding Polyimide film (Kapton equivalent) with Aramid paper (Nomex type) on both sides using high-temperature resistant adhesive.
This material is specifically designed for high-end electronic components that demand extreme thermal stability and superior dielectric properties, such as the TDK ALT Series (ALT3232, ALT4532) inductors and high-frequency transformers.
Key Features & Benefits
-
Superior Thermal Resistance (Class H): With a continuous operating temperature of 180°C, this material provides a robust safety margin for power electronics and automotive-grade components.
-
Excellent Dielectric Strength: The central Polyimide film core ensures high voltage insulation even in ultra-thin profiles, allowing for the miniaturization of components like SMD inductors.
-
Mechanical Toughness: The outer Aramid paper layers provide excellent tear resistance and surface friction, making it ideal for high-speed automated winding processes.
-
Chemical & Solvent Resistance: Stable performance against common impregnating varnishes and cleaning solvents used in electronics manufacturing.
-
Optimized for TDK ALT Series: Perfectly suited for the insulation of TDK ALT3232 and ALT4532 series, ensuring reliable performance in LAN transformers and RF balun coils.
