Product Description
3M Polyimide Film Electrical Tape 1205 is an amber, 0.081 mm polyimide tape with a non-corrosive acrylic pressure-sensitive adhesive for electrical insulation and solder masking. Its 0.025 mm film backing provides a thin insulating construction for coils, capacitors, transformers, wire harnesses, lead anchoring, and printed circuit board assembly. The tape is designed for continuous operation not exceeding 155 deg C under its UL listing. ASTM D1000 values include minimum dielectric breakdown of 6000 V, minimum insulation resistance of 1 x 10^12 ohm, and minimum elongation of 50%, with properties measured at 23 deg C unless otherwise stated.
Key features
- 155 deg C operation: The tape is designed for continuous operation not exceeding 155 deg C under its UL listing.
- 6000 V dielectric minimum: ASTM D1000 dielectric breakdown is at least 6000 V at 23 deg C.
- Pressure-sensitive installation: The acrylic adhesive requires no heat, moisture, or solvent preparation for application.
Applications
Applications include wrapping coils, capacitors, transformers, and wire harnesses; anchoring leads; and solder masking during printed circuit board assembly.
