Product Overview
MIL-W-22759/20 is a 1000V PTFE high temperature wire with silver-plated copper alloy conductor, rated -55°C to +200°C. Defined in SAE AS22759/20, this high temperature wire uses extruded PTFE insulation — to deliver high thermal endurance and superior chemical resistance for demanding industrial and electronic applications.
M22759/20 pushes both envelopes: 1000V dielectric strength and 200°C continuous operation make it the go-to 1000V PTFE high temperature wire for ovens, drying chambers, motor compartments, and computer backplanes that run hot or carry higher voltages.
Built with a silver-plated copper alloy conductor for reliable conductivity and corrosion resistance, and available in fine gauges from 20 to 28 AWG, this wire bridges the gap between heavy-duty power wiring and precision signal routing — all in a single PTFE-insulated family.
PTFE Performance Profile
PTFE (polytetrafluoroethylene) brings a unique set of properties that make it the insulation material of choice for extreme environments:
200°C continuous rating — PTFE maintains its mechanical and insulating properties at temperatures, giving you real-world thermal margin
Near-zero outgassing — critical for cleanroom, aerospace, and sealed enclosure applications where volatile emissions from insulation can contaminate sensitive components
Universal chemical resistance — PTFE is inert to virtually all industrial chemicals, making it ideal for chemical processing, semiconductor fabrication, and pharmaceutical environments
Ultra-low dielectric constant and loss factor — excellent for high-frequency signal transmission where signal integrity matters
Non-flammable and smoke-free — PTFE does not support combustion and produces minimal smoke, supporting fire safety requirements in enclosed spaces

Where M22759/20 Fits Your Project
* Industrial Ovens & Drying Equipment -- The MIL-W-22759/20's PTFE insulation handles 200°C continuously, making it a natural fit for food processing ovens, paint curing chambers, and textile drying equipment.
* Computer & Electronic Backplane Wiring -- The 1000V rating and PTFE chemistry of MIL-W-22759/20 provide reliable performance in backplane interconnects, power distribution modules, and high-speed signal routing where both voltage headroom and thermal stability are critical.
* Motor & Generator Lead Wiring -- The silver-plated copper alloy conductor of this 1000V PTFE high temperature wire maintains low contact resistance and resists tarnish, while the PTFE insulation withstands thermal cycling without cracking or losing dielectric strength.
* Laboratory & Analytical Instrumentation -- PTFE's ultra-low outgassing and chemical inertness make MIL-W-22759/20 suitable for cleanroom-compatible instrumentation, mass spectrometers, and other sensitive equipment where insulation integrity directly affects measurement accuracy.
Frequently Asked Questions (FAQ)
Q: What AWG sizes are available for M22759/20?A:MIL-W-22759/20 is available in 20, 22, 24, 26, and 28 AWG. The 28 AWG size (7/36 stranding) offers a fine-gauge option for precision signal applications within this specification.
Q: How does PTFE insulation differ from ETFE in practical terms?A: PTFE offers a higher continuous temperature rating (200°C vs 150°C), lower outgassing, and slightly better chemical resistance. For applications operating below 150°C with modest voltage requirements, ETFE-based wires may be sufficient. For high-voltage or high-temperature environments, PTFE provides the necessary margin.
Q: Is M22759/20 suitable for cleanroom or aerospace use?A: Yes. PTFE's ultra-low outgassing characteristics make MIL-W-22759/20 suitable for cleanroom and space-qualified applications. Confirm specific qualification requirements with your application engineer.
Q: Can I solder terminations directly to M22759/20?A: Yes. The extruded PTFE insulation withstands standard soldering iron temperatures without melting or shrinking, and the silver-plated conductor provides reliable solderability for clean, durable terminations.
Q: Is M22759/20 RoHS compliant?A: RoHS-compliant options are available. Please confirm your requirement when requesting a quote.
