Product Overview
MIL-W-22759/19 is a 600V ETFE lightweight wire featuring a high strength silver-coated copper alloy conductor. Rated for -55°C to +150°C, this Mil-Spec wire uses a thin extruded ETFE insulation to reduce overall diameter and harness weight without compromising dielectric strength.
The high strength silver-coated copper alloy conductor offers superior tensile strength and vibration resistance compared to standard copper, making it ideal for weight-critical aerospace, missile, and compact instrumentation wiring.
Key Features
Light-weight ETFE insulation — thinner extruded build reduces wire diameter and bundle mass compared to standard-wall ETFE constructions
High strength silver-coated copper alloy conductor — alloy substrate delivers better tensile strength and vibration resistance; silver coating ensures conductivity and corrosion protection
600V, -55°C to +150°C — ETFE chemistry maintains dielectric integrity and flexibility across extreme temperature swings
Broad AWG coverage — 26 AWG to 20 AWG in one specification, covering signal leads through power distribution feeds
Fluoropolyper resilience — resistant to aviation fluids, hydraulic fluids, solvents, ozone, and UV without cracking or softening

Typical Applications
Aerospace & Spacecraft: Reduces harness weight for satellites and avionics.
Missile & UAV Systems: Withstands high vibration and fits in tight airframes.
Mili-tary Vehicles: Resists fuels and chemicals in crowded electronics bays.
Test Equipment: Flexible and durable for repeated routing in test rigs.
Design & Installation Notes
Bend radius — the light-weight ETFE build allows tighter bends than heavy-wall alternatives; follow manufacturer recommendations to avoid insulation damage
Termination — silver-coated conductors accept standard soldering and crimping; ETFE insulation is solder-iron resistant
Color coding — available in standard colors (black, brown, red, orange, yellow, green, blue, violet, gray, white); custom colors on request
Storage — cool, dry environment away from direct UV; ETFE is highly stable but prolonged sun exposure should be avoided
Frequently Asked Questions (FAQ)
Q: What does "light-weight" mean for ETFE insulation?A: "Light-weight" refers to a thinner insulation build compared to standard-wall ETFE constructions. This reduces overall cable diameter and weight while maintaining the same 600V dielectric rating and 150°C temperature capability. The trade-off is slightly reduced mechanical protection — acceptable in applications where routing space and mass are more critical than abrasion resistance.Q: Can M22759/19 be used in space applications?A: Yes. ETFE insulation has excellent outgassing characteristics, and the high strength silver-coated copper alloy conductor meets the mechanical and electrical requirements of spacecraft wiring. Confirm specific qualification requirements (radiation tolerance, vacuum compatibility) with your application engineer.Q: Can I solder terminations directly to M22759/19?A: Yes. The extruded ETFE insulation withstands standard soldering iron temperatures without melting or shrinking, and the silver-coated conductor provides reliable solderability for clean, durable terminations.Q: Is M22759/19 RoHS compliant?A: RoHS-compliant options are available. Please confirm your requirement when requesting a quote.
