M16878/5 (also known as MIL-W-16878/5, NEMA HP-3 Type EE) is a heavy-wall extruded PTFE insulated wire designed for high-temperature, high-voltage applications. Compliant with U.S. standard NEMA HP-3 TYPE EE, this wire is rated for 1000V AC and has a long-term operating temperature range of -60℃ to +200℃. Engineered to meet stringent mili tary and industrial standards, this wire delivers exceptional performance in environments where reliability, durability, and resistance to extreme conditions are critical.

• High Voltage & Temperature Rating: Operates reliably at 1000V AC, with continuous use from -60°C to +200°C .It can withstand short-term exposure up to 300°C, making it ideal for systems exposed to current overloads or mechanical stress.
• Heavy-Wall FEP Insulation: Minimum 0.015" (0.38mm) thick PTFE insulation for enhanced dielectric strength and voltage withstand.
• Superior Chemical & Environmental Resistance: Inert to most chemicals, non-flammable, self-extinguishing, and stable against UV, oxidation, and moisture.
• Low Dielectric Loss: PTFE's low dielectric constant minimizes power loss and signal degradation, making it suitable for high-frequency and precision electronic applications.

• Aerospace & Defense: Internal avionics wiring, missile guidance systems, and mili tary electronic

• Industrial Controls: High-temperature processing equipment, furnace controls, and sensor wiring

• Instrumentation: Panel and meter internal wiring where dimensional stability is critical

• High-Frequency Applications: Low power loss characteristics make it ideal for RF and high-speed signal transmission

• Medical Electronics: Equipment requiring sterilization or exposure to chemicals

• Downhole Drilling: High-temperature oil and gas exploration equipment

MIL-W-16878/5 MIL Spec wire is intended for electrical or electronic use in protected applications where high temperature will be encountered. The MIL Spec wire has excellent resistance to thermal aging, solder iron damage, flame, and moisture. PTFE also resists solvents, greases, ozone and most other chemicals. These wires are easy to install due to their small size and slippery surface. PTFE has excellent, stable electrical characteristics with low power loss, making it ideal for high frequency applications.
