MIL-W-16878/24 NEMA HP-3 Type E Nickel Plated Copper 250V Tape-Wrapped PTFE Wire

Product Overview

MIL-W-16878/24 is a 250V thin-wall wire built to NEMA HP-3 Type E specification. It pairs a nickel-plated copper conductor with tape-wrapped PTFE insulation, delivering continuous operation up to 260°C — well above the 200°C limit of silver-plated PTFE types. The film-wrapped construction flexes more easily than extruded alternatives, survives vibration better, and resists insulation shrinkage, all in a compact thin-wall profile that saves space and weight.

Together, the nickel-plated copper conductor and sintered PTFE tape provide excellent dielectric strength, chemical inertness, and solder-iron resistance — making MIL-W-16878/24 a practical choice for compact, high-reliability internal wiring in demanding environments.

Key Features

*260°C continuous rating — Nickel-plated copper conductor enables operation well above the 200°C limit of silver-plated PTFE wires.

*Tape-wrapped flexibility — Film-wrapped PTFE bends more readily and recovers better than extruded insulation, easing routing in dense harnesses.

*250V in thin-wall form — NEMA HP-3 Type E construction maintains dielectric integrity while keeping outer diameter minimal.

*Solder heat immunity — PTFE insulation won't melt, drip, or shrink when exposed to soldering temperatures.

*Chemical and moisture proof — PTFE remains inert against solvents, oils, acids, humidity, and ozone exposure.

*Lightweight, space-saving profile — Thin-wall tape-wrapped build reduces bulk in weight-sensitive assemblies.

Typical Applications

* High-Temperature Electronic Assemblies
Power modules, heating elements, and proximity sensors that run hot benefit from the 260°C nickel-plated conductor in MIL-W-16878/24. The tape-wrapped PTFE insulation endures thermal cycling without cracking or delaminating.
* Compact Aerospace Wiring
When conduit space is at a premium, the thin-wall diameter of M16878/24 fits more conductors into tighter spaces. The tape-wrapped construction also survives repeated flexing better than extruded types, reducing in-field failures.
* Industrial Instrumentation Near Heat Sources
Control systems mounted adjacent to furnaces, ovens, or exhaust systems need wiring that resists thermal aging. NEMA HP-3 Type E construction handles the heat while the nickel plating maintains conductivity at elevated temperatures.
* Test Fixtures and Engineering Prototypes
Evaluation rigs and prototype gear undergo repeated thermal and mechanical stress. The combination of nickel-plated copper and tape-wrapped PTFE in MIL-W-16878/24 tolerates both without premature aging.
* Harsh-Environment Sensor Connections
Chemical processing, oil & gas, and automotive powertrain zones expose wiring to fuels, solvents, and extreme heat. M16878/24's PTFE insulation and nickel conductor resist degradation where conventional materials break down.

Frequently Asked Questions (FAQ)

Q: What is MIL-W-16878/24 wire used for?A: MIL-W-16878/24 is a 250V, thin-wall cable with nickel-plated copper conductor and tape-wrapped PTFE insulation, equivalent to NEMA HP-3 Type E. It is used in high-temperature, space-constrained wiring applications across aerospace, industrial, and defense sectors.

Q: Is M16878/24 the same as MIL-W-16878/24?A: Yes. M16878/24 is the abbreviated form of MIL-W-16878/24.

Q: Can M16878/24 replace M16878/23?A: They share the same nickel-plated copper conductor and 260°C rating. The difference is insulation method:M16878/24 is tape-wrapped (more flexible), while M16878/23 is extruded (more uniform wall). Choose based on your flexibility vs. wall consistency needs.Q: What does NEMA HP-3 Type E mean?A: Type E is the NEMA HP-3 classification for PTFE-insulated equipment wire with tape-wrapped (film-wrapped) construction. It defines the insulation build, voltage class, and temperature rating.Q: Can M16878/24 be soldered?A: Yes. The sintered PTFE tape-wrapped insulation withstands soldering iron temperatures without melting, shrinking, or deforming, ensuring clean and reliable terminations.Q: Is M16878/24 suitable for aerospace applications?A: Yes. As a mil-spec wire, MIL-W-16878/24 is widely specified in aerospace and avionics systems where high temperature, light weight, and reliable flexing are mission-critical.Q: What is the dielectric test voltage for M16878/24?A: Per the MIL-W-16878 specification, the AC RMS dielectric test voltage for 250V-rated wire is typically 1500V for 1 minute. Verify exact test requirements against your project specifications.
