MIL-W-81822/4 wire—PTFE/polyimide insulation

MIL-W-81822/4

wires have thin wall extruded PTFE

insulation with a polyimide top coat for increased

cut-through and abrasion resistance.

All have solid conductors for wire-wrap applications

such as backpanel wiring, with a choice of three

conductor materials.

Performance:

Voltage rating:

300V.

Temperature rating:

-55 to 200˚ C.

Construction Details

Insulation:

Thin-wall extruded PTFE with polyimide

top coat.

Conductor:

Type A: Silver-plated ETP copper;

Type B: Silver-plated OFHC copper;

Type C: Silver-plated high strength

copper alloy.

Colors:

Color coded to MIL-STD-104.
