PTFE insulated silver plated copper winding wire is used in applications where high thermal, chemical, electrical or mechanical security is required.
The main advantages are the very low HF resistance by the “Silver plated” core and the relatively thin shielding for optimal contact with the ring core, yet an insulation value of 600 Volts.
PTFE is highly resistant to oils, lubricants, fuels and is not combustible, while it is still very flexible.
Ideal for a high degree of reliability, such as your BalUn!
Diameter: 22 AWG
Core: 19 x 0.15 mm copper “Silver plated”
The wire is thin enough to make a good balun on a FT-140-43 toroid.
