Main features:
1. It has good direct solderability (self-soldering), and can be
soldered directly after winding, and has excellent and fast direct
solderability at 360°-400°. Eliminate the work of removing
insulating paint and improve labor efficiency.
2. In the high frequency state, it has good "Q" value
characteristics.
3. The paint film has excellent adhesion, which is convenient for
winding. After the coil is wound, the insulation of the paint film
remains good.
