1Shockproof, moisture resistant, heat resistant and good heat dissipation 2Completely insulated for printed circuit boards 3On the porcelain rod, the wire is wound and then the joint is welded, which can produce accurate resistance value and prolong life. 4The high resistance value is made of metal oxide film body (MO) instead of winding method, and the performance is stable. 5Excellent heat resistance, small temperature coefficient of resistance.
