The silicone resin encapsulation provides high temperature resistance (up to 300C), fast heat dissipation, and good insulation. While the silicone surface may show friction marks due to product handling (which do not affect performance and can be wiped off), and the material is firm but brittle, leading to potential minor cracks/chipping at the leads under improper force (which also do not affect performance or reliability), customers can use the product with confidence as these characteristics do not impact performance.
