The silicone resin encapsulation used for the MF72 series offers high temperature resistance (above 300), fast heat dissipation, and good insulation. While the surface may appear rough and prone to minor friction marks, these do not affect product performance and can be manually erased. The material is firm but brittle; improper handling (e.g., heavy drops, bending leads) may cause minor cracks or chipping at the lead pins. These cosmetic imperfections have been tested and proven not to impact the product's performance or reliability.
