Anti-Surge Resistor

Design & Construction

These components utilize cylindrical ceramic cores with specialized glazed coatings for enhanced thermal stability. The structural design provides 20-30% greater surface area compared to flat chip resistors, enabling efficient heat dissipation during high-energy pulse events. Advanced flame-retardant materials equivalent to UL94 V-0 standards ensure operational safety in demanding environments.
