3、 Key recommendations for selection
1. Current and heat dissipation
For applications exceeding 30A, alloy/metal plate jumpers (such as LRZ or JR series) should be selected, as ordinary thick films are prone to overheating and failure;   
Power derating requirement: When the ambient temperature is greater than 70 ℃, the current should decrease by 10%/℃.
