盛雷城精密電阻有限公司生產制造的RJM73U0204和 RJM74U0207系列超晶圓電阻器具有超高穩定性和可靠性，是VISHAY公司 UMA0204 和 UMB0207系列的完全替代產品。

Ultra-pcision melf type resistors series RJM73U0204 and RJM74U0207 are of ultra high stability and reliability. They are the right cross to Vishay's UMA0204 and UMB0207.

Melf type wire wound fusible resistors are the new resistors made by Thunder Precision Resistor Co.in 2013.

Melf type wire wound fusible resistorsare used to as safetyprotection components with small size and high power capability and adjustable fusing power rating and fusible time duration.

線繞熔斷電阻器是近些年來研發出來的新型熔斷電阻器，晶圓型熔斷電阻器也就是MELF 型線繞熔斷電阻器是盛雷城精密電阻有限公司近年來退出的新型產品，產品具有體積小，功率密度高，熔斷功率和熔斷時間可以根據用戶的實際實際需要進行調整，所以具有無可替代的優越性。
