盛雷城精密电阻有限公司生产制造的RJM73U0204和 RJM74U0207系列超晶圆电阻器具有超高稳定性和可靠性，是VISHAY公司 UMA0204 和 UMB0207系列的完全替代产品。
Ultra-precision 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.
线绕熔断电阻器是近些年来研发出来的新型熔断电阻器，晶圆型熔断电阻器也就是MELF 型线绕熔断电阻器是盛雷城精密电阻有限公司近年来退出的新型产品，产品具有体积小，功率密度高，熔断功率和熔断时间可以根据用户的实际实际需要进行调整，所以具有无可替代的优越性。
