30R800规格书详情
Radial Leaded PTC Resettable PTCs
• The 30R Series Resettable devices utilize a unique polymer-based, Positive Temperature Coefficient (PTC) material to protect electrical circuits against overcurrent conditions.
• In normal operation, the 30R Series PTC has many conductive paths and a very low resistance. In an overcurrent condition, the temperature of the polymer material rises. This dramatically reduces the conductive paths resulting in an immediate rise in resistance. In this condition, the device provides circuit protection by significantly limiting the flow of current. However, once the cause of the initial overcurrent condition is eliminated, the 30R Series PTC cools down and resets to a low resistance value permitting the normal current flow to resume.
• The 30R Series is a 30V Radial Leaded Device with a 40A Short Circuit Rating.
30R800属于电路保护 > PTC 可复位保险丝。力特公司制造生产的30R800PTC 可复位保险丝PTC 可复位保险丝可在电流超过一定限值时用于阻断电流(过流保护)。保险丝的工作原理是:其温度会因电流增大而升高,导致电阻变大。跳闸电流为 14 mA 至 50 A,跳闸时间为 8 ms 至 90 s。PTC = 正温度系数。
