PRG18BC2R2MM1RB电路保护的PTC可复位保险丝规格书PDF中文资料

PRG18BC2R2MM1RB属于电路保护的PTC可复位保险丝。由村田制作所制造生产的PRG18BC2R2MM1RBPTC 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。

1. Rapid operation to protect the circuit in an overcurrent condition

abnormality such as a short circuit.

By removing the overcurrent condition, these products

automatically return to the initial condition and can be used repeatedly.

2. Suitable for countermeasure to short circuit test in safety standard

3. Stable resistance after operation due to ceramic PTC

4. Similar size (0603 size) is possible due to the large capacity for electric power.

5. Possible to use these products as current limiting resistors with overcurrent protection functions

6. SMD type is helpful for miniaturizing circuits because of its small size and light weight

7. UL/cULcertified product.(UL1434, File No. E137188)
