PRG18BC150MM1RB電路保護的PTC可復位保險絲規(guī)格書PDF中文資料

PRG18BC150MM1RB屬于電路保護的PTC可復位保險絲。由村田制作所制造生產(chǎn)的PRG18BC150MM1RBPTC 可復位保險絲PTC 可復位保險絲可在電流超過一定限值時用于阻斷電流（過流保護）。保險絲的工作原理是：其溫度會因電流增大而升高，導致電阻變大。跳閘電流為 14 mA 至 50 A，跳閘時間為 8 ms 至 90 s。PTC = 正溫度系數(shù)。

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)
