PTGL09AS3R3K4B51B0電路保護的PTC可復位保險絲規(guī)格書PDF中文資料

PTGL09AS3R3K4B51B0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PTGL09AS3R3K4B51B0PTC 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. Small fluctuation in the circuit due to resistance tolerance +/-10

2. Narrow current range (less than twice) between operating and

non-operating current at -10 to 60 degrees C.

3. Quick operating time due to small size compared with

conventional products.

4. Best suited to meet the requirements for power supplies and

motor protection. Error-free operations are assured by rush current.

5. Circuit is protected until current is turned off.

6. Restores the original low resistance value automatically once

the overload is removed.

7. Non-contact design leads to long life and no noise.

Durable and strong against mechanical vibration and shock

because it is a solid element.
