PTGL09AS1R2K2B51A0电路保护的PTC可复位保险丝规格书PDF中文资料

PTGL09AS1R2K2B51A0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PTGL09AS1R2K2B51A0PTC 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. 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.
