PTGL09BD2R2N2B51B0電路保護的PTC可復(fù)位保險絲規(guī)格書PDF中文資料

PTGL09BD2R2N2B51B0屬于電路保護的PTC可復(fù)位保險絲。由村田制作所制造生產(chǎn)的PTGL09BD2R2N2B51B0PTC 可復(fù)位保險絲PTC 可復(fù)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(dǎo)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. Best suited to meet the requirements of the short-circuit test.

Quick response compared with current fuse and resistor and errorfree

operation are assured.

2. Small size save board space. Capable of being mounted

anywhere because Alternative is not required.

3. Actuates by excessive current during the short-circuit test to

restrain abnormal heat generation in other circuit components and

printed boards.

This state will be maintained until the abnormal state is removed

or power is turned off to reset the POSISTOR to the original state.

Surface temperature of POSISTOR is kept low, below a certain

value, during the actuation.

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

Durable and strong against mechanical vibration and shock

because it is a solid element.
