## PTGL05AR181M7P52B0 

## Appearance & Shape 

## Features 

1. Best suited to meet the requirements for power supplies and motor protection. Error-free operations are assured by rush current. 2. Circuit is protected until current is turned off. 

3. Restores the original low resistance value automatically once the overload is removed. 

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. 

## Applications 

Limited Usage Consumer Grade 1. Transformers Other Usage 2. Transistors 3. Fluorescent Lamps 

## Packaging Information 

Minimum Packaging Specifications Order Quantity B0 Bulk(Bag) 500
