TR250-180U Information

Description

The TR250-180U is a resettable fuse, specifically a PPTC (Positive Temperature Coefficient) device. This model can handle up to 18A of current at a maximum voltage of 100Vdc and 250Vrms. It comes in a radial, disc package and is designed for applications where overcurrent protection with self-reset capability is required.

Features

The TR250-180U is a resettable fuse, specifically a PPTC (Polymorphic Plastic Thermocouple) type. Key features include:

Safety Reset
: The fuse resets automatically once the current flow exceeds the rated limit.
Limited Thermal Impact
: PPTCs have a lower thermal impact compared to conventional fuses, which reduces potential fire hazards.
Wide Voltage Range
: The TR250-180U can handle voltages up to 250Vrms and 100Vdc max.

In summary, the TR250-180U is a resettable fuse with safety features, thermal efficiency, and a wide operating voltage range.

Package

The package type for TR250-180U is radial, disc shape.

Manufacturer

The manufacturer of the TR250-180U is TE Connectivity. TE Connectivity is a global technology and manufacturing company, specializing in connectivity solutions, electronic components, and industrial equipment.
