Glass Fuse 500mA – 250V (Size T5x20mm)

Description

A Glass Fuse 500mA – 250V (Size T5x20mm) is a type of fuse used for overcurrent protection in electrical circuits. Below is a typical datasheet-style overview of its specifications:

Glass Fuse 500mA – 250V (T5x20mm)

General Description:

A 500mA fuse designed to provide protection for circuits by interrupting the flow of current when it exceeds 500mA (0.5A), at a maximum voltage of 250V. This fuse comes in a T5x20mm size, which is a common size used in low-voltage electronic circuits for general-purpose protection.

Key Specifications:

Electrical Characteristics:

Time-Current Characteristics (Slow Blow):

• This fuse has a slow-blow (time-delay) characteristic, meaning it can tolerate short surges or spikes in current before blowing, making it suitable for circuits with inrush currents like motors, capacitors, or transformers.
  • 500mA Fuse Time-Delay: The fuse will withstand short-term overloads but will open the circuit if the current exceeds the rated value for a prolonged period. The fuse is typically designed to open between 1.5 and 3 times the rated current.

Mechanical Characteristics:

• Body Material: Glass (for easy visibility of any potential internal damage or discoloration).
• Size: T5x20mm
  • T5: 5mm in diameter
  • 20mm: Length of the fuse body
• Terminal Type: Axial (leads on both ends for easy soldering onto the PCB).
• Mounting Type: Through-hole (standard for glass fuses).

Applications:

• Overcurrent Protection: For general-purpose overcurrent protection in circuits up to 250V.
• Power Supplies: Protects low-power circuits such as power supply inputs, LED circuits, and small appliances.
• Consumer Electronics: Protection in devices like chargers, small home appliances, and audio equipment.
• Automotive: Used for in-car circuit protection where the circuit operates at 12V or 24V, and a small current fuse is needed for protection.
