Unique-Bargains Slow Blow Micro Fuse T3.15A 250V 10Pcs Black

SKU CH-2QST-8JD7C

Pack of ten slow-blow micro fuses rated 250V T3.15A with 8mm x 7.5mm bodies and 22mm pins

  • Time-delay protection prevents nuisance trips with T3.15A 250V rating
  • Ten-piece pack supplies multiple replacements for service work
  • Compact 8mm x 7.5mm x 4.2mm body fits tight PCB layouts
  • 22mm pins suit standard through-hole soldering
  • 5mm pin spacing matches common DIP footprints

T3.15A 250V Micro Fuses for PCB Protection

These 10-pack slow-blow micro fuses protect printed circuit boards from sustained overcurrent. The T3.15A 250V rating suits low-voltage power supplies and control circuits. Hobbyists and repair technicians use them for board-level fault isolation.

DIP Mounted Body with 4.5mm Pin Spacing

Each fuse measures 8mm x 7.5mm x 4.2mm with a 22mm pin length for through-hole soldering. The 4.5mm pin distance matches standard DIP footprints. Black thermoplastic body withstands normal soldering heat without deformation.

Verify Your Board Layout Before Ordering

Confirm the existing fuse footprint matches the 4.5mm pin pitch and 8mm body length. Check that the circuit requires a time-delay characteristic rather than fast-acting protection. Ensure the 250V rating exceeds your application's maximum operating voltage.

Questions about this item

What current and voltage does the T3.15A 250V rating allow on a PCB?

The fuse is rated for 3.15 amps at 250 volts. Its slow-blow design tolerates brief inrush currents above 3.15A without opening, while sustained overloads will melt the element.

Will the 8mm x 7.5mm body and 4.5mm pin spacing fit my board layout?

The square body measures 8mm long, 7.5mm wide and 4.2mm high. Pins are 22mm long on a 4.5mm pitch, so verify your footprint matches those dimensions before soldering.

How do I solder these DIP micro fuses without damaging the time-delay element?

Use a temperature-controlled iron at the lowest effective heat. Apply the tip to each pin for under three seconds; excessive dwell time can shift the slow-blow calibration inside the black body.
