10-Pack DIP Micro Fuses T3.15A 250V
These ten slow-blow micro fuses are rated 250V and 3.15A for DIP mounting on circuit boards. They suit repair technicians and hobbyists protecting low-power electronics such as power supplies, chargers or small appliances. Each fuse has a black cylindrical body measuring 8.3mm by 7.7mm with 20mm pins spaced 4.5mm apart. The pack provides convenient spares for bench stock or field service kits.
Slow-Blow Time-Delay Protection
The slow-acting blow characteristic tolerates brief inrush currents without nuisance tripping, making these fuses suitable for circuits with capacitive or inductive loads. They interrupt sustained overloads at 3.15A while surviving momentary surges above that level. The 250V rating defines the maximum circuit voltage the fuse can safely clear. No higher voltage or current rating is implied by the time-delay design.
Verify Board Layout Before Ordering
Check that your PCB footprint matches the 8.3mm diameter, 7.7mm thickness, 20mm pin length and 4.5mm pin spacing before ordering. Ensure the circuit voltage does not exceed 250V and the normal operating current stays below 3.15A. These fuses are not intended for primary mains protection in high-energy installations or for applications requiring fast-acting interruption.

Questions about this item
How do I know whether the T3.15A 250V rating is the one I need for my board?
Match the fuse to the circuit's maximum continuous current and voltage; the T3.15A 250V marking means it will hold 3.15 amps indefinitely and interrupt safely at up to 250 volts.
What does the "T3.15A" marking actually tell me about how the fuse behaves once it is soldered in?
The "T" prefix identifies a slow-blow element, so brief inrush currents above 3.15A are tolerated while a sustained overload will open the fuse to protect the circuit.
The pins are spaced 4.5mm apart — will that fit a standard DIP footprint on my PCB?
Yes, the 4.5mm pin pitch and 20mm pin length are designed for through-hole DIP mounting on a matching 4.5mm grid.
