30-piece slow-blow micro fuse kit
This pack contains thirty DIP-mounted miniature square fuses rated at 250V and T1A. They are intended for circuit protection on printed circuit boards in consumer electronics, instrumentation and low-power supplies. Hobbyists and repair technicians who need a ready stock of through-hole replacements will find the quantity convenient.
Through-hole mounting with 4.5mm pin spacing
Each fuse has a body measuring 8.5mm by 7.5mm by 4mm and pins 20mm long spaced 4.5mm apart, matching standard 0.18-inch pitch footprints. The leads are long enough to reach through typical board thicknesses and can be trimmed after soldering. Installers should verify the exact hole pattern before committing to a layout, as slight variations in legacy boards can misalign the pins.
Time-delay protection for 1A circuits
The slow-blow characteristic tolerates brief inrush currents while still interrupting sustained overloads at 1A, making them suitable for transformer primaries, small motor drivers and capacitive inputs. They are not suited to fast-acting requirements or circuits that exceed the 250V rating, and the 1A limit means they cannot protect higher-current rails without additional coordination.

Questions about this item
How do I confirm the slow-blow T1A 250V fuse is working after soldering it to the PCB?
Apply rated current and verify the circuit remains powered; the time-delay element should hold through brief surges without opening, then measure continuity across the 4.5 mm spaced pins to confirm a closed circuit.
The pack lists 30 pieces — are any holders, sockets or tools included or must they be purchased separately?
Only the 30 micro fuses are supplied; DIP sockets, PCB holders or soldering equipment are not included and must be sourced separately.
Which variant should I choose if my board requires an 8.5 mm x 7.5 mm body with 20 mm pins?
This single variant matches those dimensions exactly — 8.5 mm length, 7.5 mm width, 4 mm height and 20 mm pin length — so no other version selection is needed.
