Multicolored Dupont jumper wires kit 120 pieces 40 pin 20 cm length

EL-CP-004 Wire Cap Connectors 120pcs 40pin 20cm

SKU CH-GHRV-CKK0Q MPN EL-CP-004

Kit of 120 multicoloured Dupont jumper wires in male-to-female, male-to-male and female-to-female 40-pin strips, each 20 cm long

  • Product colorBlack
  • 120 jumper wires cover male-to-female, male-to-male and female-to-female needs
  • 20 cm length suits standard breadboard spacing
  • Cables separate cleanly for custom pin counts
  • Copper-clad aluminium conductors with PVC insulation
  • 40-pin strips support odd-spaced headers

120-piece jumper wire kit

This kit supplies 120 individual jumper wires in three 40-pin configurations: male-to-female, male-to-male and female-to-female. Each wire measures 20 cm in length and features a black PVC insulation over a copper-clad aluminium conductor. The cables can be separated to match non-standard header spacing. They are intended for low-voltage breadboard prototyping at 5 volts.

Suitable for Arduino and breadboard prototyping

Hobbyists, students and educators building temporary circuits on 40-pin headers will find the assortment convenient. The single-strand construction is not suited for high-current loads, frequent flexing or permanent installations requiring soldered or crimped connections. Builders needing shielded cables, higher voltage ratings or locking connectors should select a different product.

40-pin compatible 20 cm length

The 20 cm wire length determines reach between components on a standard breadboard or between a microcontroller board and external modules. Verify that this length fits your layout before purchasing.

Questions about this item

Will the 120 copper-clad aluminum jumper wires need replacement after repeated breadboard insertions?

The single-strand copper-clad aluminum conductors are rated for 5 volts and can be separated as needed; repeated insertion cycles may eventually fatigue the strands, so inspect for loose pins before each project.

What limits continuous use of the 40-pin male-to-female, male-to-male and female-to-female cables at 5 volts?

The 20 cm PVC-insulated wires carry low-voltage signals only; sustained current near the conductor’s ampacity will cause voltage drop and insulation warming before any connector failure occurs.

Do the 120-piece Dupont cables generate noticeable heat or noise when powering an Arduino project all day?

At 5 volts the copper-clad aluminum jumper wires produce negligible heat and no audible noise; the 0.06 lb kit stays cool during continuous low-current operation.
