Jumper Wires

Jumper wires are used primarily for routing, bypassing, and/or connecting circuits. They are also called jumper cables, jumper cords, jumper leads, and jump leads, depending on the configuration of the wire.

Jumper wires look like insulated cables with one end of the wire pinched off (the crimped end). The other end of the wire is typically left open to accommodate a connector. The connector can be either soldered or pressed into place. These wires are often used to bridge two components on a printed circuit board (PCB) and are usually colored to distinguish them from the other components.

Pre-Crimped Leads

Pre-crimped leads are components that come pre-wired and pre-crimped. This makes them ready for direct insertion into a circuit board. Pre-crimped leads are often used in place of jumper wires because they are typically stronger and less prone to breakage. They also make it easier for the operator to connect small components together.

The leads are usually made from conductive wires that are pre-crimped and pre-secured with insulation. This makes them more durable than most jumper wires because the metal conductor won’t become loose or damaged when inserting or removing it from the circuit board.

0430300002-03-A4-D Application Field and Working Principle

The 0430300002-03-A4-D is an example of a pre-crimped lead. It is a two-pin male to female lead that can be used to connect components together on a printed circuit board or as a jumper wire. The pins are crimped to ensure a secure connection. It can also be soldered to the board if needed.

The 0430300002-03-A4-D is typically used in automotive, industrial, and medical applications due to its ability to withstand extreme temperatures and electrical vibrations. Its working principle is relatively straightforward; the pins are engaged when connected, allowing current to pass through the wire.
