6-Pin Jumper on 2.54 mm Grid — What It Bridges
The 69145-206LF: It mates with matching square-pin headers to selectively short adjacent pins — common for configuration jumpers, address bits, or enable lines on a PCB. In a production test fixture or a field-configurable board that gets re-jumpered quarterly, that plating grade keeps the connection reliable past the product's service life. This is a signal-level jumper — use it for logic-level power, pull-up/down networks, or low-current sensor paths, not for bus bars or motor feeds.
Open-Top Profile — Why It Matters on the Board
The open-top design means the top of the shunt is exposed — no cover, no closed lid. That gives you probe access from above with a multimeter tip or a scope probe while the shunt is installed, which is handy during board bring-up or field troubleshooting. The trade-off is that the contacts are exposed to incidental debris; in a clean, enclosed assembly this is rarely an issue. Mated stack height is 0.200" (5.08 mm) above the header base — a low profile that keeps the jumper clear of adjacent components in a dense layout. The black polyester housing (UL94 V-0) resists flame propagation inside the equipment enclosure.
