Applications
The Würth Elektronik 61302621121 is commonly used in embedded computing boards, Arduino-compatible shields, industrial I/O modules, and PLC expansion cards requiring a 26-pin, 2.54 mm dual-row male header. Its gold-plated contacts ensure reliable signal integrity across thousands of mating cycles in test fixtures and hot-swap backplane assemblies. The standard 0.100 inch pitch makes it interchangeable with widely available mating receptacles for modular prototyping and volume production.

Frequently Asked Questions
How many circuits does the Würth Elektronik 61302621121 support, and what is its contact pitch?
The 61302621121 supports 26 circuits arranged in a dual-row configuration with a 2.54 mm (0.100 inch) pitch per row, providing 13 pins per row. This standard pitch ensures compatibility with a wide range of mating sockets and receptacles used in Arduino shields, Raspberry Pi HATs, and industrial daughter-card designs.
What current rating does each contact in the 61302621121 support, and what does that enable?
Each contact in the 61302621121 is rated at 3A, allowing a 26-position connector to carry up to 78A in aggregate if all pins are used for power. In practical designs, this rating supports mixed-use configurations where several pins deliver 3.3V or 5V power rails alongside digital signal lines without overheating the gold-plated contacts.
Why is the gold-plated contact finish on the 61302621121 important for test and measurement equipment?
Gold plating provides contact resistance below 30 mΩ and resists oxidation over thousands of mating cycles, which is critical for test fixtures and laboratory instruments that require repeatable low-noise connections. For precision measurement boards using the 26-pin 2.54 mm header in signal chains operating below 1 mV, the gold finish prevents resistance drift that copper or tin contacts would exhibit after repeated insertions.
