Frequently Asked Questions
What contact finish does the QTT-113-04-G-T use, and why does it matter for long-term reliability?
The QTT-113-04-G-T features gold (20 µin) over nickel contact finish on mating surfaces, which provides excellent corrosion resistance and ensures consistently low contact resistance over thousands of mating cycles. This makes it suitable for applications where reliable electrical performance must be maintained over the product lifetime.
How does the 2.00 mm pitch of the QTT-113-04-G-T compare to standard 2.54 mm pitch connectors in board-stacking designs?
At 2.00 mm pitch, the QTT-113-04-G-T is more compact than standard 2.54 mm pitch connectors, enabling 39 positions to fit in a body length of approximately 1.037 inches. This tighter pitch benefits space-constrained stacking designs in embedded computers and telecommunications equipment where PCB real estate is at a premium.
What is the contact material used in the QTT-113-04-G-T, and how does it affect spring performance?
The QTT-113-04-G-T uses phosphor bronze for its contact material, which offers a high modulus of elasticity and excellent spring-force retention. This ensures consistent normal force at the mating interface over repeated mating cycles and across operating temperatures ranging from -55°C to +125°C.
In which board-stacking applications is the QTT-113-04-G-T's power plane design most advantageous?
The power plane terminal strip design of the QTT-113-04-G-T is particularly advantageous in multi-board power distribution applications where multiple voltage rails must be routed across 39 pins at 2.00 mm pitch. This is common in industrial control backplanes, mezzanine computing cards, and modular communication chassis requiring high current capacity and stable board-to-board connections.
