Product details

12 GHz Bandwidth and 500-Cycle Mating Life

The 031-70530: Rated to 12 GHz maximum frequency, this jack supports the full bandwidth of 3G-SDI and 12G-SDI video signals with margin. The 75-Ohm impedance is held through the PTFE dielectric and the precision centre-contact geometry — a 50-Ohm BNC would introduce a reflection at the transition. The 500-cycle mating life is typical for a bayonet-lock BNC with gold-plated centre contact; the bayonet coupling provides quick connect/disconnect without the thread wear of an SMA, and the gold plating keeps the contact resistance stable across those cycles.

Frequently asked questions

Is 031-70530 a 75 ohm BNC connector?

Buyers need to confirm impedance match for their RF system to avoid signal reflection.

What is the difference between 031-70530 and 031-70230?

Often confused with 50 ohm version, so this comparison prevents wrong part selection.

Where can I buy 031-70530 with immediate stock?

Sourcing buyers need to fill BOM line quickly and want to know available distributors.

What is the mounting type and finish of 031-70530?

Design engineers need to verify through hole compatibility and nickel finish for corrosion resistance.

Is there a replacement for 031-70530 if it goes obsolete?

Brokers and long-term buyers need cross references for lifecycle planning.

How many mating cycles does the 031-70530 BNC jack support?

Maintenance techs and reliability engineers evaluate longevity for repeated connections.
