Power Integrity Certified
Raising the Standard for Power Interconnects
When engineers talk about system performance, signal integrity usually gets the headlines. Without clean, reliable signals, nothing works as it should. But as we’ve seen before, behind every flawless waveform lies power integrity. It’s the quiet, dependable partner that keeps everything running smoothly. Without it, even the best signal paths can’t perform.
At Samtec, we’ve spent years helping designers understand and improve both sides of the equation. To demonstrate this, we use the Power Integrity Certified badge. This badge serves as a mark of assurance that a connector has been thoroughly tested, analyzed, and verified to deliver consistent power performance in real-world conditions.
What Power Integrity Really Means
Power Integrity (PI) is all about stability. In an ideal world, every circuit would receive a perfect, constant voltage and current. In practice, connectors, cables, and PCB traces introduce small but important variations. Voltage drop, resistance, and contact heating can all affect how much usable power reaches the load.
These variations may seem minor, but in modern high-density or high-speed systems, small changes can create big problems. A drop in supply voltage can distort signal timing or trigger errors in sensitive components. Even the cleanest signal can fail if the power feeding it isn’t stable. While Signal Integrity ensures data gets through clearly, power integrity ensures the hardware keeps the lights on.
Testing Power Integrity
To give engineers clearer insight into connector performance, Samtec provides standard Power Test Data for select power systems. This includes key parameters:
- Current carrying capacity
- Working voltage
- Voltage drop and resistance
- Creepage and clearance
However, testing is just part of the story. Real systems do not operate in perfect laboratory conditions. They experience load changes, temperature cycles, and long hours of operation. To reflect that, Samtec performs the Current Cycling Test (EIA-365-55) on select products. This test repeatedly drives current through the connector under varying conditions, simulating how it behaves under field conditions.
The resulting Current Cycling Test Data provides a clear picture of connector performance over time. Not just the maximum limits, but how those limits move during actual use. That level of transparency helps ensure design reliability long before the first prototype is powered up.
The Power Integrity Certified Badge
The Power Integrity Certified badge identifies products that have gone through this advanced level of testing and documentation. For a connector to earn certification:
- It must pass the Current Cycling Test (EIA-365-55)
- It must provide current carrying capacity and resistance-versus-number-of-contacts data
- It must be available with guidelines to help engineers, based on real test data and proven design parameters
Those guidelines turn complex measurements into practical design insight, helping engineers optimize both connector selection and PCB layout for maximum efficiency. Thus, the Power Integrity Certified badge is more than just a logo. It is evidence of verified performance, backed by data.
Why It Matters
The Power Integrity Certified badge takes some of the uncertainty out of the design process. Engineers can compare products with confidence, knowing the data reflects tested operating behavior. Procurement teams gain an extra layer of assurance that a component will meet its stated specs.
These tests also reflect Samtec’s philosophy, combining rigorous testing with flexibility and accessibility. No minimum order quantities, no long lead times, just transparent information and proven performance.
A Higher Standard, Backed by Data
The Power Integrity Certified program gives engineers a clearer path to reliable design, supported by real data and real-world testing. You can learn more about Power Integrity and explore certified products on the Samtec Power Integrity FAQ page.
