THE RCD ADVANTAGE
Why Mission-Critical
Organizations Choose RCD
Certified for what can’t fail
RCD is ISO 9001 certified and ITAR compliant, with documented quality processes designed to deliver consistent results and meet demanding requirements. It’s the rigor engineers need when component performance isn’t something they can leave to chance.

Specialized in Resistors
Resistors are our sole focus. And because you work directly with the people who design and make them, you get responsive engineering support and deep product knowledge that broad-line manufacturers and distributors can’t easily match.
Big enough to support mission-critical programs. Small enough to know yours by name.
U.S.-Based, Without the Wait
RCD gives your program the confidence of a U.S.-based supply chain — without the long lead times that have become the industry norm for highly qualified components.
Our lead times are up to 3x shorter than the closest high-reliability resistor manufacturer. That helps engineering and procurement teams keep critical programs on schedule without compromising quality or traceability.

OUR PEOPLE
The People
Behind the Part
Behind every resistor is a small-but-mighty team in Manchester, New Hampshire that's been solving difficult engineering problems for decades.
This is their story.
Our product isn't glamorous. Most of the time, we're behind the covers — on a circuit board nobody thinks twice about. But when someone flips a switch and it works, that's the moment that matters. You don't see us. We're just there, doing exactly what needs to be done, when it needs to be done.
