Stop chasing suppliers and focus on winning. At Ampersand Magnetics, we build custom magnetics and cores that match your spec and arrive on your schedule, not just when the supply chain is stable, but when the world is volatile and the stakes are high. What you get isn't just parts. It's the calm of knowing you have a partner in your corner and the confidence to keep building.
You know how to build a great product. You have the orders. You have customers who are counting on you.
But one outsourced part can put the whole thing at risk.
The quote looks good, then the lead time shifts.
The first order passes, then the next run drifts.
You ask for an update, and the answer comes too late to help.
So your team absorbs the risk. You pad the schedule, chase the updates and spend time managing the supplier instead of building.
We don't go dark when things get tough. We don't stop working until the parts arrive on your dock, in time for your production.
That's partnership: parts that match your spec, lead times you can trust, and a partner who goes the distance for you, each and every time.

Your name is on the drawing. Your magnetics should match it exactly, from first article through final run, so your design performs the way you intended.

A stopped line costs by the minute. Your magnetics should be the component you rarely have to think about: built correctly and always ready when production needs them.

You are measured by what arrives and when. Your supplier should protect your priorities with the same care and urgency you do.

Before we quote, we take time to understand your application, your constraints, and what success looks like for your team. We look beyond the part number so potential issues can be caught on paper instead of in production.

We source, wind, and test to your exact specifications. Once you approve the first article, we lock the process so the part you sign off on is the part you receive in every run after.

We closely monitor every run, deliver on your schedule, and communicate updates before you have to ask. This is where the pressure lifts and the partnership starts to earn your trust.
When your magnetics are handled, you get time and attention back.

“This is amazing work. There is no way we could get the problem resolved so quickly had we tried to contact the supplier directly. You really came through for us.”

“It is easy to manage when everything goes well, but when there is an issue, this is when a company has the chance to shine. You guys rock.”
