If you've typed Kemet Dugue into a search bar and ended up here, don't worry—you're not alone. Let's clear up the fog first, then answer the real question: what is a connector, and how do you source one without losing your edge?
Kemet—sometimes written as Kemet Inc. on purchase orders, and sometimes as Kemet Corporation—is one of the better-known names in passive components. According to Yageo's official announcement, Kemet became part of the Yageo group in 2020 (Source: yageo.com, accessed January 2025). The Kemet brand still covers ceramic capacitors, tantalum capacitors, relays, connectors, and MLCCs. So when an engineer searches "what is a connector" next to "Kemet," they're usually trying to get the correct part, fast. In my role coordinating rush orders for a distributor, I've handled dozens of calls like that, including same-day turnarounds for production lines that were stopped.
Let's Clear Up Search Confusion
Search strings are messy. If you landed here with Kemet Dugue, I'm not going to pretend that's a standard product family in the Kemet catalogs I've used. From experience, a phrase like this is usually a distributor name, a mistyped part number, or a personal name that got attached to a quotation. The answer isn't to guess—it's to ask for the part number behind the words.
And if you searched Kemet blood pressure, that's a different brand. The electronics Kemet doesn't sell blood-pressure monitors or supplements. But I understand why it's confusing. The same rule applies: check the actual name on the datasheet before buying.
What Is a Connector?
A connector is an electromechanical component that makes a separable electrical connection between two or more circuits. "Separable" is the key word. A connector is designed to be plugged and unplugged, unlike a soldered joint. You get two main halves—plug and receptacle—with contacts inside and a housing around them. The housing keeps the contacts aligned, the locking feature keeps the halves together, and the plating on the contacts controls how well the current flows.
Connectors come in a wide variety: board-to-board, wire-to-board, FFC/FPC, circular, rectangular, and RF. They all do the same fundamental job, but the specifics vary. Two connectors can look identical and still differ in contact material, plating thickness, housing temperature rating, and keying direction. That's why the first question isn't "what kind of connector do you want?" It's "what's the exact part number, and what is the application?"
Three Sourcing Scenarios: Which One Are You In?
There's no universal sourcing answer. What works for a line-down emergency won't work for a product still in development. I use three buckets to help callers decide quickly.
Scenario A: A Production Line Is Waiting
When I'm triaging a rush order, time and location are the two things that matter. Do we already have a qualified Kemet part number? Is it in stock at an authorized distributor? Can someone get it to the airport before the last pickup?
If a line is down, the first task is not to find the cheapest connector—it's to find the already-qualified component and physically get it to the factory. In March 2024, I coordinated an order for 120 connectors and 40 ceramic capacitors needed the next morning. The factory lead time was fourteen days. We found stock across two distribution centers, paid about $240 in additional freight, and the parts arrived by 8:00 am. The alternative was a client facing a $50,000 penalty for stopping assembly.
In an emergency, get the exact part number and written confirmation of the date code. Ask the distributor to verify the part is not on a manufacturer disruption notice. If you're considering a substitute, require a compatibility statement in writing.
A verbal "that one will work" isn't enough when a line is already dark.
Also check quantity. You don't need to buy a full reel if the authorized distributor has 30 pieces in stock. Rushing a part is stressful enough; don't add a pricing discussion to the middle of it unless you need to.
Scenario B: You're Designing a New Product
If you're still at the prototype stage, the pressure is different. You have time to check the datasheet, request samples, and run the connector through your own mechanical and thermal tests. That's a luxury, and people skip it.
Start with the electrical basics: rated current per contact, rated voltage, contact resistance, operating temperature range, and mating cycles. Then move to mechanical fit: PCB footprint, orientation, keying, locking tab, and insertion force. If the product will live outside, add ingress protection and corrosion resistance to the list.
Ask for a 2D drawing and a 3D model before you build the board. A screenshot isn't enough. That drawing will show you the difference between a through-hole and a surface-mount version, or a connector with a left-side keying versus the right-side one.
Don't feel bad about small orders. I've seen a $200 trial order turn into a $20,000 annual line. A good supplier will take a small prototype order seriously. Today's sample is tomorrow's BOM line.
Scenario C: Legacy Product or Long-Term Capacity
This is the sneaky one. You've been buying the same Kemet connector or capacitor for years. You reorder by muscle memory. That's when a hidden change catches you.
Last year, a client ordered the same part number they'd used for three years. The part looked identical, but the material set had changed slightly. It worked in some batches and failed in others. We eventually traced it to a production change notice no one had reviewed. The lesson: re-verify date codes and PCNs, even for "known good" parts.
For critical, long-life products, build a small inventory buffer. A discontinued part is painful; a discontinued part with no stock and a 12-week lead time can raise your blood pressure quickly. That's why I recommend a quarterly review of any component you couldn't replace without a redesign.
How to Tell Which Scenario You're In
Use a ten-minute test. Answer three questions:
- Do we already have an approved part number for this application?
- Can the production line run for another week without this component?
- Are we willing to pay more for faster delivery?
If you have an approved part, can't wait, and need it now, that's Scenario A. If you have time and are still evaluating options, that's Scenario B. If you've already used the part for years and just need to keep the pipeline full, that's Scenario C. The goal isn't to label yourself perfectly. It's to know which questions matter before you call a supplier.
Bottom Line
Search terms like "Kemet Inc.", "Kemet Dugue", and "blood pressure" are useful only if they lead you to the right place. The right place for an electronics buyer is a datasheet, an authorized distributor, and a clear part number. A connector is not just a piece of metal; it's an interface that has to survive production, shipping, and years of use.
As of January 2025, Kemet remains an active brand under Yageo. Use the official Kemet or Yageo resources to verify part numbers and stock. And when someone asks "what is a connector?", the best short answer is: something you should never order by guesswork.
