How to find the capacitor supplier near me?

2024-07-12

No matter if you are finding a replacement for a capacitor that has gone bad or finding a cross for one that is obsolete there are a couple steps you can take to make finding a replacement easier.

To find a capacitor supplier near your location, you can try the following methods:

1. Online Search: Use search engines like Google and enter keywords such as "capacitor supplier near [your city or area]." This should provide you with a list of nearby suppliers.

2. Yellow Pages: Check local business directories or yellow pages either online or in print. Look under categories like "Electronic Components" or "Electrical Supplies."

3. Electronic Component Distributors: Companies like Digi-Key, Mouser Electronics, and RS Components often have regional warehouses or distribution centers that might be near your location.

4. Local Electronics Stores: Stores that specialize in electronics or electrical supplies might carry capacitors or be able to recommend a nearby supplier.

5. Industry Networks: If you are involved in a specific industry (such as manufacturing or electronics repair), industry associations or forums might have recommendations for local suppliers.

6. Social Media and Forums: Platforms like LinkedIn, Facebook Groups, or specialized forums (such as those related to electronics or electrical engineering) can be valuable for getting recommendations from others in your area.

7. Trade Shows and Events: Local trade shows or events related to electronics or electrical engineering often have exhibitors who are suppliers of electronic components.

By utilizing these methods, you should be able to locate capacitor suppliers near your location efficiently.Here is an example for your reference:

Step 1:

First things first you need to identify as many of the specifications off the capacitor as you can.

Is the capacitor Through-Hole, Surface mount, or Chassis Mount? Most through hole and chassis mount caps with have a capacitance, voltage, and temp listed right on the part. They may also have a manufacturer name and in some instances particularly chassis mount you may even find a part number.

On surface mount electrolytic caps, it is more common to find a cap that simply lists a capacitance number, a voltage or a voltage code, and a lot number or series number. This can be a bit tricky to identify. Start with the capacitance and see if the other numbers appear to be suggesting voltage or if they appear to be more of a lot/series number.

Now that we have these specifications we can look at how you can find options on the Digi-Key site under Aluminum Electrolytic Capacitors.

Step 2

To select In-stock. Also select through Hole and Capacitance if you know these numbers.

Also you should know the temperature on the cap shows 85C. Normally you would select a temp and anything higher, however everything available is 85°C or higher already. you still have many options on this search so you am going to continue to narrow down options. This is a through hole and you want it to go right in my board so you are going to select a 2mm board spacing. If this eliminates all your options there are some ways to bend leads.

you still have a few options on this search so you can look to narrow down options more. you will choose 25V or 16V or 63V . Now you a down to a manageable number and can continue to either filter by price, height, or manufacturer and select a replacement capacitor.

Step 3

Looking at the top of this capacitor you can identify that this is a polarized cap by the black mark. you also suspect that it is a 220uF or 47uF cap, the V is a voltage code, and the CK is a series. Let’s look through the filters and see if we have something that matches.

 you again will go to the Aluminum Electrolytic Caps Section and this time you will choose surface mount, polarized, and 220uF or 47uF and see what you have available.

Now you will have to do a little measuring as the next step to finding a replacement if you have not positively identified the cap is to measure the cap. We can look at the dimension, seated height, and most importantly surface mount land size to ensure it will fit your board.

Once you have verified the physical dimension you will then generally choose the highest temp available if you don’t know the temp rating of the capacitor. Then you can narrow your list again by price, manufacturer, and lifetime @temp if needed.

Conclusion:

Finding a replacement capacitor can be a little tricky, however once you identify the specifications of your existing cap you can easily click through the filters provided on the Digi-Key website and a replacement can be found.
