16V 220uF aluminum electrolytic capacitor

If your board needs a 16v 220uf capacitor, and the old part is a 16V aluminum electrolytic part with radial leads, this is the part to order. It is a 16v 220uf capacitor in a radial through-hole body, built for energy storage, filtering, and voltage regulation in low-voltage circuits where a small-value part would not hold enough charge. It fits solar inverters, DC link circuits, power conditioning boards, and TV, VCD, and speaker circuits that need a 16V 220uF part. It does not fit jobs that need a different capacitance value, a higher voltage than 16V, a surface-mount body, or a non-polar capacitor. Check the checks below before you order, so the value, the voltage, the polarity, and the body all match your board.

This is an original, high-quality part.

What it does

A capacitor stores electrical charge and gives it back when the circuit needs it. An aluminum electrolytic capacitor does that job with a high capacitance in a small body, which is why it is used for energy storage and for smoothing voltage on power boards. This 16v 220uf part holds its 220uF value within 20%, so a board that calls for 220uF gets between 176 and 264uF. The 220uF value is what sets it apart from the small-value capacitors used for signal work only — it can hold enough charge to smooth the supply and keep the voltage steady under load.

Repair techs use a part like this as a 16v 220uf capacitor for energy storage, where it holds charge for the next stage, and for filtering, where it smooths out voltage ripples so the circuit sees a steady level. It also fits voltage regulation and DC link circuits, where a steady supply keeps the rest of the board working well.

Checks before you order

• Value: your board list must call for 220uF. A nearby value is not the same part — if your board needs a different value, stop and check the board list again. A 25V 330uF part is a different value for a different job, not a swap for this one.
• Voltage: the voltage across this part must never go above 16V. If your circuit runs at a higher voltage, this part is the wrong pick — a 200V 47uF part is a different job in a high-voltage circuit, not a swap for this one.
• Polarity: this is a polar capacitor. The negative terminal is marked on the sleeve — match the mark to your board before you solder, and never reverse the polarity. Reversed polarity can damage the capacitor and the board.
• Tolerance: the real value may sit up to 20% away from 220uF, so between 176 and 264uF. If your circuit needs tighter than 20%, this part is the wrong pick — do not hope the part you get sits near the middle.
• Body and fit: your board must take a radial through-hole body with 5 mm hole spacing. Measure the old part and match it against the holes and the space on your board. The live page states 10 mm across and 20 mm long — if your old part is much smaller, check the board list again before you order, because the series standard size for this value is smaller.
• Fit for the job: this part is made for steady filtering and energy storage, not for circuits that charge and discharge it again and again at speed — aluminum electrolytic capacitors are not made for that kind of job.

Specifications

All figures below are from the maker series documents for this capacitor family, except the body size, the lead spacing, and the temperature range, which are from the live page and agree with the series. No figure here was guessed. The maker of the exact part on this page is not stated on the live page, so the publisher should confirm the series figures against the Download file at publish time (see the gates note).

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 16v 220uf is the plain name from its voltage and value. 16v 220uf capacitor is the name buyers use when the full rating matters. Aluminum electrolytic capacitor is the name for its construction type. 220uf capacitor is the short name buyers use when the value is the key point. 16v capacitor is the short name buyers use when the voltage is the key point. If your board list calls for 220uF at 16V in a radial body, this page is the right match. Do not judge by size alone — check the value, the voltage, and the body too.

Frequently Asked Questions

What does 16V 220uF mean?

16V is the rated voltage: the highest DC voltage the part is made to stand across in normal use. 220uF is the capacitance: 220 microfarads of charge storage. Both numbers must match your board list.

Is this capacitor polar?

Yes. It is a polar aluminum electrolytic capacitor, so it has a positive and a negative lead. The negative side is marked on the sleeve. Never reverse the polarity — fit it the way your board marks it.

What is the body size of this part?

The live page states 10 mm across and 20 mm long, with 5 mm hole spacing. Measure your old part and compare it with those figures before you order, and check the holes on your board.

Can I use a 220uF capacitor rated for a lower voltage?

No. If your circuit runs at up to 16V, a lower-voltage part can fail. Always match or exceed the voltage your circuit needs, and check the body still fits your board.

Can I use a different value, like a nearby microfarad part?

No, not without checking the circuit. The capacitance value sets how much charge the part stores and how well it smooths voltage, so a different value changes how the circuit behaves. Only swap in a different value if the circuit design allows it — otherwise match the board list exactly.

What is the price of this part?

Check the live price on the website. The price shown on the product page is the current one.

Use note kept from the old page: this part was listed before as a capacitor for efficient energy storage and voltage regulation in solar inverters, with smooth power delivery, less voltage fluctuation, and better system efficiency, used in DC link circuits, filtering applications, and power conditioning, with a high working temperature range from −40°C to +105°C, and widely used in TV, VCD, and speaker circuits — and that use still stands.
