50V 1uf (1000nf) Smd Capacitor 0805

 

If your board needs a 50v 1uf capacitor, and the old part is a 50V ceramic chip in an 0805 body, this is the part to order. It is a 50v 1uf capacitor in a rectangular surface-mount body, built for energy storage, filtering, and voltage regulation in power circuits where a small-value part would not hold enough charge. It fits solar inverters, DC power supplies, DC-DC converters, and voltage stabilisation jobs that need a 50V 1uF part. It does not fit jobs that need a different capacitance value, a higher voltage than 50V, or a through-hole body. Check the checks below before you order, so the value, the voltage, the tolerance, 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. A ceramic capacitor does that job as a flat part that solders straight onto the pads of a board, with metal ends that make the contact. This 50v 1uf part holds its 1uF value within 10%, so a board that calls for 1uF gets between 0.9 and 1.1uF. The 1uF value is the point here: it is large enough to store real charge and smooth the supply, which is why it fits energy storage and decoupling rather than signal work only. The 0805 body is about 2.0 mm long, so it fits boards where a bigger chip still has room. You can check the value from the code: the value code for this part is 105, which reads as 10 followed by 5 zeros, or 1,000,000 picofarads — that is 1 microfarad.

Repair techs use a part like this as a 1uf smd 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, where a steady supply keeps the rest of the board working well, and EMI suppression, where it cuts electrical noise before it spreads. As an X7R part it also works as a decoupling capacitor near power pins, where it steadies the local supply.

Checks before you order

• Value: your board list must call for 1uF. A nearby value is not the same part — if your board needs a different value, stop and check the board list again. A 50V 0.1nF part in a 0603 body is a different value in a smaller body for a different job, not a swap for this one.
• Voltage: the voltage across this part must never go above 50V. If your circuit runs at a higher voltage, this part is the wrong pick — check the board list for the voltage your circuit really needs.
• Tolerance: the real value may sit up to 10% away from 1uF, so between 0.9 and 1.1uF. If your circuit needs tighter than 10%, this part is the wrong pick — do not hope the part you get sits near the middle.
• Temperature change: this is an X7R part, so its capacitance stays within ±15% across −55°C to +125°C. If your circuit needs a steadier value across temperature, check the circuit design first — a part with a different dielectric may be needed.
• DC bias: the real capacitance of a high-value X7R part drops when DC voltage is applied, so allow for that drop in decoupling use. If your circuit needs the full 1uF at the working voltage, check the circuit design first.
• Body and fit: your board must take an 0805 surface-mount body. Measure the old part and match it against the pads and the space on your board. The series body is about 2.00 mm long, 1.25 mm wide, and 1.25 mm high — if your old part is much bigger, check the board list again before you order. A 222PF 2kV ceramic disc capacitor is a high-voltage through-hole part for a different job, not a swap for this one.
• Polarity: this part has no polarity — it fits either way round. If your board list calls for a polar part, this is the wrong pick.

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 50v 1uf is the plain name from its voltage and value. 50v 1uf capacitor is the name buyers use when the full rating matters. 1uf smd capacitor is the name buyers use with the value and the mounting style together. 0805 capacitor is the name buyers use when the body size matters. Ceramic capacitor is the name for its construction type. If your board list calls for 1uF at 50V in an 0805 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 1uF mean, and what is 105?

1uF means 1 microfarad of charge storage. 105 is the value code used in part listings for 1uF: 10 followed by 5 zeros, in picofarads, gives 1,000,000pF, which is 1 microfarad. It does not mean 105 picofarads.

What does X7R mean?

X7R is the dielectric type of this ceramic capacitor. It works from −55°C to +125°C, and its capacitance stays within ±15% across that range. It is a general-purpose dielectric for filtering, decoupling, and energy storage — not a precision dielectric for timing circuits that need a near-constant value.

What does ±10% mean?

It is the tolerance: the real capacitance may sit up to 10% above or below 1uF, so between 0.9 and 1.1uF. If your circuit needs tighter than 10%, this part is the wrong pick.

Can I use this part above 50V?

No. The rated voltage is 50V, and the voltage across the part must stay at or below it. Above that, this part is the wrong pick.

Does the real capacitance stay at 1uF when voltage is applied?

Not exactly. A high-value X7R part loses some capacitance when DC voltage is applied, so the part may read below 1uF at its working voltage. Allow for that drop in your circuit, and check the circuit design if it needs the full 1uF under voltage.

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 50V 1uF (1000nF) SMD capacitor 0805, a surface-mount ceramic capacitor for stable voltage regulation and effective noise suppression in solar inverter applications, for signal filtering and power stability in high-frequency circuits, for energy storage and power regulation, for circuit tuning and EMI suppression, and for DC-DC converters, filtering circuits, and voltage stabilization — and that use still stands.
