50V 0.1nF (100PF) SMD Capacitor 0805

If your board needs a 50v 0.1nf capacitor, and the old part is a 50V ceramic chip in an 0805 body, this is the part to order. It is a 50v 0.1nf capacitor in a small rectangular surface-mount body, built for signal filtering and voltage regulation in high-frequency circuits where a large-value part would be the wrong pick. It fits solar inverters, DC power supplies, and circuit tuning jobs that need a 50V 100pF 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 small flat part that solders straight onto the pads of a board, with metal ends that make the contact. This 50v 0.1nf part holds its 100pF value within 10%, so a board that calls for 100pF gets between 90 and 110pF. The small value is the point here: 100pF passes high-frequency signals and blocks low-frequency ones, which is why it fits signal filtering and circuit tuning rather than energy storage. The 0805 body is only about 2.0 mm long, so it fits boards where space is tight.

Repair techs use a part like this as a 100pf capacitor for signal filtering, where it lets the wanted signal through and blocks the rest, and for circuit tuning, where a small fixed value sets how the circuit responds. It also fits voltage regulation, where it steadies the supply, and EMI suppression, where it cuts electrical noise before it spreads. You can check the value from the code: the value code for this part is 101, which reads as 10 followed by 1 zero, or 100 picofarads.

Checks before you order

• Value: your board list must call for 100pF (0.1nF). A nearby value is not the same part — if your board needs a different value, stop and check the board list again. A 50V 1nF part in a 0603 body is a different value 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 100pF, so between 90 and 110pF. 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.
• 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 0.60 mm high — if your old part is much bigger, check the board list again before you order. A 50V 10uF part in a 1206 body is a different value in a bigger body 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.
• Fit for the job: do not use this small-value part where the circuit needs real energy storage — 100pF holds almost no charge. Match the value first, then the voltage, then the body.

Specifications

All figures below are from the maker series documents for this ceramic capacitor family, with the dielectric, tolerance and temperature range confirmed by the live page. 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. 50v 0.1nf is the plain name from its voltage and value. 50v 0.1nf capacitor is the name buyers use when the full rating matters. SMD capacitor 0805 is the name buyers use when the body size matters. 100pf capacitor is the name buyers use with the value in picofarads. Ceramic capacitor is the name for its construction type. If your board list calls for 100pF 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 0.1nF mean, and what is 101?

0.1nF means 0.1 nanofarads, which is the same as 100 picofarads. 101 is the value code printed in part listings for 100pF: 10 followed by 1 zero, in picofarads, gives 100pF.

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, tuning, and decoupling — 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 100pF, so between 90 and 110pF. 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.

How do I fit an 0805 chip capacitor?

Solder it onto the matching pads on the board — it has no leads, so it sits flat on the pads. Check the pad spacing against the 2.0 mm body before you solder, use a fine tip and a small amount of solder, and do not overheat the part. A magnifier helps, because the part is very small.

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 0.1nF (100pF) SMD capacitor 0805, a small surface-mount ceramic capacitor for precise signal filtering and stable voltage regulation in solar inverter applications, for high-frequency circuits, for easy surface mounting on densely packed PCBs, for energy storage and noise reduction, for EMI suppression, voltage stabilisation, and circuit tuning — and that use still stands.
