50V 0.1nF (100PF) SMD Capacitor 0603

If your board needs a 100pF 0603 SMD capacitor, and the old part is a 50V ceramic chip in a 0603 body, this is the part to order. It is a 100pF 0603 SMD capacitor (0.1nF) 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. A 100pF 0603 SMD capacitor like this one suits high-frequency signal work.

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 100pF 0603 SMD capacitor holds its 100pF (0.1nF) value, so a board that calls for 0.1nF gets the value it needs. The small value is the point here: 0.1nF passes high-frequency signals and blocks low-frequency ones, which is why it fits signal filtering and circuit tuning rather than energy storage. The 0603 body is only about 1.6 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. A 100pF 0603 SMD capacitor is the part to use when the board list calls for 100 pF in a 0603 body.

Key features: 100pF (0.1nF) capacitance; 50V rated voltage; ceramic dielectric, surface mount; 0603 body: about 1.60 mm × 0.80 mm × 0.80 mm; non-polarized — fits either way round; value code 101.

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. 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. Order a 100pF 0603 SMD capacitor only when the value and voltage match your board list.

Tolerance — check the tolerance your board list allows against the tolerance on the product page and the Download file. If your circuit needs a tight tolerance, do not hope the part you get sits near the middle. Body and fit — your board must take a 0603 surface-mount body. Measure the old part and match it against the pads and the space on your board. The series body is about 1.60 mm long, 0.80 mm wide, and 0.80 mm high — if your old part is much bigger, check the board list again before you order.

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 — 0.1nF holds almost no charge. Match the value first, then the voltage, then the body.

Other names for the same part (good to know): Shoppers and repair techs call this same part by a few names. 50V 0.1nF 0603 is the plain name from its voltage, value, and body size. 50V 0.1nF capacitor is the name buyers use when the full rating matters. 100pF capacitor is the name buyers use with the value in picofarads. SMD capacitor 0603 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 0.1nF at 50V in a 0603 body, this page is the right match. Do not judge by size alone — check the value, the voltage, and the body too. Buyers looking for a 100pF 0603 SMD capacitor will find the right part on this page.

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 used in part listings for 100pF: 10 followed by 1 zero, or 100 picofarads.

What does 50V mean for this part? 50V is the rated voltage: the highest DC voltage the part is made to stand across in normal use. The voltage across the part must stay at or below 50V.

Is this capacitor polar? No. It is a ceramic chip capacitor, so it has no polarity and fits either way round. If your board list calls for a polar part, this is the wrong pick.

Can I use a different value, like a nearby picofarad part? No, not without checking the circuit. The capacitance value sets how the part filters signals and tunes the circuit, 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. Match the board list exactly when you order a 100pF 0603 SMD capacitor.

How do I fit a 0603 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 1.6 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. A 100pF 0603 SMD capacitor solders flat onto the matching 0603 pads.

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 0603, a small surface-mount ceramic capacitor for stable signal filtering and voltage regulation in solar inverter applications, for high-frequency circuits, for easy surface mounting on space-constrained PCBs, for energy transfer and noise reduction, for voltage stabilisation and EMI suppression, and for efficient power conversion — and that use still stands.
