100PF 1kv Dip Ceramic Capacitor

If your board needs a 100pf 1kv capacitor, and the old part is a 100pF ceramic disc rated at 1kV with radial leads, this is the part to order. It is a 100pf 1kv capacitor in a round disc body with two leads, built as a high-voltage ceramic capacitor for filtering, noise suppression, and voltage stabilization in high-voltage circuits where a low-voltage part would fail. It fits solar inverters, DC-DC converters, snubber circuits, and EMI suppression jobs that need a fixed 100pF value at up to 1kV. It does not fit jobs that need a different capacitance value, a higher voltage than 1kV, or a surface-mount body. Check the checks below before you order, so the value, the voltage, the tolerance, and the lead spacing 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 disc capacitor does that job as a round flat disc with a lead on each side, which solders straight into the holes of a board. This 100pf 1kv part holds its 100pF value within 10%, so a board that calls for 100pF gets between 90 and 110pF. The 1kV rating is what sets it apart from the low-voltage ceramic capacitors used on logic boards — it can stand across a high-voltage stage without damage, as long as the voltage limits below are respected. 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 — that is 0.1 nanofarads.

Repair techs use a part like this as a 0.1nf 1kv capacitor for high-frequency filtering, where it lets the wanted signal through and blocks the rest, and for transient voltage suppression, where it soaks up sudden voltage peaks before they can damage the rest of the board. It also fits snubber circuits, where it tames switching spikes, and EMI suppression, where it cuts electrical noise before it spreads. The disc is ceramic with silver-plated sides, and the leads are tinned copper-clad steel wire.

Checks before you order

• Value — read the code: your board list must call for 100pF (0.1nF), which is the part marked 101. Do not read the code as 100pF by mistake — code 100 would be only 10pF, a different, far smaller part. A 220PF 1kV dip capacitor is a different value for a different job, not a swap for this one.
• Voltage: the voltage across this part must never go above 1kV. 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.
• Body and fit: your board must take a radial disc with two leads about 12.5 mm apart. Measure the old part and match it against the holes and the space on your board. The disc is about 10 mm across — if your old part is much bigger or smaller, check the board list again before you order. A 470PF 1kV dip ceramic capacitor is a different value 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: this part suits high-voltage filtering, transient voltage suppression, snubber circuits, and EMI suppression. If your job needs a safety capacitor across the mains or a much larger value for bulk energy storage, this part is the wrong pick — match the board list exactly.

Other names for the same part (good to know)

Shoppers and repair techs call this same part by a few names. 100pf 1kv is the plain name from its value and its voltage. 100pf 1kv capacitor is the name buyers use when the full rating matters. 0.1nf 1kv capacitor is the name buyers use with the value in nanofarads. Ceramic disc capacitor is the name for its shape and construction. 1kv ceramic capacitor is the short name from its voltage rating. If your board list calls for 100pF at 1kV in a radial disc body, this page is the right match. Do not judge by the code alone — 101 is the code for 100pF, while 100 would be only 10pF — check the value, the voltage, and the lead spacing too.

Frequently Asked Questions

What does 101 mean, and what is 100pF?

101 is the value code for 100 picofarads, which is 0.1 nanofarads or 0.0001 microfarads. Under the standard 3-digit code, 101 means 10 followed by 1 zero, in picofarads. Code 100 would be only 10pF — a different part — so check the marking on the disc before you order.

What does 1kV mean for this part?

1kV is the rated voltage: the highest voltage the part is made to stand across in normal use, which is 1000 volts. The voltage across the part must stay at or below 1kV.

Is this capacitor polar?

No. It is a ceramic disc 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 soaks up spikes, 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.

How do I fit a disc capacitor?

Push the two leads through the matching holes on the board and solder them. Check the lead spacing against the holes before you solder — the live page states about 12.5 mm, so measure the old part rather than guessing from the value alone. Keep the disc clear of parts that cannot take heat.

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 100PF 1kv dip ceramic capacitor, a high-voltage ceramic capacitor for solar inverter and power electronics applications, for stable capacitance, for high-frequency filtering and transient voltage suppression, for DC-DC converters, snubber circuits, and EMI suppression, and for handling voltage spikes and protecting sensitive components — and that use still stands.
