103PF 1kv dip Ceramic Capacitor

 

If your board needs a 103pf 1kv capacitor, and the old part is a 0.01uF ceramic disc rated at 1kV with radial leads, this is the part to order. It is a 103pf 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 0.01uF 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 103pf 1kv part holds its 0.01uF value within 10%, so a board that calls for 0.01uF gets between 0.009 and 0.011uF. 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 103, which reads as 10 followed by 3 zeros, or 10,000 picofarads — that is 0.01 microfarads. It does not mean 103 picofarads.

Repair techs use a part like this as a 0.01uf 1kv capacitor for high-frequency filtering, where it lets the wanted signal through and blocks the rest, and for snubber circuits, where it soaks up voltage spikes before they can damage the rest of the board. It also fits noise suppression, where it cuts electrical noise before it spreads, and voltage stabilization, where it steadies the supply. 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 0.01uF (10nF), which is the part marked 103. If your board list calls for 103 picofarads, that is a different, far smaller part — stop and check the board list again. The code 103 is 10,000 pF, not 103 pF. A 102PF 1kV dip ceramic 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 0.01uF, so between 0.009 and 0.011uF. 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 222PF 2kV ceramic disc capacitor is a different value at a higher voltage 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, 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. 103pf 1kv is the plain name from its code and its voltage. 103pf 1kv capacitor is the name buyers use when the full rating matters. 0.01uf 1kv capacitor is the name buyers use with the value in microfarads. 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 0.01uF at 1kV in a radial disc body, this page is the right match. Do not judge by the name alone — 103 is the code for 10,000pF, not 103 picofarads — check the value, the voltage, and the lead spacing too.

Frequently Asked Questions

What does 103 mean — is it 103 picofarads?

No. 103 is the value code for 10,000 picofarads, which is 10 nanofarads or 0.01 microfarads. Under the standard 3-digit code, 103 means 10 followed by 3 zeros, in picofarads. The name “103PF” is the code, not the value in picofarads.

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 103PF (0.01UF) 1KV DIP ceramic capacitor, a high-voltage ceramic capacitor for stable power regulation and efficient circuit performance in solar inverter applications, for high-frequency filtering, noise suppression, and voltage stabilization, for DC-DC converters, snubber circuits, and EMI suppression, for handling voltage spikes and power surges, and for solar inverters, power supplies, and industrial control systems — and that use still stands.
