C0G/NP0 Ceramic Capacitors & Mixed-Dielectric MLCCs
Choose C0G/NP0 capacitors by dielectric, value and footprint
NP0 (also written NPO in many seller titles) and C0G identify a Class 1 ceramic dielectric used where relatively stable capacitance is important. This collection is primarily surface-mount multilayer ceramic capacitors (MLCCs), from selected low-pF values to nF values across 0201, 0402, 0603, 0805, 1206, 1210, 1808 and 1812 listings, plus some larger-format options, leaded monolithic ceramics and assortments. However, several shared listings also offer X7R or X5R variants, high-capacitance µF options, and there are unrelated aluminum electrolytic, PPS film and polymer tantalum listings. Collection membership and an NP0 keyword in a product headline do not certify the selected variant as C0G/NP0.
C0G/NP0 versus other options
- C0G/NP0: consider for documented timing, filtering or resonant circuits that need controlled capacitance across temperature and applied DC voltage. Confirm the manufacturer's dielectric specification, tolerance and loss data before claiming RF, precision or high-frequency performance. A seller's “high frequency” label alone gives no usable Q, ESR or frequency limit.
- X7R and X5R: Class 2 ceramics can provide more nominal capacitance for a given size, but effective capacitance varies with DC bias, temperature and aging. The shared NPO/X7R listings require reading the exact variant; a pF/nF/µF value and package do not make these dielectrics interchangeable.
- Other capacitors: leaded monolithic ceramic parts require lead spacing, not an SMD pad footprint. Aluminum electrolytic, PPS film and polymer tantalum products differ in polarity, dielectric, frequency behavior and mounting; they are not NP0 MLCCs.
How to specify an order
- Choose the required nominal capacitance and read the exact pF, nF or µF option. Standard three-digit codes use a pF multiplier: 101 = 100 pF, 102 = 1 nF, 103 = 10 nF and 104 = 100 nF. For small values, markings such as 4P7 mean 4.7 pF. Do not treat a seller's conflicting unit as authoritative.
- Confirm dielectric on the selected variant, not the listing title. Especially verify claims of 100 nF, 220 nF or higher “NP0” values against a manufacturer part number and datasheet; large values, small packages and high voltages need independent confirmation rather than assumed C0G behavior.
- Match the imperial SMD case code to the actual PCB footprint. 0201 imperial is about 0.6 × 0.3 mm (0603 metric); 0402 imperial is about 1.0 × 0.5 mm (1005 metric); 0603, 0805 and 1206 are larger imperial case families. Some listings mix code systems or contain typos, so check dimensions before assembly.
- Verify rated voltage and derating at working bias, capacitance tolerance (absolute pF tolerance versus percent), temperature range, and circuit-specific loss, ESR, Q and self-resonant behavior. A 1 kV, 2 kV or 3 kV option in a shared listing does not rate every variant at that voltage; a high DC voltage rating does not establish X/Y mains safety approval.
- Check quantity and packaging: single-value bags, 10/20/50/100-piece selections, reel quantities and mixed-value kits are different purchasing units. Confirm per-value contents and traceable manufacturer documentation where needed.
Buyer checklist
- Exact variant's capacitance, unit, dielectric and tolerance
- Imperial/metric size, physical dimensions and mounting method
- Rated voltage, applied-bias capacitance and temperature data
- Loss, Q, ESR and self-resonance for frequency-sensitive designs
- Manufacturer part number, source documentation and pack contents
Frequently asked questions
Are NP0, NPO and C0G always different types?
NP0/C0G are commonly used for the same stable Class 1 dielectric category; “NPO” is a frequent spelling in these listings. Still confirm the exact selected part's datasheet and marking.
Is every product on this page NP0?
No. Some selected options are X7R or X5R, and some complete listings use non-ceramic capacitor technologies. Read the individual variant before selecting a replacement.
Does 104J mean 104 pF?
No. Code 104 conventionally means 100 nF, and J conventionally denotes ±5% tolerance where the marking system applies. Confirm the full manufacturer's marking and dielectric separately.
Can a C0G part replace an X7R part of the same nominal value?
Only after verifying the actual capacitance at operating bias, case size, voltage, tolerance, loss and circuit requirements. Nominal value alone does not establish interchangeability.
