ElecSuppliers Part Number GuideAug 22, 2026

CL10B334KPNC is a multilayer ceramic capacitor designed for compact electronic circuits. With a nominal capacitance of 330 nF, it is suitable for power supply decoupling, signal filtering, noise suppression and other general-purpose applications.

The component belongs to the CL series and uses multilayer ceramic capacitor technology. Its compact surface-mount construction makes it suitable for high-density PCB assemblies used in consumer electronics, industrial equipment, communication devices and embedded systems.

CL10B334KPNC Key Specifications

CL10B334KPNC has a nominal capacitance of 330 nF, equivalent to 0.33 µF.

The "334" capacitance code represents 33 followed by four zeros in picofarads, resulting in 330,000 pF or 330 nF.

The component uses X7R ceramic dielectric technology. X7R is widely used for applications where relatively stable capacitance is required across changes in temperature.

The exact voltage rating, tolerance and package should be verified from the complete part number before using the component in a production design.

330nF X7R Ceramic Capacitor

330 nF is a commonly used capacitance value in electronic circuits.

A capacitor with this value can provide useful filtering and decoupling without requiring a large physical package.

In digital circuits, a 330 nF MLCC can be placed near an IC power supply to help suppress high-frequency disturbances.

In analog circuits, it can also be used as part of an RC filter, signal-conditioning network or power-supply filtering stage.

CL10B334KPNC X7R Dielectric

X7R is one of the most widely used Class 2 ceramic capacitor dielectrics.

It provides a good combination of capacitance, package size, temperature stability and cost.

Compared with C0G or NP0 capacitors, X7R can provide substantially higher capacitance in a compact package.

However, X7R capacitors can experience capacitance reduction as the applied DC voltage increases. This effect should be considered when the capacitor is used in power circuits.

CL10B334KPNC MLCC

Multilayer ceramic capacitors are constructed from multiple ceramic and electrode layers.

This multilayer structure allows relatively high capacitance to be achieved in a small component.

MLCCs are also well suited to automated surface-mount production, making them common in high-volume electronic manufacturing.

The compact package allows the capacitor to be positioned close to the circuit node that requires filtering or decoupling.

CL10B334KPNC Applications

A 330 nF X7R MLCC can be used in many types of electronic equipment.

Common applications include power supply decoupling, signal filtering, noise suppression, DC-DC converter circuits, control boards, communication equipment and consumer electronics.

The capacitor can also be combined with other capacitor values to create a wider-band filtering network.

Different capacitance values respond differently across frequency ranges, so using several capacitor values together can be useful in complex power-distribution networks.

Power Supply Decoupling

Power supply decoupling is one of the most common applications for small ceramic capacitors.

When an integrated circuit switches rapidly, its current demand can change within a very short period. These changes can create voltage fluctuations on the power rail.

A capacitor positioned close to the IC can provide a local source of charge and reduce high-frequency voltage disturbances.

For this reason, PCB placement is extremely important. A capacitor located close to the IC power pin generally performs more effectively than the same capacitor connected through long PCB traces.

CL10B334KPNC in DC-DC Converters

Ceramic capacitors are widely used around switching regulators.

A 330 nF capacitor may be used for input filtering, output filtering, control circuitry or high-frequency noise suppression depending on the converter topology.

The correct capacitance and voltage rating depend on the specific regulator design.

When used in switching power supplies, designers should also consider the capacitor's effective capacitance under DC bias and its impedance at the switching frequency.

MLCC DC Bias Effect

One important characteristic of X7R capacitors is DC-bias capacitance loss.

The nominal capacitance is measured under specified test conditions. When a DC voltage is applied, the actual capacitance can become lower.

The amount of capacitance reduction depends on the dielectric material, capacitor construction, rated voltage and applied voltage.

For circuits where the exact capacitance is important, engineers should therefore evaluate the effective capacitance under the actual operating voltage rather than relying only on the nominal 330 nF value.

CL10B334KPNC PCB Layout

The compact size of an MLCC allows it to be placed close to an IC, regulator or other circuit node.

For high-frequency decoupling, short connections are particularly important because PCB traces introduce parasitic inductance.

A short path between the capacitor and power-ground loop can improve high-frequency filtering performance.

The PCB pads should also be designed according to the recommended footprint to ensure reliable soldering during automated assembly.

CL10B334KPNC Replacement

When replacing CL10B334KPNC, the first parameter to check is the 330 nF capacitance value.

The dielectric should also be matched to X7R when the original circuit relies on its temperature and voltage characteristics.

Rated voltage is another critical parameter. A replacement capacitor should have an appropriate voltage rating for the circuit and sufficient margin for transient conditions.

Package size, tolerance and termination characteristics should also be checked before selecting an alternative.

CL10B334KPNC for Compact Electronics

CL10B334KPNC is a 330 nF multilayer ceramic capacitor designed for compact electronic circuits.

Its X7R dielectric provides a practical balance between capacitance, stability and package size, making this type of MLCC suitable for decoupling, filtering and power-management applications.

For new designs, engineers should consider capacitance, voltage rating, DC-bias characteristics, temperature range and PCB layout together. For replacement applications, the complete specification should be matched rather than selecting a capacitor based only on its 330 nF capacitance.
