CL21B106KOQNNNE MLCC Specifications and Supplier Information

ElecSuppliers Part Number GuideAug 15, 2026

CL21B106KOQNNNE is a multilayer ceramic capacitor from Samsung Electro Mechanics. It is part of the company's CL series of chip ceramic capacitors and is intended for applications where compact surface mount capacitors are required.

The complete part number contains information that helps identify the capacitor's electrical characteristics and physical configuration. This makes the full MPN particularly useful when matching components against an electronic BOM.

What Does CL21B106KOQNNNE Represent?

The part number provides several clues about the component.

The CL21 designation is associated with the capacitor's size classification, while 106 corresponds to a nominal capacitance of 10 µF. The remaining characters identify additional electrical and ordering characteristics.

For procurement and engineering teams, using the entire CL21B106KOQNNNE number is preferable to searching only for a generic 10 µF ceramic capacitor because voltage rating, dielectric characteristics, tolerance and package size can all affect whether a capacitor is suitable for a particular design.

CL21B106KOQNNNE Capacitor Characteristics

CL21B106KOQNNNE is a surface mount MLCC designed for PCB applications. Its 10 µF capacitance makes it relevant to circuits that require relatively high capacitance in a compact ceramic capacitor format.

When evaluating this component, designers should pay attention to capacitance, rated voltage, capacitance tolerance, dielectric material, temperature characteristics and package dimensions.

For ceramic capacitors, the effective capacitance can change under operating conditions such as applied DC voltage and temperature. The manufacturer's electrical specifications should therefore be checked when the capacitor is being used in a power-sensitive circuit.

Where CL21B106KOQNNNE Can Be Used

A 10 µF MLCC can serve several functions in electronic equipment.

Depending on the circuit design, CL21B106KOQNNNE may be considered for power supply filtering, local decoupling, voltage stabilization and general energy storage on PCB assemblies.

Its suitability depends on the required voltage, capacitance stability, operating temperature and available PCB space.

CL21B106KOQNNNE Package

The physical size represented by the CL21 series designation is an important consideration when designing the PCB footprint.

For engineers replacing an existing capacitor, both the electrical characteristics and package dimensions need to match the original design. A capacitor with the same nominal capacitance is not necessarily a suitable replacement if its voltage rating, dielectric characteristics or physical size are different.

Sourcing CL21B106KOQNNNE

When searching for CL21B106KOQNNNE suppliers, buyers should use the complete part number rather than simply searching for “10uF MLCC”.

The exact MPN allows suppliers to identify the intended capacitor more accurately and helps buyers compare availability, manufacturer information, packaging and purchasing quantities.

ElecSuppliers provides electronic component product and supplier information, giving buyers a way to locate suppliers associated with specific capacitor part numbers.

For production sourcing, the complete CL21B106KOQNNNE designation should remain in the BOM and purchasing documentation to reduce the risk of receiving a capacitor with different electrical characteristics.
