CL21A106KAYNNNE Capacitor Specifications Applications and Suppliers

ElecSuppliers Part Number GuideAug 15, 2026

CL21A106KAYNNNE is a multilayer ceramic capacitor from Samsung Electro Mechanics. It is part of the CL series of surface mount ceramic capacitors and is intended for electronic designs that require compact capacitance on a PCB.

For engineers searching by MPN, the complete CL21A106KAYNNNE designation is more useful than a generic search for a ceramic capacitor because the individual characters identify important characteristics of the component.

CL21A106KAYNNNE Capacitance

The 106 section of the part number represents a nominal capacitance of 10 µF.

A 10 µF MLCC can be used in power supply filtering and local decoupling applications where a relatively high capacitance value is required in a surface mount package.

The actual capacitance available during operation can vary depending on voltage, temperature and other conditions. Therefore, engineers should evaluate the manufacturer's specifications rather than relying on the nominal 10 µF value alone.

Understanding CL21A106KAYNNNE

The part number contains several identifiers that distinguish this capacitor from other CL series products.

The CL21 portion identifies the series and size configuration.

The 106 portion indicates 10 µF capacitance.

The remaining characters provide additional information related to tolerance, voltage, dielectric characteristics and ordering configuration.

This makes the complete MPN important when the component is being purchased for an existing PCB design.

CL21A106KAYNNNE Applications

A 10 µF ceramic capacitor can serve several functions in modern electronic equipment.

CL21A106KAYNNNE may be considered for power rail filtering, supply decoupling and voltage stabilization in PCB based electronic systems.

It can be used alongside smaller value capacitors where different frequency ranges need to be addressed in a power supply network.

The appropriate capacitance, voltage rating and effective capacitance under DC bias should be checked according to the circuit requirements.

CL21A106KAYNNNE PCB Considerations

The physical dimensions of an MLCC are important when designing the PCB footprint.

Before placing CL21A106KAYNNNE into a production design, engineers should confirm the recommended land pattern and package dimensions. This is particularly important when replacing another 10 µF capacitor.

Two capacitors can share the same nominal capacitance while having different voltage ratings, package sizes or dielectric characteristics.

CL21A106KAYNNNE Supplier Information

For buyers looking for CL21A106KAYNNNE suppliers, the complete part number should be included in sourcing requests.

Supplier quotations should be checked against the exact manufacturer part number, electrical specifications, packaging requirements and quantity.

ElecSuppliers provides electronic component product and supplier information to help buyers locate sources for specific MPNs.

When CL21A106KAYNNNE is listed on a BOM, retaining the complete part number throughout procurement helps reduce the risk of receiving a different 10 µF MLCC that does not meet the original design requirements.
