CL31B106KBHNNNE 10uF MLCC for Power Filtering and Decoupling

ElecSuppliers Part Number GuideAug 15, 2026

If a PCB needs more capacitance without moving to a larger traditional capacitor, an MLCC is often one of the first options engineers consider.

CL31B106KBHNNNE is a Samsung Electro Mechanics multilayer ceramic capacitor with a nominal capacitance of 10uF. It belongs to the CL31 series and is intended for surface mount PCB assembly.

The part is mainly relevant to power circuits where local capacitance is needed around regulators, processors and other active components.

The 10uF Value

The 106 code in the part number corresponds to 10uF.

That value is commonly found on low voltage power rails. A capacitor in this range can help smooth changes in supply voltage and provide local energy storage when the load changes.

It is not unusual to see a 10uF MLCC used together with smaller capacitors. The larger capacitor handles part of the bulk capacitance requirement while smaller values can be placed closer to an IC for higher frequency bypassing.

Reading the Part Number

The full part number contains more information than just the capacitance.

CL31 identifies the Samsung Electro Mechanics series and package family. The remaining characters define characteristics such as dielectric, capacitance value, tolerance and other ordering information.

This matters when purchasing. A request for a "10uF ceramic capacitor" is not specific enough for a production BOM because there are many versions with different voltage ratings and physical dimensions.

For this reason, CL31B106KBHNNNE should normally be searched and quoted as a complete MPN.

Power Supply Applications

This type of MLCC is particularly useful around power conversion and regulation circuits.

Possible applications include:

• DC power filtering

• Voltage regulator outputs

• DC DC converter circuits

• Processor power rails

• Embedded control boards

• Consumer electronic equipment

The capacitor can be placed near the load or regulator where local capacitance is required.

The actual voltage rating and operating conditions need to be checked against the circuit before the component is approved.

Pay Attention to DC Bias

One point that is easy to overlook with ceramic capacitors is the difference between nominal capacitance and effective capacitance.

The marked 10uF value is measured under specified conditions. When a DC voltage is applied, the actual capacitance of an MLCC can decrease depending on its dielectric and operating voltage.

This becomes more relevant when the capacitor is being used on a power rail. If the circuit depends on a minimum amount of capacitance, engineers should check the capacitor's DC bias characteristics rather than looking only at the value printed in the BOM.

CL31B106KBHNNNE on the PCB

The package size makes this component suitable for surface mount production, but placement still matters.

For a regulator output, keeping the capacitor reasonably close to the relevant power and ground connections can help keep the power path short.

The PCB designer should also use the recommended footprint and assembly conditions for the exact component.

If another 10uF MLCC is being considered as a replacement, both the footprint and effective capacitance should be checked.

Finding CL31B106KBHNNNE Suppliers

For sourcing, use the complete CL31B106KBHNNNE part number rather than searching only for "10uF MLCC."

Supplier quotations should be checked against the original manufacturer, package, capacitance, tolerance, voltage rating and product status.

This is particularly important for high volume production because a visually similar MLCC may not have the same electrical performance.

For buyers building or maintaining an electronics BOM, CL31B106KBHNNNE is a specific Samsung Electro Mechanics MPN worth keeping intact throughout the purchasing process.
