CL31B106KBHNNNE 10uF X7R Ceramic Capacitor for Power Supply Applications

ElecSuppliers Part Number GuideAug 15, 2026

The CL31B106KBHNNNE is a Samsung Electro Mechanics multilayer ceramic capacitor from the CL31 series.

The part number is commonly associated with a 10uF MLCC in a larger surface mount package than the very small ceramic capacitors often used for high frequency bypassing.

That makes it more suitable for applications where the designer needs a useful amount of capacitance close to a power rail while still keeping the PCB reasonably compact.

Where This Capacitor Makes Sense

A 10uF ceramic capacitor is often used around power circuits rather than as a general purpose signal component.

It can provide local energy storage and help smooth changes on a supply line. You may find this type of capacitor near voltage regulators, DC DC converters, processors and other circuits with changing current demand.

It is also common to combine a 10uF MLCC with smaller values such as 100nF or 1uF. The different capacitor values work together across different parts of the frequency range.

The CL31 Series

The CL31 designation is important when identifying the physical and electrical characteristics of the component.

A search for "10uF ceramic capacitor" will return thousands of possibilities. They can have different voltage ratings, tolerances, dielectric materials and package sizes.

For an existing PCB, those differences matter.

Using the complete CL31B106KBHNNNE part number makes it much easier for purchasing teams and engineers to locate the intended component rather than receiving a visually similar capacitor with different specifications.

What Does 106 Mean

The 106 portion of the part number identifies the nominal capacitance value.

For this component, that corresponds to 10uF.

The rest of the ordering code carries additional information about the capacitor. This is why replacing the part based on the "10uF" value alone is not recommended.

Two 10uF MLCCs can behave quite differently when they are subjected to the same DC voltage.

DC Bias Is Worth Checking

Ceramic capacitors have a characteristic that can cause confusion during component selection.

The nominal capacitance is normally measured under specified test conditions. Once the capacitor is operating on a real DC power rail, the effective capacitance can be lower.

The amount of change depends on the capacitor construction and the voltage applied across it.

If a circuit requires a certain amount of effective capacitance for stable regulator operation, engineers should therefore check the manufacturer's DC bias data instead of relying only on the nominal 10uF value.

Typical Uses of CL31B106KBHNNNE

This type of MLCC can be considered for:

Power rail decoupling

Voltage regulator circuits

DC DC converters

Power filtering

Embedded control boards

Consumer electronics

Industrial electronic equipment

The best application depends on the actual voltage, temperature, ripple current and capacitance requirements of the circuit.

PCB Placement

The physical location of a power capacitor can be just as important as its capacitance.

When CL31B106KBHNNNE is used around a regulator or converter, placing it close to the relevant power and ground connections can help keep the current loop short.

The recommended land pattern should be followed during PCB design. Ceramic capacitors are also relatively brittle compared with many other passive components, so excessive mechanical stress during board assembly should be avoided.

Finding the Right Replacement

If CL31B106KBHNNNE becomes difficult to source, the replacement should be selected by comparing the complete specification rather than simply looking for another 10uF MLCC.

Capacitance, voltage rating, dielectric, tolerance, package dimensions and effective capacitance under operating voltage are all worth checking.

For an existing production board, the replacement should also be tested under actual operating conditions before being added to the approved BOM.

CL31B106KBHNNNE Supplier Search

For purchasing, search for the complete CL31B106KBHNNNE MPN.

This is more precise than searching for "Samsung 10uF capacitor" or "10uF ceramic capacitor," especially when a production line needs the exact component.

Supplier quotations should include the complete manufacturer part number so that package and electrical specifications can be checked before an order is placed.

For compact power circuits that need a 10uF MLCC, CL31B106KBHNNNE is a specific component worth evaluating when its full electrical and mechanical characteristics match the design.
