CL21A106KOQNNNE Overview
What is an MLCC? A multilayer ceramic capacitor (MLCC) is a surface-mount passive component constructed from alternating layers of ceramic dielectric and metal electrodes, sintered into a monolithic block and terminated with nickel-barrier solderable end caps. MLCCs are the most widely used capacitors in modern electronics, serving roles in power decoupling, energy storage, AC line filtering, and DC-link bypass. They sit within the broader capacitor family (ceramic -> MLCC -> Class II -> X5R) and are categorized by dielectric class (Class I: C0G/NP0; Class II: X5R, X7R, Y5V) where X5R indicates ±15% capacitance variation over the -55C to +85C operating range.
Key features of the CL21A106KOQNNNE include the 0805 (2.0 mm x 1.25 mm) footprint for compact PCB layouts, X5R dielectric for stable bulk capacitance across temperature, 10% capacitance tolerance for general-purpose decoupling, and 16V rating providing ~2x derating headroom for typical 3.3V and 5V rails. The Ni-barrier + Sn plating supports lead-free reflow soldering at 260C peak per JEDEC J-STD-020.
Typical applications include IC power-rail decoupling (microcontroller VDD, SoC core supplies), bulk bypass on 5V and 12V regulators, smoothing capacitors in DC-DC converter input/output filters, and general-purpose energy storage in handheld battery-powered products. The 0805 size is widely accepted as a sweet spot between miniaturization and manufacturability.
When designing with this part, apply standard 50% voltage derating (so 16V part on a 5V rail provides a 3.2x safety margin), account for DC bias capacitance loss (X5R typically loses 30-50% of nominal value under DC bias at high ratios), and place decoupling capacitors within 2-3 mm of IC supply pins.

Typical Applications
CL21A106KOQNNNE is suitable for 7 applications: Microcontroller Power Rail Decoupling, 5V Power Rail Bulk Decoupling, DC-DC Converter Output Filter, USB and Peripheral Supply Filtering, Battery-Powered Handheld Device Energy Storage, Industrial Sensor Signal Conditioning, Automotive Infotainment Decoupling.
Microcontroller Power Rail Decoupling
The CL21A106KOQNNNE is well suited for microcontroller VDD decoupling where its 10uF bulk capacitance, ±10% tolerance, and 16V rating provide adequate energy storage and noise suppression between the IC supply pin and ground. Placed within 2-3 mm of the MCU VDD pin with a parallel 0.1uF X7R high-frequency bypass, the 10uF X5R handles mid-frequency switching transients and bulk decoupling during MCU load steps. The X5R dielectric gives ±15% capacitance variation across -55C to +85C, comfortably covering industrial MCU operating ranges. The 16V rating ensures 3.2x derating margin on 5V rails and 1.6x margin on 10V rails, well above the 50% derating recommendation.
Recommended
5V Power Rail Bulk Decoupling
For 5V power-rail decoupling on USB, peripheral, and mixed-signal IC supplies, the CL21A106KOQNNNE delivers 10uF at 16V rated voltage, giving a 3.2x derating safety margin. The 0805 footprint is the industry-standard size for hand-solder rework and high-volume pick-and-place assembly. Compared with tantalum alternatives, the X5R ceramic has lower ESR at high frequency (1 MHz and above), is non-polarized, and costs a fraction of equivalent polymer-tantalum. The 10uF capacitance is sufficient to suppress transient voltage drops during 5V regulator load steps of 100-300 mA in USB and sensor-interface subsystems.
Recommended
DC-DC Converter Output Filter
In DC-DC buck and LDO output filters, the CL21A106KOQNNNE's 10uF capacitance smooths switching ripple from the converter's PWM edges and provides bulk energy storage during load transients. Placed at the converter output node, the X5R dielectric is preferred over X7R for cost-sensitive designs while still maintaining ±15% capacitance stability across industrial temperature ranges. The 16V rating supports 12V intermediate rails and even low-voltage 5V outputs with 3.2x margin. Engineers should consider DC bias capacitance loss - at 5V applied the effective capacitance drops to approximately 7-8uF, requiring either oversizing (the bulk capacitance 22uF part) or acceptance of the 30% derating in the design margin.
Recommended
USB and Peripheral Supply Filtering
The CL21A106KOQNNNE is commonly used on USB VBUS and 5V peripheral supply lines where 10uF bulk capacitance is required for inrush current limiting on hot-plug events. The 0805 size fits standard USB connector footprint designs, and the 16V rating handles 5V VBUS plus inductive switching transients from cable ESD events. For USB 2.0 high-speed data lines, the 10uF bulk cap pairs with a smaller 0.1uF X7R for high-frequency noise filtering. The X5R temperature characteristic accommodates consumer and industrial operating ranges without significant capacitance drift.
Recommended
Battery-Powered Handheld Device Energy Storage
For battery-powered handheld products running on 3.7V Li-ion cells, the CL21A106KOQNNNE provides 10uF bulk capacitance at 16V rated voltage with sufficient margin to handle transient voltage spikes from DC-DC converters. The 0805 size keeps the PCB area minimal, and the X5R dielectric is preferred for cost-sensitive consumer designs where tight capacitance tolerance is not critical. The MSL 1 moisture sensitivity level simplifies assembly-line handling. Compared with aluminum polymer capacitors of equivalent capacitance, the ceramic CL21A106KOQNNNE offers longer operational life and lower ESR at switching frequencies above 1 MHz.
Recommended
Industrial Sensor Signal Conditioning
In industrial sensor signal-conditioning boards, the CL21A106KOQNNNE is used for analog supply rail filtering and ADC reference bypass. The X5R dielectric's ±15% tolerance over -55C to +85C is acceptable for general-purpose analog rails where the ADC reference voltage is generated by a separate precision regulator. The 0805 footprint is well suited for dense sensor PCBs and is preferred over smaller 0402 because of the 10uF capacitance target - smaller packages cannot economically deliver 10uF at 16V. The lead-free Ni-Sn plating supports 260C peak reflow for standard SMT assembly.
Recommended
Automotive Infotainment Decoupling
Within automotive infotainment head units and telematics modules, the CL21A106KOQNNNE's 16V rating handles 12V battery rail transients including load-dump and jump-start events when paired with upstream TVS protection. The 0805 size is the industry-preferred package for body-control and infotainment decoupling. The X5R dielectric's ±15% variation over -55C to +85C covers the automotive grade-2 operating range. For full AEC-Q200-qualified equivalent parts, designers should consider AEC-Q220 'Samwha' or 'Murata' automotive-grade MLCC variants with explicit Q200 qualification marking - the standard Samsung CL21A106KOQNNNE is consumer/industrial grade.

Design Notes
DC bias capacitance loss is the most common design pitfall for the CL21A106KOQNNNE. As an X5R dielectric, applied DC voltage causes the effective capacitance to drop significantly. Estimated: at the full 16V rated voltage, effective capacitance can drop to 50-60% of nominal (5-6uF instead of 10uF); at 5V (31% of rated), drop is approximately 20-30% (7-8uF effective). Engineers should oversize bulk capacitance by 30-50% or select a higher-voltage rated alternative like the CL21A106KAYNNNG (25V) for 12V applications.
Place the CL21A106KOQNNNE within 2-3 mm of the IC supply pin it decouples. Use a parallel 0.1uF X7R (0402 or 0603) for high-frequency noise bypass. Minimize the power and ground via inductance by using short, wide traces or multiple vias. The land pattern should follow the IPC-7351 nominal 0805 pad dimensions of approximately 1.2 mm x 0.9 mm pad size with 0.5 mm gap.
Avoid placing the CL21A106KOQNNNE directly under tall components or near board edges where mechanical stress can cause ceramic crack failures. The 0805 ceramic is moderately robust but can still crack under board flexure exceeding 5 mm bend radius. For high-vibration or flexible-PCB applications, consider using a smaller package or adding mechanical support. The Ni-barrier + Sn plating accepts standard lead-free reflow profiles up to 260C peak per JEDEC J-STD-020.
The CL21A106KOQNNNE has a maximum operating temperature of 85C for rated performance, but the X5R dielectric itself is rated for -55C to +85C with ±15% capacitance variation. Above 85C, capacitance drops sharply and the part may be damaged. For applications approaching 125C ambient, consider an X7R alternative like the Murata GRM21AR71C106KE01L which is rated to 125C. Ripple current heating is generally not a concern for 0805 10uF MLCCs at typical switching frequencies.
Compliance Information
RoHS and REACH compliant per Samsung Electro-Mechanics product page and DigiKey compliance data. Ni-barrier + Sn lead-free terminations support 260C peak reflow per JEDEC J-STD-020. Not AEC-Q200 qualified - for automotive applications, choose AEC-Q200 qualified equivalents.
