CL31B106KAHNNNE Overview
What is a MLCC? A multilayer ceramic capacitor (MLCC) is a surface-mount passive component constructed by stacking alternating layers of ceramic dielectric and metal electrodes, then co-firing the assembly into a monolithic block. MLCCs are the dominant capacitor technology in modern electronics because they offer small size, low equivalent series resistance (ESR), high ripple current capability, and excellent high-frequency performance. Within the MLCC family, X7R is a Class II dielectric (defined by EIA RS-198) with stable capacitance across -55C to +125C and plus or minus 15 percent capacitance change over the operating temperature range, making X7R the workhorse choice for general-purpose bypass, decoupling, and filtering where X5R stability is sufficient and C0G/NP0 precision is not required.
Key specifications include 10 uF nominal capacitance at 1 kHz and 1 Vrms, 25 V rated DC working voltage, plus or minus 10 percent tolerance, X7R temperature characteristic (EIA code), 1206 (3216 metric) EIA case size, 1.6 mm x 3.2 mm x 0.95 mm typical dimensions, nickel-barrier tin-plated terminations suitable for reflow soldering, and compliance with RoHS3 and REACH. The device is rated for an operating temperature range of -55C to +125C and meets MSL 1 (unlimited floor life) per JEDEC J-STD-020, allowing direct reflow without pre-bake.
The CL31B106KAHNNNE is built on Samsung's class-leading high-CV MLCC platform, which uses fine-grained barium-titanate-based ceramic powders and controlled-thickness dielectric layers to achieve high volumetric efficiency. Internal electrode design follows a base-metal-electrode (BME) nickel inner-electrode structure co-fired in a reducing atmosphere, then terminated with a copper barrier layer and tin plating for solderability and lead-free reflow compatibility. This construction supports high inrush current handling and low ESR, which translates to effective high-frequency noise suppression on DC power rails.
Typical applications include general IC power-rail decoupling on microcontroller and SoC boards, bulk bypass capacitance on 12 V and 24 V automotive subsystems, low-side filter capacitance in switch-mode power supplies, smoothing capacitors for local point-of-load regulators, and timing/filter elements where moderate capacitance stability is sufficient. Because X7R exhibits significant capacitance loss versus DC bias and temperature, designers should derate effective capacitance in high-voltage or high-temperature regions of the design.
When designing with the CL31B106KAHNNNE, note that X7R capacitance drops as applied DC bias approaches the rated voltage; consult the manufacturer's DC-bias characteristic curves to verify effective capacitance at the operating rail voltage. For sensitive analog filter or sample-and-hold nodes, prefer C0G/NP0 dielectrics where capacitance must remain stable with bias and temperature.

Typical Applications
CL31B106KAHNNNE is suitable for 6 applications: 12V Automotive ECU Power-Rail Decoupling, Point-of-Load (POL) Regulator Output Filtering, Industrial PLC and Factory Automation Decoupling, Switch-Mode Power Supply (SMPS) Output Filter, USB and Communication Port Bypass, LED Driver Output Smoothing.
12V Automotive ECU Power-Rail Decoupling
The CL31B106KAHNNNE is well-matched to 12V automotive ECU power-rail decoupling because its 10uF bulk capacitance and 25V rating provide ample headroom over typical 13.8V running voltage with margin for load-dump transients. The 1206 footprint supports 1A+ ripple current handling, and Samsung's AEC-Q200 qualification makes it suitable for under-hood and cabin electronics. Place the part adjacent to IC power pins with a 0.1uF X7R or C0G bypass in parallel for broadband noise suppression.
Recommended
Point-of-Load (POL) Regulator Output Filtering
The CL31B106KAHNNNE provides effective output smoothing when placed downstream of a 5V or 3.3V point-of-load buck regulator. The 10uF X7R capacitance combined with low ESR reduces output ripple to under 10mV peak-to-peak in most 1A POL designs. Its 25V rating far exceeds typical POL output voltages, so DC-bias derating is mild and effective capacitance remains above 6uF across the operating range. Place directly at the POL output pin with a 1uF ceramic in parallel for high-frequency load-step response.
Recommended
Industrial PLC and Factory Automation Decoupling
The CL31B106KAHNNNE suits industrial 24V PLC and factory-automation power-rail decoupling due to its 25V rating with adequate margin over 24V nominal bus voltage, plus extended -55C to +125C operating range covering most factory environments. The 1206 footprint is industry-standard and second-sourced across multiple suppliers, supporting long-life industrial programs. Pair with TVS protection on the input side to handle inductive kickback from solenoids and motor starters.
Recommended
Switch-Mode Power Supply (SMPS) Output Filter
The CL31B106KAHNNNE functions as a low-ESR output filter in 12V-to-5V or 24V-to-5V buck converters, supporting up to 1A of ripple current at switching frequencies of 100kHz to 1MHz. The X7R dielectric's stable behavior across temperature ensures consistent output filtering in industrial SMPS designs. Combine with a small 0.1uF C0G capacitor in parallel to suppress switching-node ringing and high-frequency EMI.
Recommended
USB and Communication Port Bypass
The CL31B106KAHNNNE delivers bulk capacitance for USB 2.0/3.0 VBUS rails and RS-232/RS-485 transceiver supplies, where 10uF bulk capacitance is required for hot-plug inrush and ESD recovery. Its 1206 size handles the typical USB 1.5A peak current requirement with low voltage drop. Place near the connector-side power pin with a 0.01uF X7R in parallel to filter common-mode EMI from the data pair.
Recommended
LED Driver Output Smoothing
The CL31B106KAHNNNE serves as an effective output smoothing capacitor in constant-current LED driver circuits, where the 10uF bulk capacitance reduces LED current ripple to under 5% in most PWM-dimming designs. Its 25V rating supports LED strings up to 5 series-connected high-brightness LEDs at 24V bus voltage. Place across the LED string output with a small inductor in series for LC low-pass filtering of PWM harmonics.

Key Differentiators
- Samsung high-CV 1206 platform with AEC-Q200 qualification (vs Murata GRM31CR71E106KA12L)
- Drop-in compatibility with TDK C3216X7R1E106K160AC on the same land pattern (vs TDK C3216X7R1E106K160AC)

Design Notes
Place the CL31B106KAHNNNE as close as possible to the IC power pin it is decoupling, keeping the trace loop area under 0.5 square inches. Use two vias on each land pad to the inner power plane for low-impedance connection, and add a 0.1 uF X7R or C0G bypass capacitor in parallel for broadband noise suppression from DC to 100 MHz. Avoid placing the part directly under switching-node traces to minimize coupling.
X7R MLCCs lose effective capacitance as applied DC voltage approaches the rated voltage. For the CL31B106KAHNNNE at 12 V rail, effective capacitance may drop from 10 uF nominal to roughly 5 uF in-circuit. For tight-tolerance analog filters, derive the design value from the manufacturer's DC-bias characteristic curves rather than the nominal 10 uF rating. Capacitance also varies with temperature, dropping up to 15% at the extremes.
Although MLCCs do not dissipate significant power, reflow soldering requires controlled thermal profiles to prevent thermal-shock cracking. Use a preheat ramp of 1 to 3 C/sec, soak at 150 to 200 C for 60 to 120 seconds, and peak at 235 to 260 C for under 30 seconds. Boards over 1.6 mm thick may require longer soak times. Verify the MSL 1 classification means no pre-bake is required before reflow, simplifying assembly.
