CL21B472KCANNNC 개요
A multilayer ceramic capacitor (MLCC) is a passive component constructed by stacking alternating metal electrode layers and ceramic dielectric layers, then sintering them into a monolithic block. MLCCs are the dominant capacitor technology in modern electronics because they offer small size, low ESR, excellent high-frequency performance, and high reliability at low cost. X7R is a Class II dielectric - the second-most-stable MLCC family - trading absolute precision for high volumetric efficiency and moderate temperature stability, which suits applications like decoupling, snubbing, and AC coupling where exact capacitance value is not critical.
Key features of the CL21B472KCANNNC include a 100 V rated DC working voltage, ±10% capacitance tolerance, X7R temperature characteristic (EIA code), Ni-barrier + matte tin finish compatible with lead-free reflow soldering up to 260 °C peak (10 s max), and compliance with RoHS/REACH directives. The 0805 (2012 Metric) case measures 2.00 × 1.25 mm land pattern and is one of the most widely adopted SMD capacitor footprints.
The CL21B472KCANNNC uses a nickel inner electrode (BME) construction with nickel-barrier terminations to prevent silver migration and ensure solderability after long storage. The matte-tin outer layer prevents tin-whisker growth, an important reliability factor for automotive and long-lifecycle products.
Typical applications include general-purpose bypass/decoupling on 5 V, 12 V, and 24 V analog/digital rails, R-C timing networks in oscillators and filters, snubbing across switching-node parasitic inductances, AC coupling in audio signal paths, and energy storage in low-power DC-DC converters. Its 100 V rating provides ample headroom above typical 12 V or 24 V bus rails.
When designing with this part, observe the published derating curve (typically 50% of rated voltage for Class II dielectrics) and confirm mechanical pad dimensions match the 0805 land pattern. For high-ripple or high-frequency decoupling, consider paralleling multiple capacitors of different values to broaden the impedance profile.

일반적인 애플리케이션
CL21B472KCANNNC 적합 용도: 6 애플리케이션s: General-Purpose Bypass / Decoupling on 12V and 24V Rails, R-C Timing and Filter Networks, Snubber Across Switching-Node Parasitics, AC Coupling in Audio Signal Paths, Energy Storage in Low-Power DC-DC Converters, Industrial Sensor Signal Filtering.
General-Purpose Bypass / Decoupling on 12V and 24V Rails
The CL21B472KCANNNC is well-suited to general-purpose bypass and decoupling on 12 V and 24 V power rails in industrial, automotive, and consumer electronics. With 100 V rated DC working voltage (50% above the 24 V bus) and X7R dielectric maintaining ±15% capacitance across -55 °C to +125 °C, it cleanly absorbs switching transients without breakdown. Placed in parallel with smaller (e.g. 100 nF) and larger (e.g. 10 µF) capacitors, the 4.7 nF X7R fills the mid-frequency impedance notch, where bulk electrolytics lose effectiveness and tiny ceramics self-resonate. Trade-off: X7R exhibits ±15% DC-bias capacitance loss, so verify effective C under the actual rail voltage in your design.

R-C Timing and Filter Networks
The CL21B472KCANNNC's 4.7 nF ±10% capacitance and stable X7R dielectric make it a reliable choice for R-C low-pass filters, high-pass filters, and oscillator timing circuits. With a 10 kΩ series resistor it forms a 3.4 kHz single-pole low-pass filter; with 1 kΩ it shifts the corner to 34 kHz. The 100 V rating provides ample headroom for signal swings in line drivers, audio preamp coupling, and sensor signal conditioning. The X7R dielectric's ±15% tolerance over temperature is acceptable for non-precision timing, but for oscillators requiring better than ±5% frequency stability, C0G/NP0 capacitors should be substituted. Pair this part with a 1% metal-film resistor for predictable corner frequencies.

Snubber Across Switching-Node Parasitics
In switching converter and motor-drive circuits, the CL21B472KCANNNC serves as an effective R-C snubber across switching-node parasitic inductances. The 4.7 nF value is a typical snubber capacitance for small MOSFET half-bridges operating at 24-48 V, and the 100 V rating gives generous margin above typical 48 V bus transients. X7R dielectric is adequate here because the snubber sees AC voltage at switching frequency rather than DC bias - so DC-bias capacitance loss is irrelevant. This part will damp voltage spikes that would otherwise exceed the MOSFET's VDS rating. Combine with a low-inductance resistor to keep the snubber loop area small.

AC Coupling in Audio Signal Paths
The CL21B472KCANNNC's X7R dielectric and 100 V rating suit AC-coupling positions in audio signal paths - particularly coupling between op-amp stages, in/out coupling for line-level audio interfaces, and as part of passive equalizer networks. With a 4.7 nF coupling cap and a 10 kΩ input impedance, the high-pass corner is around 3.4 kHz, which is appropriate for AC-coupling audio blocks but cuts sub-bass. The X7R ±15% tolerance is acceptable for AC-coupled audio since absolute cutoff accuracy is rarely critical. The 100 V rating also lets it survive line-voltage transients in audio interfaces that see ESD or hot-plug events. For highest-fidelity audio paths, C0G/NP0 is preferred.

Energy Storage in Low-Power DC-DC Converters
The CL21B472KCANNNC can serve as energy-storage capacitance in low-power DC-DC converters, particularly as a flying or flying-reservoir capacitor in charge-pump topologies or as a soft-start capacitor in switching regulators. The 4.7 nF is appropriate for low-current charge pumps driving LED bias or analog rails. The 100 V rating handles the stacked-output voltage of multi-stage charge pumps. X7R's volumetric efficiency (vs C0G) makes this part cost-effective at the 0805 size, and the Ni-barrier + matte-tin termination supports the high thermal-cycling stresses of DC-DC service. For switch-node positions, verify derating against peak Vpk.
추천
Industrial Sensor Signal Filtering
The CL21B472KCANNNC works as a low-pass filter capacitor on industrial sensor signal lines, particularly for 4-20 mA current-loop receivers, RTD/thermocouple signal conditioning, and proximity-sensor outputs. With a 4.7 nF cap across a high-impedance sensor input, the noise bandwidth is limited to frequencies well below the sensor's signal bandwidth, improving EMC immunity. The wide -55 °C to +125 °C operating envelope covers outdoor and industrial cabinet environments. The 100 V rating also provides significant margin against the induced transients on long sensor cable runs in factory automation. X7R dielectric is appropriate here because absolute capacitance is not critical - just filtering of out-of-band noise.

설계 노트
Follow the standard 0805 land pattern per IPC-7351: two rectangular pads of 1.0-1.2 mm length × 0.9-1.0 mm width on a 2.5 mm center-to-center pitch. Place the capacitor as close as possible to the IC pin or noise source to minimize parasitic loop inductance. For high-frequency decoupling, also consider via-in-pad construction to reduce via inductance, and avoid long trace stubs between the cap and the power rail.
Apply the standard Class II derating of 50% of rated DC voltage for reliability - i.e., target continuous working voltage ≤50 V for this 100 V part. Although the part is rated 100 V, sustained operation near that limit accelerates aging and reduces effective capacitance. For sub-50 V rails (5 V, 12 V, 24 V), the 100 V rating provides large headroom but a lower-voltage part (e.g. 50 V) is typically cheaper and acceptable. Always confirm against your actual worst-case rail voltage including transients.
X7R capacitance drops significantly under DC bias - up to -30% to -50% at rated voltage. The 4.7 nF part may effectively behave like 3.0-3.5 nF under 50 V DC bias. Do not select X7R for precision filter or oscillator applications where exact capacitance matters. Also note that capacitance drops further at the temperature extremes (-55 °C, +125 °C) and is reduced at high frequencies due to self-resonance effects around 1-10 MHz for 0805 X7R parts.
For parallel-capacitor decoupling networks, place the smallest value (4.7 nF in this case) closest to the IC and the largest value (10 µF or larger) furthest. This minimizes the high-frequency loop area and ensures the smallest cap handles the highest-frequency noise. Keep trace widths short and symmetric, and use ground pour on the opposite PCB layer directly under the capacitor for return-current path.
