An MLCC is the most widely used capacitor type in modern electronics: alternating layers of ceramic dielectric (here barium-titanate-based Class 2 X7R material) and nickel or precious-metal electrodes are co-fired into a monolithic block, terminated on opposing ends for surface mounting. Within the component hierarchy, the MLCC sits under fixed capacitor, under capacitor, and under passive electronic components. Class 2 dielectrics such as X7R offer high volumetric efficiency at the cost of some capacitance variation with voltage, temperature, and time, in exchange for compact decoupling-grade capacitance.
Key features of this part include 10 uF of capacitance in a compact 2.0 mm x 1.25 mm footprint, an X7R temperature characteristic stable from -55 degrees C to +125 degrees C with a maximum capacitance change of plus or minus 15 percent across that range, and tight plus or minus 10 percent initial tolerance. The C Series construction supports reflow soldering and standard SMT pick-and-place assembly. Typical applications documented by KEMET include decoupling, bypass, filtering, and transient voltage suppression.
Technically, the X7R dielectric provides high dielectric constant (high k), enabling Class 2 MLCCs to reach 10 uF in 0805 without stacking to larger case sizes. Like all X7R parts, its effective capacitance decreases under DC bias, so designers should derate the working voltage relative to the 10 V rating for bias-sensitive circuits such as timing networks; bulk decoupling duties are far more tolerant of this behavior.
Typical use cases include power-rail decoupling for microcontrollers and FPGAs, bypass of analog supply pins on op-amps and data converters, low-pass filter networks in power supplies, and transient voltage suppression at connector entry points in industrial and consumer equipment.
A key design consideration: place this capacitor close to the decoupled IC power pin and account for DC bias derating - at high bias fractions of the 10 V rating, delivered capacitance can fall well below the nominal 10 uF, so verify the effective value with the manufacturer DC bias curves in the KEMET datasheet.
This page adds value beyond the raw datasheet by synthesizing distributor pricing from DigiKey, Mouser, and LCSC, same-package drop-in alternatives, and practical design notes for bias derating and layout.

Tipik Uygulamalar
C0805C106K8RACTU için uygundur 6 uygulamas: Microcontroller / FPGA Power Decoupling, Analog IC Supply Bypass, DC-DC Converter Output Filtering, Transient Voltage Suppression at Connector Entry, Consumer Electronics Board-Level Decoupling, Industrial Automation Control Boards.
Microcontroller / FPGA Power Decoupling
The C0805C106K8RACTU serves as local decoupling for microcontroller and FPGA supply rails, one of the four applications KEMET documents for the C Series (decoupling, bypass, filtering, transient suppression). Its 10 uF capacitance in a compact 2.0 x 1.25 mm 0805 footprint provides bulk charge storage directly at each VDD pin group, smoothing load-transient currents that upstream regulators cannot respond to quickly. On a 3.3 V rail the DC bias consumes only a third of the 10 V rating, so effective capacitance remains close to nominal. Place one part per power pin cluster with short traces; the X7R dielectric tolerates the wide industrial -55C to +125C ambient range, though a +/-15% temperature coefficient means designers should not rely on the exact 10 uF value for anything beyond decoupling impedance targets.

Analog IC Supply Bypass
For op-amps, ADCs, and DACs, the C0805C106K8RACTU provides the 10 uF bulk bypass at analog supply pins while a nearby 100 nF C0G or X7R handles high-frequency content. KEMET lists bypass as a documented application for this part. The X7R dielectric's higher ESR relative to C0G is actually beneficial here, adding natural damping that suppresses resonance between the bypass network and regulator output impedance. On precision analog rails below 5 V, DC bias derating is minimal, so nearly the full nominal 10 uF is delivered. One trade-off: X7R's piezoelectric behavior can couple board vibration into sensitive nodes, so for ultra-low-noise references consider adding a film or tantalum capacitor in parallel rather than relying on the ceramic alone.

DC-DC Converter Output Filtering
In point-of-load buck converter outputs, the C0805C106K8RACTU contributes the bulk of output capacitance, setting output ripple and load-transient response. KEMET documents filtering as a typical C Series application. Because the X7R capacitance drops with DC bias, a converter regulating 5 V from a 10 V-rated capacitor should be derated or paralleled - many designs place two of these parts in parallel to achieve the effective capacitance the control loop compensation was designed for. The part's low ESR supports stable loops with modern current-mode controllers, but excessive low ESR combined with long input leads can cause input-rail ringing; a small series resistor or damping capacitor resolves this. Verify the effective capacitance against the DC bias curves in the KEMET specsheet before finalizing loop compensation.

Transient Voltage Suppression at Connector Entry
KEMET lists transient voltage suppression among the C Series' typical applications. At connector and cable entry points, the C0805C106K8RACTU absorbs fast, low-energy transients and ESD residual energy, working alongside TVS diodes that clamp the bulk of surge energy. The 10 uF capacitance, while lossy at high frequency compared to smaller capacitors, supplies immediate charge during burst events such as IEC-level ESD contacts on external interfaces. On industrial 24 V-adjacent signals, the 10 V rating limits this part to logic-level or divided-down lines, so apply it after regulation. For harsher environments, choose the flex-terminated C0805C106K8PACTU variant, which resists the mechanical cracking caused by connector insertion forces transmitted through the PCB.

Consumer Electronics Board-Level Decoupling
In smartphones, set-top boxes, and IoT devices, the 0805 case size balances placement density and assembly yield: smaller 0603 10 uF parts cost more and crack more easily, while 1206 wastes area. The C0805C106K8RACTU delivers the KEMET-documented decoupling and bypass functions with a tolerance of +/-10% for predictable rail behavior. LCSC pricing from $0.1951 as of 2026-09-05 makes it economical for high-volume consumer BOMs, and availability across DigiKey, Mouser, and LCSC protects against allocation. Designers should note that 3.3 V to 5 V rails bias this 10 V-rated part moderately, preserving usable capacitance, whereas applying it near the full 10 V rating in battery-pack circuits demands derating to the DC bias curve in the official KEMET specsheet.

Industrial Automation Control Boards
Industrial PLC I/O and motor-control boards face wide ambient temperatures and mechanical vibration. The C0805C106K8RACTU's -55C to +125C operating range covers industrial requirements, and its X7R dielectric maintains decoupling function across that span within the +/-15% temperature coefficient. KEMET's documented filtering role suits the RC input filtering of analog I/O channels. Because vibration and thermal cycling can crack rigid-termination MLCCs, high-vibration cabinets should favor the flex-terminated C0805C106K8PACTU on the same footprint. The 10 V rating fits the 5 V and 3.3 V logic domains of control boards but not raw 24 V field signals, which need higher-voltage-rated MLCCs or series regulation before local decoupling with this part.

Tasarım Notları
DC bias derating is the single most common mistake with 10 uF X7R MLCCs. The 10 uF figure is measured at 0 V bias; under real rail voltage the effective capacitance can drop to a fraction of nominal. For a 5 V rail on this 10 V part, consult the KEMET DC bias curves in the official specsheet and size the number of capacitors based on effective, not nominal, capacitance. This is an estimate-level design consideration, not a datasheet value - the exact derating percentage must be read from the manufacturer curves.
Place the C0805C106K8RACTU within 2-3 mm of the decoupled IC power pin with short, wide traces (0.3 mm width minimum) to minimize loop inductance. Vias to the power plane should be placed immediately adjacent to the pads, not shared as long stubs. The part reflows with standard SAC305 lead-free profiles; the 0805 case tolerates typical pick-and-place handling, but boards subject to flexing near connectors should use the flex-terminated C0805C106K8PACTU on the identical footprint instead.
Do not use this X7R part in timing networks, precision RC filters, or sample-hold circuits: the +/-15% temperature coefficient, DC bias dependence, aging drift, and piezoelectric (microphonic) behavior make it unsuitable where capacitance value accuracy matters. Reserve C0805C106K8RACTU for decoupling, bulk bypass, and suppression roles. For precision analog timing, select a C0G/NP0 dielectric at smaller capacitance or an NPO film capacitor.
