GCM155R71H104KE02D Visão geral
A multilayer ceramic capacitor (MLCC) is a passive two-terminal component that stores energy in an electrostatic field between alternating layers of metal electrodes and ceramic dielectric. In the broader taxonomy this part sits at: capacitor → ceramic capacitor → MLCC → Class II MLCC → X7R → automotive-grade X7R. X7R occupies the engineering middle ground between low-K NP0/C0G parts (zero temperature coefficient, lower volumetric density) and high-K Y5V/Z5U parts (high density but poor temperature and DC-bias stability), which is why X7R is the default dielectric for general-purpose bypass, decoupling, and filtering networks across consumer, industrial, and automotive segments.
Key features include the EIA 0402 footprint for sub-0.5 mm pad-pitch layouts, 50 V working voltage, ±10% capacitance tolerance at 25 °C, full AEC-Q200 stress-test qualification for automotive reliability, MSL-1 unlimited floor life, and 7-inch paper-tape packaging per EIA 481 for high-speed SMT placement. The 0402 case enables pad pitches down to 0.5 mm and is the de facto high-density land pattern for bypass networks on modern microcontrollers, SoCs, and CAN/LIN transceivers.
Architecturally, the GCM155R71H104KE02D uses stacked barium-titanate-based ceramic layers with screen-printed nickel electrodes co-fired into a monolithic body, then terminated with a nickel-barrier under-layer and matte-tin finish for solderability. The Class II X7R designation reflects a mid-K dielectric whose capacitance is moderate-to-high per unit volume but exhibits predictable DC-bias derating and a modest temperature coefficient (±15% across -55 °C to +125 °C), which engineers must budget for in precision analog filters or timing networks.
Typical applications include decoupling automotive ECU microcontrollers, bypassing sensors and CAN/LIN/FlexRay transceivers, ADAS camera and radar power conditioning, and general-purpose filtering on 5 V, 12 V, and 24 V rails. Industrial controllers and factory-automation modules adopt it for compactness and the AEC-Q200 reliability pedigree.
When designing with this part, choose 0402 to maximize PCB density but respect 0.5 mm pad-to-pad creepage using 0.2–0.3 mm solder-land extensions. Expect measurable DC-bias derating on X7R parts: applied DC bias of 12–25 V can reduce effective capacitance by 15–50% depending on dielectric lot.
This page synthesizes distributor pricing, AEC-Q200 qualification context, drop-in 0402 X7R alternatives, and practical PCB layout notes that go beyond the manufacturer datasheet summary, giving engineers a single reference for sourcing, substitution, and design validation.

Aplicações típicas
GCM155R71H104KE02D é adequado para 7 aplicaçãos: Automotive ECU Decoupling, ADAS Camera & Radar Power Conditioning, CAN / LIN / FlexRay Transceiver Filtering, Industrial PLC & Factory Automation, High-Density BGA Breakout Bypass, 5 V / 12 V / 24 V General-Purpose Filtering, Consumer Electronics Power Decoupling.
Automotive ECU Decoupling
The GCM155R71H104KE02D is the de facto bypass capacitor for automotive ECU microcontroller power pins. Its 0.1 µF / 50 V rating and 0402 (1.0 × 0.5 mm) footprint allow placement directly beneath the BGA breakout of modern 32-bit automotive MCUs (NXP S32K, Infineon Aurix, TI Hercules), where the AEC-Q200 qualification guarantees survival under bias-humidity and 1500-hour thermal-shock stress. The X7R dielectric delivers ~50 nF effective capacitance at 25 V applied DC bias (typical 5 V and 12 V automotive rails), which is sufficient for high-frequency decoupling above 10 MHz. Compared with Y5V or Z5U alternatives, the X7R ±15% capacitance tolerance over -55 °C to +125 °C gives stable decoupling across underhood temperature swings.
Recomendado
ADAS Camera & Radar Power Conditioning
ADAS sensor modules (front-camera, surround-view, 77 GHz radar) demand AEC-Q200 qualified bypass networks on 5 V and 12 V rails where failure is not an option. The GCM155R71H104KE02D provides 100 nF at 50 V rating in a 0402 case small enough to fit behind fine-pitch sensor connectors and BGA image-sensor breakouts. The matte-tin-over-nickel termination resists thermal-shock solder-joint fatigue, and MSL-1 unlimited floor life simplifies high-mix SMT production. When designing ADAS power, place one GCM155R71H104KE02D per sensor power pin plus a 10 µF bulk on the rail input.
Recomendado
CAN / LIN / FlexRay Transceiver Filtering
Automotive in-vehicle networking transceivers (CAN-FD, LIN, FlexRay) require 100 nF bypass on VCC and VIO pins to suppress bus-side switching transients that couple back into the supply rail. The GCM155R71H104KE02D's 50 V rating and X7R dielectric make it ideal for 12 V and 24 V battery rails where load-dump can spike to 35 V. The 0402 footprint enables placement immediately adjacent to transceiver SOIC-8 pins without extending trace length beyond 1 mm, preserving noise immunity on the bus. AEC-Q200 stress-test qualification is mandatory for OEM EMC and ESD compliance in production vehicles.
Recomendado
Industrial PLC & Factory Automation
Industrial PLCs, motor drives, and factory-automation I/O modules adopt the GCM155R71H104KE02D because its AEC-Q200 qualification exceeds typical IEC 61010 industrial requirements while the 0402 case enables compact DIN-rail designs. The 50 VDC rating covers 24 V industrial bus transients, and the -55 °C to +125 °C operating temperature handles outdoor cabinet environments. Place one GCM155R71H104KE02D per logic-isolator power pin and per 24 V sensor-input filter pole. Compared with consumer-grade GRM-series parts, the GCM series provides documented lot-traceability for regulated industries.
Recomendado
High-Density BGA Breakout Bypass
Modern SoCs and FPGAs in BGA packages with 0.5–0.8 mm pitch require 0402 bypass capacitors to fit in the breakout region between BGA balls. The GCM155R71H104KE02D's 1.0 × 0.5 mm 0402 footprint occupies less than half the area of a 0603, enabling dense VCC/VSS ball arrays to be bypassed with one capacitor per power pin. The 50 V rating and X7R dielectric provide adequate headroom on 3.3 V, 5 V, and 12 V rails commonly used on BGA-based processor boards. For best results, place the part on the opposite PCB side from the BGA with a via-in-pad for shortest loop inductance.
Recomendado
5 V / 12 V / 24 V General-Purpose Filtering
The GCM155R71H104KE02D works as a general-purpose 100 nF filter capacitor on 5 V, 12 V, and 24 V DC rails in non-critical analog and digital circuits where AEC-Q200 reliability pedigree is desired even when automotive certification is not strictly required. The 50 VDC rating provides a 2× safety margin on 24 V rails, and the ±10% tolerance is acceptable for RC low-pass filters, snubber networks, and DC-bias blocks. Designers should remember X7R DC-bias derating: applied 25 V on a 50 V-rated part can drop effective capacitance by ~30–50%, so verify with manufacturer curves.
Recomendado
Consumer Electronics Power Decoupling
Although qualified for automotive, the GCM155R71H104KE02D is equally suitable for high-end consumer electronics (smartphones, tablets, wearables, AR/VR headsets) where small footprint, AEC-Q200 reliability pedigree, and consistent lot-to-lot performance are valued. The 0402 case fits in the 0.5 mm-pitch breakout of sub-7 mm × 7 mm PMICs and SoCs. The MSL-1 unlimited floor life simplifies high-volume pick-and-place, and the matte-tin termination is compatible with lead-free SAC305 reflow profiles. For cost-sensitive designs, the GRM155R71H104KE14D provides the same 0402 X7R 100 nF 50 V without automotive qualification.

Notas de projeto
X7R capacitors exhibit significant DC-bias derating: applied DC voltage can reduce effective capacitance by 30–50% on a 0402 100 nF 50 V part. For a 24 V rail on a 50 V rated GCM155R71H104KE02D, expect roughly 50–70 nF effective capacitance at 25 °C. Always consult the manufacturer's DC-bias characteristics chart (not a single capacitance number) when designing RC filters or timing networks; budget the derated value to ensure worst-case performance.
For 0402 footprint design, use a solder-land extension of 0.2–0.3 mm beyond the nominal pad (per IPC-7351 nominal land pattern) to ensure adequate solder fillet and tombstone prevention. Maintain a minimum 0.5 mm pad-to-pad pitch to avoid solder bridging, and place the GCM155R71H104KE02D within 1 mm of the IC power pin with a via-in-pad when used as a BGA-breakout bypass. Avoid routing high-speed traces between the two pads as this distorts the ESL and degrades decoupling effectiveness above 100 MHz.
When using the GCM155R71H104KE02D for high-frequency decoupling, minimize the current-loop area by placing the part directly across the power pin and ground via, with the ground via placed closer to the GND pad than the power pad. For BGA-breakout layouts, use a 0.2 mm-diameter microvia-in-pad on the power pin and route the ground pad to an adjacent ground ball via. This reduces ESL to ~0.5 nH, achieving effective decoupling up to ~200 MHz. For rails above 1 MHz switching, complement the GCM155R71H104KE02D with a 1 µF or 10 µF bulk (e.g., GRM188R71C105KA12D) to cover the mid-frequency band.
