GCM155R71H104KE02D Overview
An X7R MLCC is a Class II multilayer ceramic capacitor whose barium-titanate-based dielectric provides moderate-to-high volumetric efficiency and stable capacitance over a wide temperature range. Capacitors like the GCM155R71H104KE02D belong to the broader taxonomy: capacitor -> ceramic capacitor -> MLCC -> Class II MLCC -> X7R MLCC -> automotive-grade X7R MLCC. They occupy the engineering middle ground between low-K NP0/C0G parts (zero temperature coefficient, low volumetric density) and Class III Y5V/Z5U parts (high density but poor temperature and DC-bias stability).
Key features include a 0402 EIA case (1.0 × 0.5 mm) for high-density PCB layouts, 50 VDC rated voltage with X7R ±15% TC across -55 °C to +125 °C, ±10% capacitance tolerance, and compliance with AEC-Q200 stress-test requirements for automotive electronics. The X7R dielectric delivers high ripple-current capability and low ESR at switching frequencies, supporting bulk decoupling on 12 V automotive rails and IC supply pins.
The GCM series uses nickel-barrier terminations with 100% matte-tin plating for excellent solderability and resistance to leaching during reflow. The internal electrode is nickel, the standard for cost-effective X7R parts. The construction is qualified for lead-free reflow at peak 260 °C, matching the JEDEC J-STD-020 reflow profile used throughout the industry.
Typical applications include decoupling of 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 control, factory automation, and consumer power-conversion modules also adopt this part for its compactness and automotive-grade reliability.
When designing with this part, choose 0402 to maximize PCB density but respect the 0.5 mm pad-to-pad creepage by using 0.2-0.3 mm solder land extensions. For DC-bias derating on 50 V X7R parts, expect -15% to -50% capacitance drop at 12-25 V applied DC; for noise-sensitive analog stages where DC bias and temperature stability are critical, consider NP0/C0G alternatives.

Typical Applications
GCM155R71H104KE02D is suitable for 6 applications: Automotive ECU Microcontroller Decoupling, CAN/LIN/FlexRay Transceiver Bypass, ADAS Camera and Radar Power Conditioning, Industrial PLC 24V Rail Filtering, DC-DC Converter Output Filter, Sensor Module Signal Conditioning Bypass.
Automotive ECU Microcontroller Decoupling
The GCM155R71H104KE02D is positioned adjacent to automotive ECU microcontroller power pins to suppress high-frequency switching noise on the 3.3 V or 5 V supply rail. With 0.1 µF capacitance and X7R ±15% stability across -55 °C to +125 °C, it provides a stable local charge reservoir for MCU core transients. The 0402 (1.0 × 0.5 mm) footprint allows placement within 1-2 mm of the IC supply pin, minimizing parasitic inductance. AEC-Q200 qualification ensures reliability under under-hood thermal cycling and vibration stress.
Recommended
CAN/LIN/FlexRay Transceiver Bypass
In automotive network transceivers, the GCM155R71H104KE02D provides bulk bypass capacitance at the VCC and VIO pins of CAN, LIN, and FlexRay transceiver ICs. The 50 VDC rating provides comfortable margin over 12 V battery transients including 24 V jump-start events on heavy-duty trucks. X7R dielectric maintains stable capacitance across the -40 °C to +85 °C cabin operating range, ensuring reliable bit-timing on the bus. The 0402 footprint supports dense multi-channel transceiver layouts.
Recommended
ADAS Camera and Radar Power Conditioning
For ADAS forward-facing camera and 77 GHz radar modules, the GCM155R71H104KE02D decouples low-voltage LDO outputs powering image sensor and DSP supply rails. The ultra-small 0402 footprint enables high-density placement directly at the IC supply pin, critical for suppressing MHz-band noise that would otherwise couple into the analog front-end. AEC-Q200 grade ensures reliability across the full automotive temperature range. X7R ±15% stability prevents filter cutoff drift in RC anti-aliasing filters feeding the ADC.
Recommended
Industrial PLC 24V Rail Filtering
In industrial PLC and factory-automation modules, the GCM155R71H104KE02D filters 24 V industrial bus rails and provides local bypass for 5 V and 3.3 V logic rails derived from switching converters. The 50 VDC rating exceeds the 24 V nominal rail plus transient headroom. Although targeted at automotive, the AEC-Q200 qualification provides extra reliability margin in 24 V industrial environments with sustained high ambient temperature near motors and contactors.
Recommended
DC-DC Converter Output Filter
The GCM155R71H104KE02D serves as a low-ESR output filter on switching DC-DC converter modules in automotive infotainment and telematics. Placed at the SW node or output capacitor bank, it absorbs high-frequency ripple from buck or boost converters operating at 500 kHz to 2 MHz. The X7R dielectric handles the AC ripple current without significant self-heating, and the 50 V rating supports point-of-load converters stepping down from 12 V or 24 V intermediate buses.
Recommended
Sensor Module Signal Conditioning Bypass
In automotive and industrial sensor modules (pressure, temperature, position), the GCM155R71H104KE02D bypasses the supply pin of op-amps, references, and ADC front-ends used in signal conditioning chains. The X7R ±15% temperature stability prevents gain-stage drift across the -40 °C to +125 °C operating range. The 0402 case allows tight placement next to small sensor ASICs and op-amps in space-constrained sensor housings.

Key Differentiators

Design Notes
For the 0402 (1005 metric) GCM155R71H104KE02D, recommended land pattern dimensions per IPC-7351 are approximately 0.5 mm pad width × 0.6 mm pad length with 0.4 mm pad-to-pad spacing. Use solder mask defined (SMD) pads for tighter tolerance. Place the capacitor within 1-2 mm of the IC supply pin to minimize parasitic inductance on the high-frequency current path. For high-current transient applications, place two GCM155R71H104KE02D in parallel at slightly offset positions to share thermal stress.
Estimated: at 25 VDC applied (50% of rated), the GCM155R71H104KE02D will lose approximately 30-50% of its nominal 100 nF capacitance due to X7R Class II DC-bias derating. For analog filter or sample-and-hold applications requiring flat capacitance across voltage, use an NP0/C0G dielectric or stay below 10% of rated voltage. Do not assume the marked 100 nF is the effective capacitance at the operating bias - always derate or measure.
Although MLCCs are not typically considered heat-generating components, the GCM155R71H104KE02D will self-heat slightly when carrying AC ripple current above ~100 mA RMS. In high-ripple automotive 12 V input filter applications, ensure the capacitor stays below its self-heating limit (typically 20 °C rise). The matte-tin termination provides excellent solder joint reliability but should not be exposed to sustained temperatures above 260 °C per JEDEC J-STD-020 reflow profile.
Compliance Information
RoHS compliant per Murata product page. AEC-Q200 qualified (not AEC-Q100 - that applies to ICs). Lead-free reflow compatible to 260 °C peak per JEDEC J-STD-020.
