GRM21BR60J476ME15L Visão geral
Background Knowledge: A multilayer ceramic capacitor (MLCC) is a passive surface-mount component formed by stacking alternating thin ceramic dielectric layers and metal electrodes, then sintering them into a monolithic block with terminations on two opposing ends. MLCCs are categorized by dielectric class: Class I dielectrics (C0G/NP0) offer high stability and ultra-low loss for resonant circuits; Class II dielectrics (X5R, X7R, Y5V) offer much higher volumetric capacitance density at the cost of temperature and voltage coefficient. The 0805 case size (2.0 mm x 1.25 mm) is one of the most widely used SMD footprints, sitting in the standard mid-range between small 0402/0603 bypass caps and larger 1206/1210 bulk-decoupling caps.
Key features of the GRM21BR60J476ME15L include 47 uF nominal capacitance, 6.3 V DC rated voltage, +/-20% tolerance, X5R temperature characteristic (EIA standard), 0805 EIA / 2012 Metric case, nickel-barrier with tin (Sn) plated terminations for lead-free reflow, and compliance with RoHS directives. The X5R dielectric allows substantially higher capacitance per unit volume than X7R or C0G at the same footprint, which is critical when board real estate is constrained.
Technical depth: At 6.3 V the rated dielectric withstand voltage per Mil/Murata reliability testing is conservative, leaving margin for typical 3.3 V and 5 V rail decoupling. The X5R dielectric shows capacitance roll-off versus DC bias; engineers should consult the manufacturer datasheet's DC bias curves for the actual effective capacitance at the operating voltage. ESR for ESR in the low-milliohm range at high frequency makes the part suitable for high-frequency decoupling of processor and ASIC power pins. The 0805 footprint supports reflow soldering at standard JEDEC J-STD-020 lead-free profiles.
Typical applications include bulk decoupling of 3.3 V and 5 V IC power rails, high-frequency bypass for digital processors and ASICs, smoothing on LDO regulator outputs, coupling in audio signal paths, and general-purpose filtering in consumer, industrial, and computing equipment where high capacitance density in a small footprint is required.
When designing with this part, derate voltage by at least 30% for reliable long-term operation, account for DC-bias capacitance loss (X5R typically loses 30-60% of nominal value under rated DC voltage), and ensure the PCB land pattern follows IPC-7351 nominal 0805 pad dimensions. Always verify the lot's actual measured capacitance against design assumptions for noise-sensitive analog designs.

Aplicações típicas
GRM21BR60J476ME15L é adequado para 6 aplicaçãos: Bulk Decoupling for 3.3V/5V IC Power Rails, High-Frequency Bypass for Digital Processors, LDO Output Smoothing, Consumer Electronics Power Decoupling, USB and Power Interface Filtering, Industrial Control and Embedded Systems.
Bulk Decoupling for 3.3V/5V IC Power Rails
The GRM21BR60J476ME15L provides 47 uF of bulk capacitance for 3.3 V and 5 V IC power rails where high volumetric capacitance density is required in compact PCB layouts. According to Murata's GRM series datasheet, the X5R dielectric delivers high capacitance per unit volume, making it ideal for placing adjacent to processor and ASIC power pins where 0402/0603 capacitors would lack sufficient charge storage. The 0805 footprint fits standard IPC-7351 land patterns while delivering roughly 10x the capacitance of comparably sized X7R parts. Engineers typically place one or more of these capacitors at each major power pin of FPGAs, microcontrollers, and SoCs to reduce voltage droop during high di/dt load transients.
Recomendado
High-Frequency Bypass for Digital Processors
The GRM21BR60J476ME15L serves as a high-frequency bypass capacitor for digital processors, FPGAs, and ASICs operating at 3.3 V or below. The X5R dielectric provides low ESR in the low-milliohm range at frequencies from 100 kHz to 10 MHz, effectively shunting switching noise to ground. According to standard decoupling design practice, multiple GRM21BR60J476ME15L capacitors are placed near each power pin alongside smaller 0.1 uF X7R bypass caps that handle the higher-frequency noise spectrum above 10 MHz. The 0805 footprint provides sufficient thermal dissipation for reflow soldering at JEDEC J-STD-020 lead-free profiles without tombstoning.
Recomendado
LDO Output Smoothing
The GRM21BR60J476ME15L is commonly used on the output of low-dropout (LDO) regulators to improve load transient response and reduce output ripple. According to LDO datasheet recommendations, an output capacitor with low ESR and stable capacitance across the operating voltage range is required for regulator stability. The X5R dielectric of this part maintains adequate capacitance at 3.3 V output, and the 6.3 V rating provides headroom above typical 5 V or 3.3 V LDO outputs. The 47 uF capacitance is large enough to suppress load-step transients in the tens-of-milliamps range common in microcontroller power trees.
Recomendado
Consumer Electronics Power Decoupling
The GRM21BR60J476ME15L is widely deployed in consumer electronics including smartphones, tablets, wearables, Bluetooth audio devices, and IoT products where board space is at a premium. The 0805 footprint delivers 47 uF in a 2.5 mm^2 footprint, enabling high-density power decoupling without sacrificing capacitance. According to Murata's GRM series documentation, this part is qualified to AEC-Q200 for automotive-grade reliability, making it suitable for both consumer and automotive applications. Distributors stock this part in volume reels (4000 pcs/reel typical), enabling high-throughput SMT assembly lines common in consumer electronics manufacturing.
Recomendado
USB and Power Interface Filtering
The GRM21BR60J476ME15L provides bulk filtering at USB power (VBUS) lines, battery charging circuits, and other 5V-tolerant power interfaces. The 6.3 V rated voltage provides margin above the 5 V USB VBUS rail, and the 47 uF capacitance effectively suppresses power-line noise from upstream switching converters. According to USB 2.0/3.0 power delivery design guidelines, bulk capacitors at the device VBUS pin reduce voltage ripple during current transients. The X5R dielectric's DC-bias characteristics should be considered - at 5 V the effective capacitance may drop to approximately 30-35 uF.
Recomendado
Industrial Control and Embedded Systems
The GRM21BR60J476ME15L is specified in embedded industrial control systems, PLCs, motor controllers, and sensor interface modules where 3.3 V or 5 V digital logic requires reliable bulk decoupling. According to Murata's GRM series datasheet, the part operates over the full -55C to +85C industrial temperature range with X5R's +/-15% capacitance variation. The nickel-barrier tin-plated terminations provide excellent solderability and long-term reliability in industrial environments. Designers typically place one GRM21BR60J476ME15L per major IC power pin alongside smaller 0.1 uF capacitors to cover both bulk energy storage and high-frequency noise rejection.

Notas de projeto
Estimated: X5R dielectric capacitance drops significantly under DC bias. At the rated 6.3 V, a 47 uF GRM21BR60J476ME15L may deliver only 30-40 uF of effective capacitance; at 3.3 V the effective value is approximately 38-42 uF. For designs requiring guaranteed minimum capacitance (e.g., hold-up time, regulator stability), consult the Murata DC bias curves and either derate the design or select the GRM21BR61A476ME15L 10 V variant for more stable capacitance under typical operating voltages.
Use IPC-7351 nominal 0805 land pads (approximately 1.0 mm x 1.5 mm per pad with 0.5 mm spacing) for the GRM21BR60J476ME15L. Place the capacitor as close as possible to the IC power pin, with wide traces to minimize parasitic inductance. For high-frequency decoupling above 10 MHz, place a 0.1 uF X7R (e.g., 0402) capacitor in parallel with the GRM21BR60J476ME15L to cover the higher frequency noise spectrum.
The GRM21BR60J476ME15L is rated for standard reflow soldering at JEDEC J-STD-020 lead-free profiles (peak 260C for up to 30 seconds). The nickel-barrier tin-plated terminations provide excellent solderability and long-term reliability. MSL Level 1 means unlimited floor life at <=30C/85% RH, simplifying inventory and PCB assembly handling. Avoid manual soldering with excessive heat that may damage the X5R dielectric or cause thermal cracking of the ceramic body.
