GRM21BR61A476ME15L 개요
An MLCC (Multilayer Ceramic Capacitor) is a passive component constructed by stacking alternating layers of ceramic dielectric and metal electrodes, then sintering them into a monolithic block. X5R is a Class 2 dielectric defined by EIA-198, offering stable capacitance over -55°C to +85°C with ±15% variation. Compared to Class 1 dielectrics (NP0/C0G), X5R delivers much higher volumetric efficiency, enabling the 47 µF rating in a compact 0805 footprint that would otherwise require a tantalum or electrolytic capacitor.
Key features of the GRM21BR61A476ME15L include 47 µF nominal capacitance in a 2.0 mm × 1.25 mm (0805) package, 10 V DC rated voltage, ±20% capacitance tolerance, X5R temperature characteristic, and Ni-barrier + Sn-plate terminations compatible with lead-free reflow. The component is RoHS compliant and qualified to Murata's automotive-grade reliability flow on selected lots. Its 0805 size balances high density with robust solder-joint strength, making it suitable for both hand and automated assembly.
In circuit, the GRM21BR61A476ME15L is typically used as a local decoupling capacitor near IC power pins, where it suppresses high-frequency noise and stabilizes the supply rail. The X5R dielectric's high permittivity provides bulk energy storage close to the load, reducing voltage droop during transient current demands from digital logic, microcontrollers, and RF transceivers.
Typical applications include smartphone PMIC output filtering, USB Type-C decoupling, IoT sensor modules, MCU bypass networks, wearable device power rails, and consumer audio codec supplies. Designers value the GRM series for its mature supply chain, predictable DC-bias characteristics, and global multi-source availability.
When designing with this part, account for DC-bias capacitance loss. X5R 47 µF capacitors can lose up to 70-80% of nominal capacitance under their full rated voltage, so effective capacitance at 10 V may be considerably lower than 47 µF. Always verify bias behavior from the manufacturer datasheet curves when designing timing or filter circuits sensitive to absolute capacitance.
This page synthesizes distributor pricing, drop-in alternatives from multiple manufacturers, and practical bias-aware design notes not consolidated in the Murata datasheet alone.

일반적인 애플리케이션
GRM21BR61A476ME15L 적합 용도: 6 애플리케이션s: Mobile Phone PMIC Decoupling, USB Type-C VBUS Decoupling, IoT Sensor Module Power Rails, Microcontroller Bypass Network, Wearable Device Power Decoupling, Consumer Audio Codec Supply Filtering.
Mobile Phone PMIC Decoupling
The GRM21BR61A476ME15L's 47 µF X5R capacitance in a 0805 footprint makes it ideal for bulk decoupling on smartphone power management IC (PMIC) output rails operating at 3.8 V nominal from a 4.2 V Li-ion battery. The 10 V rating provides ample margin against transient spikes while the X5R dielectric's high permittivity delivers bulk energy storage within a few millimeters of the load. Placed between the PMIC output and the SoC, the capacitor suppresses voltage droop during sudden load steps from modem, GPU, or display subsystems. The 0805 size balances PCB density with sufficient copper pad area for low parasitic inductance. For designs spanning multiple voltage rails, designers commonly place several GRM21BR61A476ME15L parts at the PMIC outputs to handle simultaneous peak currents.

USB Type-C VBUS Decoupling
USB Type-C VBUS rails operating at 5 V benefit from the GRM21BR61A476ME15L's 47 µF / 10 V rating, which provides bulk filtering between the connector VBUS pin and downstream power circuitry. The X5R dielectric handles the 5 V bias with moderate capacitance loss, while the 0805 package handles reflow-soldered production reliably. Designers commonly use it as a local decoupling cap on the VBUS-to-5 V buck converter input, suppressing line transients and ESD-induced noise spikes. The 0805 footprint is small enough to fit near the connector footprint without crowding the high-speed signal lines. For USB-PD applications demanding tighter ripple, the GRM21BR61A476ME15L is often paired with a smaller 100 nF X7R cap for high-frequency bypass.
추천
IoT Sensor Module Power Rails
Low-power IoT sensor modules frequently operate from a 3.3 V or 3.0 V rail sourced from a Li-ion battery or USB input, where the GRM21BR61A476ME15L provides effective bulk capacitance at 10 V rating with ample voltage margin. The X5R dielectric is well-suited for indoor and outdoor sensor nodes within its -55 °C to +85 °C rating. Placed on the LDO or buck output supplying the wireless MCU (e.g., BLE, LoRa, or Wi-Fi), the capacitor stabilizes the rail during RF transmit bursts that draw sudden peak currents. The 0805 size fits compact sensor modules and is preferred over 0603 for higher mechanical robustness in field-deployed sensors.
추천
Microcontroller Bypass Network
Most 32-bit microcontrollers require 100 nF-to-100 µF decoupling across their VDD pins, and the GRM21BR61A476ME15L provides the high-capacitance end of this stack. Its 47 µF bulk rating with X5R dielectric pairs naturally with smaller 100 nF NP0/C0G capacitors placed closer to each VDD pin for high-frequency noise rejection. The 0805 footprint gives engineers a balance between size and pad strength, important for designs that may be hand-reworked. Common placements include the MCU's main VDD_CORE and VDD_IO pins, where the GRM21BR61A476ME15L handles large transient currents during wake-up from sleep or peripheral activation.

Wearable Device Power Decoupling
Wearable fitness trackers and smartwatches depend on dense, low-profile power decoupling, and the GRM21BR61A476ME15L's 0805 footprint combined with 47 µF capacitance fits the bill. The 10 V rating easily covers the 3.7 V Li-ion battery rail plus margin. Designers place it on the output of the PMIC, the input of the buck-boost converter, and directly at the SoC supply pins to maintain stable voltage during high-current BLE radio bursts. The lead-free Ni-Sn termination meets all wearable RoHS requirements and survives repeated reflow cycles during module assembly. The halogen-free molding compound also satisfies IEC 61249-2-21 for skin-contact devices.

Consumer Audio Codec Supply Filtering
Consumer audio codecs and headphone amplifiers demand clean low-noise power rails, and the GRM21BR61A476ME15L's X5R dielectric provides effective bulk filtering on the 3.3 V or 5 V analog supply. Its 47 µF capacitance attenuates low-frequency ripple from upstream switching converters, while pairing with 100 nF X7R caps handles high-frequency noise. The 0805 package is small enough to fit near the codec's AVDD pin without disturbing sensitive analog signal routing. Engineers often place the GRM21BR61A476ME15L at the codec LDO output and at the headphone amplifier AVDD pin, where it provides local energy storage and reduces pop/click artifacts during audio playback startup.

설계 노트
DC-bias capacitance loss is the most common pitfall when designing with X5R 47 µF MLCCs. At the full 10 V rated voltage, the effective capacitance can drop to roughly 20-40% of nominal per the Murata datasheet bias curve. Estimated: assuming a 70% bias loss at 10 V, a '47 µF' cap behaves like 14 µF in-circuit. Always consult the manufacturer DC-bias curve and oversize the capacitance by 2-3× if the circuit depends on absolute value, such as in bulk filter or hold-up applications.
Place the GRM21BR61A476ME15L as close as practical to the IC supply pin to minimize loop inductance. Use wide copper traces (≥0.3 mm) and connect ground returns directly to the IC's GND pad via a short via or direct copper path. Pair it with a 100 nF X7R/NP0 capacitor within 1-2 mm of the IC for high-frequency decoupling. The 0805 footprint tolerates hand-soldering and standard reflow profiles up to 260 °C peak per J-STD-020.
Avoid using a single GRM21BR61A476ME15L in circuits where the voltage across the capacitor could momentarily exceed 10 V (e.g., during hot-plug events, transient spikes, or upstream switching-node ringing). Even brief overvoltage can damage the dielectric and cause field failures. For applications exposed to transients, add a TVS clamp or choose the 16 V / 25 V-rated GRM21BR61C476ME15L / GRM21BR61E476ME15L as a safer drop-in upgrade sharing the same 0805 footprint.
