Product details
Overview
GRM31CR61C476ME44L from Murata Electronics is a multilayer ceramic capacitor (MLCC) featuring a capacitance of 47µF, a rated voltage of 16V, and an X5R dielectric system in a 1206 (3216 Metric) package. The device is designed for power supply filtering, bulk capacitance, decoupling, bypass, and noise suppression applications across industrial, consumer, communication, and embedded electronic systems.
As part of Murata's GRM series MLCC portfolio, GRM31CR61C476ME44L combines high capacitance density, compact size, low ESR characteristics, and stable performance over temperature. It is commonly used in DC/DC converters, FPGA power rails, processor power networks, wireless modules, industrial control systems, and high-density PCB designs requiring efficient power stabilization.
Electrical Characteristics
| Characteristic | Design Impact |
|---|---|
| X5R Dielectric | Provides stable capacitance over a wide operating temperature range. |
| Low ESR | Improves switching power supply efficiency and transient response. |
| High-Frequency Performance | Supports effective suppression of power rail noise and EMI. |
| High Capacitance Density | Reduces PCB area compared with larger electrolytic solutions. |
| DC Bias Effect | Effective capacitance decreases as applied DC voltage increases. |
| Temperature Stability | Capacitance variation remains within X5R specification limits. |
Like all high-value MLCC capacitors, GRM31CR61C476ME44L experiences capacitance reduction under DC bias conditions. Designers should evaluate actual operating voltage and capacitance requirements during power supply design to ensure sufficient effective capacitance is maintained.
Design Considerations
| Design Area | Recommendation |
|---|---|
| Input Filtering | Place close to DC/DC converter input pins to reduce input ripple. |
| Output Filtering | Install near regulator outputs to improve transient response. |
| Power Rail Decoupling | Position near FPGA, MCU, ASIC, or processor power pins. |
| Ground Layout | Use low-impedance ground connections for optimal filtering performance. |
| Mechanical Stress | Avoid board flexing to reduce ceramic cracking risk. |
| Parallel Usage | Multiple capacitors can be combined to improve ripple suppression. |
For high-current switching regulators, combining GRM31CR61C476ME44L with smaller-value MLCC capacitors can improve broadband filtering performance and reduce overall power rail impedance.
Applications
| Application Area | Function | Benefit |
|---|---|---|
| DC/DC Converters | Input and output filtering | Reduces ripple and improves power stability |
| FPGA & Processor Power Rails | Bulk decoupling capacitor | Supports transient current demand |
| Industrial Control Systems | Noise suppression | Improves system reliability |
| Wireless Communication Modules | Power stabilization | Enhances RF system performance |
| Consumer Electronics | Power supply filtering | Improves operational stability |
| Embedded Systems | Local bypass capacitor | Reduces voltage fluctuations |
Equivalent & Alternatives
| Part Number | Manufacturer | Capacitance | Voltage | Package |
|---|---|---|---|---|
| CL31A476MPHNNNE | Samsung Electro-Mechanics | 47µF | 16V | 1206 |
| C3216X5R1C476M160AC | TDK | 47µF | 16V | 1206 |
| JMK316ABJ476ML | Taiyo Yuden | 47µF | 16V | 1206 |
When selecting alternatives, engineers should compare effective capacitance under DC bias, ESR characteristics, temperature performance, availability, and mechanical reliability rather than relying solely on nominal capacitance specifications.
Quality & Reliability
