The GRM40R472K50C500 is a multilayer ceramic capacitor (MLCC) manufactured by Murata Electronics North America. It is designed for general-purpose applications in electronic circuits where a stable capacitance value is required for decoupling, bypassing, or filtering.

Applications

• Decoupling capacitors in power supplies: Provides a stable voltage source by filtering out noise and voltage fluctuations.
• Bypass capacitors in digital circuits: Shunts high-frequency noise to ground, preventing it from interfering with circuit operation.
• Filtering in audio circuits: Blocks unwanted frequencies and allows desired frequencies to pass through.
• General purpose usage in consumer electronics: Used in a multitude of devices from mobile phones to televisions.
• Industrial electronic equipment: Used in various industrial control and automation systems.

Features

• Capacitance: 4700pF (picofarads) which is equal to 4.7nF.
• Voltage rating: 50V (volts), the maximum DC voltage that can be safely applied to the capacitor.
• Temperature Characteristic: R indicates a Class 2 dielectric material with a specific temperature coefficient of capacitance. X5R is a common type, but always check the datasheet to confirm.
• Tolerance: K tolerance (±10%) indicates the possible variation in the actual capacitance value.
• SMT (Surface Mount Technology): Designed for automated assembly onto circuit boards using reflow soldering.

Benefits

• Stable capacitance: Provides a relatively stable capacitance value over temperature.
• Compact size: Allows for high-density component placement on circuit boards.
• Cost-effective: MLCCs are generally a cost-effective solution for capacitance requirements.
• Reliable performance: Provides dependable operation in a variety of electronic circuits.
• RoHS compliant: Complies with the Restriction of Hazardous Substances directive, making it environmentally friendly.

Additional Details

The GRM series is a well-known and widely used family of MLCCs from Murata. The 'R' temperature characteristic usually implies an X5R dielectric which offers a good compromise between capacitance stability and cost. Refer to the manufacturer's datasheet for complete specifications, including the precise temperature coefficient of capacitance, insulation resistance, and dissipation factor. The capacitance will vary within a specified range (e.g. ±15%) over the operating temperature range (typically -55°C to +85°C). This component is a reliable choice for numerous applications where a stable and dependable capacitance is needed. Knowing the exact temperature coefficient of capacitance is vital for choosing this capacitor for circuits operating in varying temperature environments. The 'C500' suffix likely refers to packaging details but consult the datasheet to be certain.
