GRM155R71C104KA88D: Overview, Features, and Applications


The part number you mentioned, "GRM155R71C104KA88D," is a multilayer ceramic capacitor (MLCC) from Murata Manufacturing. These capacitors are widely used for a variety of applications due to their small size, reliability, and broad range of available values.

Here's a brief overview of this capacitor, its features, and common applications:


The GRM155R71C104KA88D is a compact SMT (Surface Mount Technology) MLCC that uses a high dielectric constant ceramic, multi-layering, and monolithic structure design to achieve high capacitance values.



  • Capacitance Value: This specific model has a nominal capacitance of 0.1 µF (or 100 nF) which is indicated by "104" in the part number. The three-digit code follows the picofarad (pF) system where the first two digits are the significant figures and the third digit is the multiplier.
  • Voltage Rating: The voltage rating of this capacitor is 16V, designated by "C" in the part number.
  • Package / Case Size: The capacitor comes in a 0402 (1005 metric) case size, which is represented by "155" in the part number.
  • Tolerance: "K" in the part number refers to the tolerance, which is ±10% for this specific capacitor.
  • Temperature Coefficient: The "R71" in the part number indicates the capacitor has an X7R temperature coefficient, meaning it can operate between -55°C and +125°C with a capacitance drift of ±15% over that range.
  • Lead Style: As an SMT (surface mount) component, the GRM155R71C104KA88D does not have any physical leads. Instead, it has metallic terminals on its ends which are soldered directly to pads on the PCB (Printed Circuit Board).


Given its electrical characteristics and small footprint, the GRM155R71C104KA88D is suitable for a wide spectrum of applications:

  • Decoupling or Bypass Capacitor: In digital electronics, it can be used as a decoupling capacitor near the power supply pins of ICs (Integrated Circuits) to filter out high-frequency noise and stabilize the power supply.

  • Filtering: In power supply circuits, they're commonly employed for removing unwanted frequencies or smoothing the output.

  • Timing Circuits: In combination with resistors, they can be used to create the time base in oscillator circuits or circuits with timing functions.

  • Signal Processing: In audio applications, these capacitors can be used for coupling and decoupling of signals.

  • General Electronics: Due to their broad characteristics, these capacitors can be found in a wide range of consumer electronics, industrial electronics, and automotive applications as a standard component in the power and signal domains.


Remember, when using capacitors in real-world applications, ensure the voltage rating of the part exceeds the maximum voltage expected in your circuit. Underrating a capacitor can lead to premature failure of the component. Always consult datasheets for other specifications such as derating information for temperature and voltage, impedance characteristics, and other relevant parameters.
