GRM155R71C104KA88D MLCC: Working Principle, Pinout and Alternatives

GRM155R71C104KA88D Introduction

The GRM155R71C104KA88D is a high-performance multilayer ceramic capacitor (MLCC) manufactured by Murata. Featuring a non-polarized design, it offers excellent temperature stability and frequency characteristics. This capacitor is ideal for use in space-constrained and performance-critical circuits, such as those found in portable electronic devices, communication equipment, and power modules. It is widely applied in decoupling, filtering, and bypass applications.

GRM155R71C104KA88D Working Principle

The operating principle of the GRM155R71C104KA88D is based on the fundamental structure and dielectric properties of multilayer ceramic capacitors (MLCCs). It consists of multiple alternating layers of ceramic dielectric and internal electrodes stacked together. 

When a voltage is applied across its terminals, electric charges accumulate on the electrodes, creating an electric field between them and storing electrical energy. The ceramic dielectric provides excellent insulation, effectively separating the electrodes and enabling a high capacitance value within a compact package.

How to Use GRM155R71C104KA88D?

GRM155R71C104KA88D can be mounted in either direction on the PCB since it is a non-polarized component. During the assembly process, the capacitor should first be precisely placed on the designated PCB pads using a pick-and-place machine. Then, it is soldered using a reflow soldering process. It is recommended to keep the soldering temperature profile within the capacitor’s rated limits, with a peak temperature not exceeding 260°C, to prevent damage or degradation due to overheating.

In addition, care should be taken to avoid applying mechanical stress to the capacitor after soldering, such as bending the PCB or accidental impacts, as this may cause cracking in the ceramic body or solder joint failures. Proper handling and assembly procedures ensure the capacitor’s reliable performance in electronic circuits.
