GRM155R71H104KE14D 100nF 50V X7R MLCC for Compact Electronics

ElecSuppliers Part Number GuideAug 15, 2026

The GRM155R71H104KE14D is a Murata multilayer ceramic capacitor designed for compact electronic circuits. With a nominal capacitance of 100nF and an X7R dielectric, it is the kind of component commonly used for local bypassing and signal filtering.

Its small package is particularly useful when PCB space is limited. Instead of using a larger capacitor and placing it farther away from an IC, a small MLCC can be positioned close to the relevant power or signal connection.

That is often the more practical solution on a densely populated board.

100nF for Local Decoupling

100nF is one of the most frequently used capacitor values in digital electronics.

When an IC switches, its current demand can change very quickly. A nearby bypass capacitor can provide a short local path for transient current and reduce the amount of high frequency disturbance travelling through the wider power network.

This is why a board may contain dozens of 100nF capacitors even though a much larger capacitor is already installed somewhere on the main supply rail.

The 0402 Advantage

The GRM155 series is associated with the compact 0402 size.

At this scale, PCB placement becomes much more flexible. A capacitor can be positioned very close to an IC pin, sensor or other circuit node without using significant board area.

This is particularly useful in:

• Mobile electronics

• Wearable devices

• Sensor modules

• Compact controllers

• Communication equipment

• High density PCBs

The trade-off is that very small components require more care during PCB assembly and inspection.

X7R Dielectric

The X7R dielectric is widely used for general purpose decoupling.

It provides a useful combination of capacitance stability and temperature performance for many electronic applications. It is not normally selected when extremely precise capacitance is required, but it is well suited to ordinary bypass and filtering duties.

For a design that simply needs a stable 100nF capacitor around an IC, X7R is a familiar choice.

Reading the 104 Code

The 104 portion of the part number represents the nominal capacitance.

It corresponds to 100nF, or 0.1uF.

The rest of the MPN is equally important. A large number of ceramic capacitors share the same 100nF value, but they can differ in package size, dielectric, voltage rating and tolerance.

That is why the complete GRM155R71H104KE14D number should be retained when the component is part of a production BOM.

Where It Can Be Used

GRM155R71H104KE14D can be considered for a range of low power electronic applications.

Typical uses include IC bypassing, digital circuit decoupling, signal filtering and general power rail noise reduction.

In a microcontroller board, for example, a small MLCC can be positioned directly beside the MCU power pins. In a sensor module, the same type of capacitor may be used to keep the local supply cleaner.

The exact placement and quantity depend on the circuit design.

What About DC Bias

Even with a simple 100nF MLCC, the actual operating capacitance can depend on the applied voltage.

This effect becomes especially relevant with ceramic capacitors using high capacitance values, but designers should still select components based on the complete electrical specification rather than assuming that the nominal value tells the entire story.

For precision or particularly sensitive circuits, the manufacturer's electrical characteristics should be checked under the intended operating conditions.

GRM155R71H104KE14D Replacement

A replacement needs to match the requirements of the PCB rather than just the capacitance.

The package size is especially important here. A 100nF capacitor in a 0603 package is not automatically a suitable substitute for a 0402 component when the PCB footprint has already been fixed.

Voltage rating, dielectric, tolerance and other electrical characteristics should also be compared.

Sourcing GRM155R71H104KE14D

When looking for GRM155R71H104KE14D suppliers, searching by the complete MPN is the safest approach.

Generic searches such as "100nF 0402 capacitor" produce many alternatives and make it harder to identify the exact component used in the original design.

For production purchasing, confirm the full part number, manufacturer, package, electrical specifications and product availability before placing an order.

For compact PCB designs that need a 100nF X7R MLCC in a very small package, GRM155R71H104KE14D is a useful part number to evaluate for local decoupling and filtering.
