C1005X7R1H104K050BB 100nF 50V X7R Ceramic Capacitor

ElecSuppliers Part Number GuideSep 06, 2026

C1005X7R1H104K050BB is a TDK multilayer ceramic chip capacitor designed for compact electronic circuits requiring stable capacitance, low impedance and efficient high-frequency performance. It provides 0.1µF capacitance with a ±10% tolerance and a 50V DC rated voltage.

The component uses an X7R dielectric and a compact 0402 package, also identified as the 1005 metric size. Its small footprint makes it suitable for high-density PCB layouts where space around processors, ICs and power circuits is limited.

100nF Capacitance for Everyday Circuit Functions

The 0.1µF capacitance value makes C1005X7R1H104K050BB one of the common capacitor values used in electronic circuit design.

A 100nF MLCC can be placed close to integrated circuits to provide local high-frequency decoupling. It can also be used for noise suppression, signal filtering and power rail stabilization depending on the circuit topology.

Because the capacitor is non-polarized, it can be installed in either orientation when mounted on the PCB.

X7R Dielectric for Stable Performance

C1005X7R1H104K050BB uses X7R dielectric material. X7R is widely used for general-purpose decoupling and filtering because it offers a useful combination of capacitance stability, voltage capability and compact size.

The specified temperature characteristic covers -55°C to +125°C. This allows the capacitor to be used across a relatively broad operating temperature range in commercial and industrial electronic equipment.

The actual capacitance can vary with temperature and applied DC voltage, so circuit designers should consider the capacitor's DC bias characteristics when accurate capacitance is important.

50V Rating in a 0402 Package

The 50V rated voltage is an important feature of C1005X7R1H104K050BB. Compared with lower-voltage 0402 MLCCs, the 50V rating provides additional voltage margin for many control, interface and power-related circuits.

The component uses the 0402 imperial package, measuring approximately 1.00mm × 0.50mm. This small footprint helps designers increase component density and shorten PCB signal and power paths.

The compact dimensions are particularly useful in portable electronics, embedded controllers and densely populated circuit boards.

Low ESL for High-Frequency Decoupling

MLCC construction provides low equivalent series inductance, which allows C1005X7R1H104K050BB to respond effectively to high-frequency changes on a power rail.

When positioned close to an IC power pin, a 100nF capacitor can help supply transient current and reduce high-frequency voltage fluctuations. Multiple capacitors can also be distributed across a PCB to create localized decoupling points.

PCB trace length and mounting layout have a significant effect on the real-world high-frequency performance of any small ceramic capacitor.

Typical Applications

C1005X7R1H104K050BB can be used in a wide range of electronic circuits. Common applications include IC power-supply decoupling, digital circuit filtering, signal filtering, control electronics and general-purpose power-line noise suppression.

The 0402 footprint makes it particularly suitable for compact consumer electronics, communication equipment, industrial controllers, embedded systems and other high-density PCB assemblies.

Its 50V rating also allows the component to be considered for circuits where a standard 100nF capacitor needs more voltage margin than a low-voltage MLCC can provide.

Surface-Mount Manufacturing

C1005X7R1H104K050BB is designed for surface-mount assembly and is suitable for automated PCB production processes. Its small dimensions support high component density while reducing the board area required for passive components.

For production engineers, the 0402 package can help achieve compact board designs, although accurate PCB land patterns and controlled placement processes are important because of the component's small physical size.

Selecting C1005X7R1H104K050BB for a PCB

When using C1005X7R1H104K050BB, designers should evaluate capacitance tolerance, DC bias effects, operating temperature, applied voltage and the electrical requirements of the target circuit.

The 50V rating should not be treated as the desired continuous operating voltage without considering design margin. Likewise, the nominal 100nF value may decrease under DC bias depending on the operating conditions.

For standard high-frequency decoupling and filtering, however, the combination of 100nF capacitance, X7R dielectric and 0402 packaging makes C1005X7R1H104K050BB a compact option for modern PCB designs.

Compact 100nF MLCC for Dense PCB Designs

C1005X7R1H104K050BB combines a 100nF capacitance value, 50V voltage rating, ±10% tolerance and X7R dielectric in a 0402 surface-mount package.

Its small footprint and low-ESL ceramic construction make it well suited to local IC decoupling, filtering and general-purpose electronic circuits where PCB space is limited and reliable high-frequency bypass performance is required.
