NFM21PC105F1C3D

Overview

The Murata NFM21PC105F1C3D is a three-terminal feedthrough capacitor from the EMIFIL NFM21P series. It features a capacitance of 1.0 µF with a tolerance of +30%/-84%. The component has a DC voltage rating of 16 V and operates within a temperature range of -40°C to +85°C. Packaged in an 0805 (2012 metric) surface-mount footprint, it measures 2.0 mm in length, 1.25 mm in width, and 0.85 mm in height. The device includes a dedicated ground terminal with a diameter of 0.6 mm and supports a rated current of 4 A.

Feature Summary

• Three-terminal architecture providing low-inductance signal filtering for high-frequency noise suppression
• Integrated ground terminal design that minimizes parasitic inductance compared to standard two-terminal capacitors
• Surface-mount construction optimized for automated assembly in compact electronic layouts

Applications

• High-speed digital signal line filtering in portable devices
• Power supply decoupling for integrated circuits requiring low-impedance paths
• EMI suppression in communication modules and data transmission interfaces

Procurement Notes

Verify the specific suffix code against official Murata documentation to confirm exact capacitance tolerance and termination specifications. Ensure the selected variant matches the required operating temperature range and physical dimensions for the target PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when space-constrained designs require superior high-frequency attenuation compared to standard MLCCs. The three-terminal structure offers lower effective series inductance, making it suitable for signals above typical bypass frequencies. Evaluate the 16V rating against peak transient voltages to ensure reliable operation without dielectric breakdown under normal circuit conditions.

Part Context

This component belongs to the Murata EMIFIL NFM21P series of three-terminal feedthrough capacitors. These parts are engineered specifically for EMI/RFI suppression in modern electronics where board real estate is limited. The series utilizes advanced ceramic materials to achieve stable performance across varying temperatures while maintaining a compact 0805 form factor for widespread compatibility.

Replacement Considerations

Direct substitutes include other Murata NFM21P series variants with matching 1.0 µF capacitance and 16V ratings, such as NFM21PC105B1C3D, provided tolerance and package dimensions align with design constraints.
