KNH05X5R156M04AH

Overview

The KYOCERA AVX KNH05X5R156M04AH is a three-terminal multilayer ceramic feedthrough capacitor designed for surface-mount applications. It features an X5R dielectric material with a capacitance of 15 µF and a DC voltage rating of 4 VDC. The component operates within a temperature range of -55°C to +85°C and maintains a tolerance of ±20%. Housed in a compact 0402 (1005 metric) package measuring 1 mm x 0.5 mm x 0.65 mm, it offers low impedance characteristics suitable for high-frequency noise suppression.

Feature Summary

• Three-terminal feedthrough architecture provides superior high-frequency noise attenuation compared to standard two-terminal designs.
• Utilizes X5R dielectric technology to maintain stable capacitance performance across the specified operating temperature range.
• Compact 0402 footprint enables integration into space-constrained printed circuit board layouts.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF interference suppression in compact electronics

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal configuration and termination plating specifications. Ensure that the selected variant matches the required thermal endurance and voltage derating curves for the target application environment. Cross-reference datasheet revision dates to guarantee compliance with current manufacturing standards.

Selection Notes

Select this component when high capacitance density is required in a minimal footprint for noise-sensitive circuits. The three-terminal design is preferred over standard MLCCs for applications demanding lower effective series inductance. Evaluate the 4V rating against peak transient voltages to prevent dielectric breakdown during operation.

Part Context

This part belongs to the general-purpose MLCC family from KYOCERA AVX. It represents a specialized feedthrough variant within the broader capacitor portfolio, engineered specifically for electromagnetic interference mitigation rather than general energy storage functions.

Replacement Considerations

Direct substitutes include other 0402 three-terminal feedthrough capacitors with matching 15µF/4V/X5R specifications. Verify physical pad compatibility and electrical parameters before substitution.

FAQ
