1812J1000183MJTE03

Overview

The Knowles Syfer 1812J1000183MJTE03 is a multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 100 V DC voltage rating and a capacitance value of 18 nF. The component utilizes a Class 2 X7R dielectric material, providing stable performance across a wide temperature range from -55°C to +125°C. It is housed in an 1812 (4532 Metric) surface-mount package with silver termination electrodes. The device offers a tolerance of ±20% (M code), making it suitable for general decoupling and bypassing tasks where precise capacitance is not critical.

Feature Summary

• Utilizes X7R dielectric material for stable capacitance over varying temperatures
• Designed for robust surface-mount integration in compact electronic assemblies
• Features silver termination electrodes compatible with standard reflow soldering processes

Applications

• General-purpose decoupling in digital logic circuits
• Bypass applications in power supply lines
• High-reliability industrial equipment requiring stable passive components

Procurement Notes

Verify the complete part number including suffixes against official Knowles Syfer documentation to ensure correct dielectric type, voltage rating, and termination finish. Confirm RoHS compliance status and specific packaging details such as reel size or tape-and-reel specifications directly with authorized distributors or the manufacturer before placing orders.

Selection Notes

Select this component when a 1812 footprint is required with moderate capacitance and voltage handling capabilities. Ensure the application environment stays within the specified -55°C to +125°C operating range. Consider the ±20% tolerance if tighter precision is needed, alternative EIA codes should be evaluated. Verify compatibility with the target PCB layout and soldering thermal profile.

Part Context

This part belongs to the Knowles Syfer series of high-performance ceramic capacitors. The series is engineered for demanding environments, offering consistent electrical characteristics and mechanical durability. The 1812J series specifically targets applications requiring reliable surface-mount solutions with standardized dimensions for automated assembly processes.

Replacement Considerations

Consult official cross-reference guides for equivalent parts from other manufacturers. Ensure any substitute matches the 1812 package size, 100V rating, 18nF capacitance, and X7R dielectric class. Verify that termination materials and mounting configurations are compatible with existing manufacturing processes.
