1812J1000682MJTE03

Overview

The Knowles Syfer 1812J1000682MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in the E03 pass-through series. It features an X7R dielectric with a capacitance of 6800 pF and a voltage rating of 100 V DC. The component utilizes a nickel barrier termination system, ensuring compatibility with standard reflow soldering processes. Designed for high-reliability applications, it operates within a temperature range of -55°C to +125°C. The physical dimensions conform to the 1812 (4532 metric) package outline, measuring 4.50 mm in length, 3.20 mm in width, and 2.00 mm in maximum height.

Feature Summary

• Pass-through architecture enabling direct signal or power trace integration
• Nickel barrier termination structure for robust solder joint reliability
• X7R dielectric material providing stable capacitance characteristics across operating temperatures

Applications

• High-frequency RF circuit filtering
• Power supply decoupling in compact modules
• Signal integrity management in telecommunications equipment

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm termination composition and tolerance specifications. Ensure that the selected variant meets the required environmental compliance standards for the target application. Cross-reference the part number with current datasheets to validate availability and lead times through authorized distribution channels.

Selection Notes

Select this component when a low-profile pass-through form factor is required for space-constrained designs. The X7R dielectric offers a balance between capacitance density and stability. Consider the 100V rating and 6800pF value against circuit requirements. Verify thermal management needs given the 125°C maximum operating temperature limit.

Part Context

This component belongs to the Knowles Syfer E03 series of pass-through capacitors. These devices are engineered to replace traditional discrete components by integrating filtering capabilities directly into the circuit board trace. The series supports various capacitance values and voltage ratings within the 1812 footprint, catering to modern miniaturization trends in electronic assemblies.

Replacement Considerations
