1812J5000682MJTE03

Overview

The Knowles Syfer 1812J5000682MJTE03 is a feed-through capacitor with a capacitance of 6800 pF and a voltage rating of 500V. It features a tolerance of ±20% (M) and utilizes C0G/NP0 dielectric characteristics. Designed for the 1812 (4532 metric) surface-mount package, this component supports a maximum current of 50 mA. It operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Feed-through architecture providing integrated EMI filtering capabilities
• High-temperature stability ensured by C0G/NP0 dielectric material
• Robust construction suitable for high-reliability applications

Applications

• High-frequency signal line filtering
• Power supply input/output noise suppression
• EMI/RFI mitigation in sensitive electronic circuits

Procurement Notes

Verify the specific terminal configuration and pinout against the official datasheet before integration. Confirm that the 50 mA current rating aligns with the circuit requirements. Ensure the 1812 footprint matches the PCB layout design. Check for any specific handling instructions regarding the feed-through structure during assembly.

Selection Notes

Select this component when simultaneous decoupling and filtering are required in a single package. The C0G dielectric ensures minimal capacitance variation over temperature and voltage. Consider the 50 mA current limit when designing for power lines. The 1812 size offers a compact solution for space-constrained boards requiring high-frequency performance.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, designed for high-performance filtering. It combines the functions of a capacitor and an inductor in one component. The 1812J series typically denotes standard termination options. This specific model integrates a metal electrode design for enhanced durability and electrical performance in demanding environments.

Replacement Considerations

Direct substitutes include other 1812 feed-through capacitors with identical 6800 pF capacitance, 500V rating, and 50 mA current handling. Verify that alternative parts maintain the same C0G dielectric properties and physical dimensions to ensure board compatibility.
