1806J0500183MJTE07

Overview

The Knowles Syfer 1806J0500183MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.018 µF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Housed in a compact 1806 (4516 metric) package, it supports a continuous current of 2 A. This device integrates filtering capabilities directly into the circuit trace, offering a low-profile solution for EMI reduction in space-constrained applications.

Feature Summary

• Integrates feed-through filtering functionality within a standard SMD footprint to minimize electromagnetic interference.
• Supports continuous current loads up to 2 Amperes without performance degradation.
• Utilizes X7R ceramic dielectric to maintain capacitance stability under varying thermal conditions.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF circuit noise suppression

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm terminal configuration and termination plating specifications. Ensure that the selected variant matches the required current handling and voltage derating criteria for the target application environment. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a combined power transmission and signal filtering function is required in a single surface-mount package. The 1806 form factor provides a balance between current capacity and board space efficiency. Consider the X7R temperature coefficient for environments with significant thermal fluctuations. Evaluate the parasitic inductance characteristics relative to the switching frequency of the connected circuitry.

Part Context

This part belongs to the Knowles Syfer Syfer Power series, which specializes in high-reliability multilayer ceramic capacitors. The J-series designation typically indicates specific construction standards for robustness. As a feed-through type, it differs from standard parallel-plate MLCCs by passing current through the center electrode while shunting noise to ground or chassis.

Replacement Considerations

Direct replacements must match the 1806 footprint, 50V rating, 0.018µF capacitance, and 2A current capability. Verify that alternative feed-through capacitors offer comparable insertion loss characteristics at the target frequencies. Check for compatible termination materials if soldering constraints exist.
