1806Y0500184MJTE07

Overview

The Knowles Syfer 1806Y0500184MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a 0.18 µF capacitance with ±20% tolerance and a 50 VDC voltage rating. Utilizing C0G (NP0) dielectric, it ensures stable performance across temperatures from -55°C to +125°C. The component employs a three-terminal architecture within an 1806 (4516 metric) package, providing low inductance paths for effective EMI filtering.

Feature Summary

• Three-terminal feed-through structure for enhanced high-frequency noise attenuation
• C0G (NP0) dielectric material for minimal capacitance variation over temperature
• Low-inductance design suitable for sensitive RF and high-speed digital circuits

Applications

• High-frequency EMI filtering in communication modules
• Power supply decoupling for noise-sensitive integrated circuits
• Signal line protection in automotive electronic control units

Procurement Notes

Verify the specific suffix 'MJTE07' against official Knowles Syfer documentation to confirm terminal plating and packaging specifications. Ensure compatibility with automated pick-and-place equipment regarding the 1806 footprint dimensions. Cross-reference RoHS compliance status directly with the manufacturer's current product declaration.

Selection Notes

Select this component when low parasitic inductance is critical for signal integrity. The C0G dielectric offers superior stability compared to X7R types but provides lower volumetric efficiency. Evaluate the 50V rating against peak transient voltages in the target application circuit to ensure adequate margin.

Part Context

This part belongs to the Knowles Syfer MLCC family, specifically engineered for demanding environments. The 1806Y series denotes Class 1 ceramic capacitors optimized for precision applications. The three-terminal configuration distinguishes it from standard two-terminal MLCCs by offering superior high-frequency performance through grounded center electrodes.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 0.18 µF value, 50V rating, and three-terminal feed-through topology. Verify that alternative manufacturers offer C0G dielectric with comparable thermal stability and inductance characteristics.
