1806J0500330MCTE01

Overview

The Knowles Syfer 1806J0500330MCTE01 is a three-terminal feed-through capacitor designed for surface mount technology. It features a 33 pF capacitance with a ±20% tolerance and a 50 VDC voltage rating. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a compact 1806 (4.5mm x 1.6mm) package, it incorporates nickel barrier terminations for enhanced reliability. This EMI filter provides efficient noise suppression in high-frequency circuits.

Feature Summary

• Three-terminal feed-through architecture for effective electromagnetic interference filtering
• C0G (NP0) dielectric material providing high stability and low loss characteristics
• Nickel barrier termination structure for improved solderability and environmental resistance

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output noise suppression in industrial control systems
• EMI mitigation in sensitive analog and mixed-signal circuitry

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal composition and packaging configuration. Ensure compatibility with automated placement equipment regarding the 1806 footprint dimensions. Cross-reference RoHS compliance status with current regulatory requirements before integration into final assemblies.

Selection Notes

Select this component when space-constrained designs require superior high-frequency attenuation compared to standard two-terminal capacitors. The three-terminal design offers lower parasitic inductance, making it suitable for applications demanding precise impedance matching and minimal signal distortion in RF environments.

Part Context

This part belongs to the Knowles Syfer E01 series of high-reliability multilayer ceramic capacitors. The series is engineered for demanding electronic environments, offering consistent electrical properties and robust mechanical integrity. The 1806 form factor balances component density with thermal management capabilities.

Replacement Considerations

Direct substitutes must match the 33 pF value, 50 VDC rating, C0G dielectric, and 1806 three-terminal package. Verify that alternative components maintain equivalent insertion loss characteristics and physical terminal spacing to ensure board-level compatibility.
