1806J1000182MCTE01

Overview

The Knowles Syfer 1806J1000182MCTE01 is a three-terminal surface-mount EMI filter capacitor designed for high-frequency noise suppression. It features a C0G (NP0) dielectric material ensuring stable capacitance across temperature variations. The component operates at a DC voltage rating of 100V with a nominal capacitance of 1800 pF and a tolerance of ±20%. Housed in an 1806 (4516 metric) package, it supports a wide operating temperature range from -55°C to +125°C. This device integrates a feed-through structure to provide effective common-mode interference filtering in compact electronic assemblies.

Feature Summary

• Three-terminal feed-through architecture for enhanced EMI suppression
• C0G (NP0) ceramic dielectric for high stability and low loss
• Surface-mount design compatible with automated assembly processes

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output noise reduction in industrial controls
• EMI mitigation in automotive electronics and infotainment systems

Procurement Notes

Verify the specific suffix 'TE01' against official Knowles Syfer documentation to confirm tape-and-reel packaging specifications and terminal plating details. Ensure that the 1806 footprint dimensions align with the target PCB layout constraints. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market. Confirm availability through authorized distributors to guarantee authenticity and traceability of the components.

Selection Notes

Select this component when high-frequency noise attenuation is required in space-constrained designs. The 1806 package offers a balance between thermal performance and mounting area. The C0G dielectric is suitable for applications requiring minimal capacitance drift over temperature. Consider the 100V rating for circuits operating within this potential range. Evaluate the insertion loss characteristics if specific frequency attenuation profiles are critical for the application.

Part Context

This part belongs to the Knowles Syfer E01 series of SMT EMI filters. The series is characterized by its lead-free construction and robust ceramic build. These capacitors are engineered to meet stringent reliability standards for demanding environments. The product line emphasizes consistent performance in suppressing electromagnetic interference across various industrial and commercial sectors.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 100V rating, 1800 pF capacitance, and three-terminal configuration. Verify that alternative parts maintain C0G dielectric properties for equivalent temperature stability. Ensure the substitute component meets the same thermal and electrical specifications without compromising the EMI filtering performance.
