Overview
The Knowles Syfer 1806J0250184MJTE07 is a three-terminal multilayer ceramic capacitor (MLCC) designed for EMI filtering applications. It features an X7R dielectric with a capacitance of 180 nF and a tolerance of ±20%. The component has a DC voltage rating of 25 VDC and operates within a temperature range of -55°C to +125°C. It utilizes a 1806 (4516 metric) surface-mount package with nickel barrier and 100% tin terminations.
Feature Summary
- Three-terminal architecture provides enhanced high-frequency noise attenuation compared to standard two-terminal capacitors.
- X7R dielectric material ensures stable capacitance performance across the specified industrial temperature range.
- Nickel barrier and 100% tin termination system supports reliable soldering processes and corrosion resistance.
Applications
- EMI/RFI suppression in power supply input stages
- High-frequency noise filtering in sensitive analog circuits
- Signal integrity protection in digital data lines
Procurement Notes
Verify the specific suffix 'T07' against the manufacturer's latest datasheet to confirm terminal configuration and packaging details. Ensure compatibility with PCB footprint dimensions for the 1806 case size. Confirm RoHS compliance status through official documentation prior to integration into regulated products.
Selection Notes
Select this component when superior high-frequency attenuation is required over standard MLCCs. The three-terminal design offers lower effective series inductance (ESL). Verify that the 25V rating meets the circuit's peak voltage requirements and that the 180nF value aligns with the target filter cutoff frequency specifications.
Part Context
This part belongs to the Knowles Syfer Syfer Power or general MLCC portfolio, specifically engineered for robustness in demanding environments. The 1806 case size balances capacitance density with physical footprint constraints, making it suitable for compact electronic assemblies requiring effective electromagnetic interference mitigation.
Replacement Considerations
Direct substitutes must match the 1806 footprint, 25V rating, 180nF capacitance, and three-terminal structure. Verify equivalent EMI performance characteristics and thermal stability before substitution.
