Overview
The Knowles Syfer 1812J2000272MCTE03 is a feed-through multilayer ceramic capacitor designed for surface mount technology. It features a capacitance of 2700 pF and a DC voltage rating of 200 VDC. The component operates within a temperature range of -55°C to +125°C and utilizes C0G (NP0) dielectric material. Housed in an 1812 (4532 metric) package, it includes a 50 mA current rating specification.
Feature Summary
- Integrates feed-through architecture for enhanced electromagnetic interference suppression
- Utilizes C0G (NP0) dielectric for stable capacitance performance across operating temperatures
- Supports high-frequency signal filtering through integrated ground plane structure
Applications
- High-frequency circuit filtering
- Electromagnetic interference suppression in sensitive electronics
- Signal integrity management in RF applications
Procurement Notes
Verify the specific lead time and availability status directly with authorized distributors or the manufacturer before procurement planning. Confirm that the 50 mA current rating aligns with your application requirements. Ensure compatibility with standard SMT assembly processes for the 1812 footprint. Check for any regional sales restrictions or shipping limitations applicable to this specific part number.
Selection Notes
Select this component when both high-frequency filtering and structural integration are required. The feed-through design reduces parasitic inductance compared to standard MLCCs. Consider the 200 VDC rating and 2700 pF value for appropriate circuit impedance matching. Verify thermal stability needs against the C0G characteristic for precision applications.
Part Context
This component belongs to the Knowles Syfer feed-through capacitor series, distinct from standard multilayer ceramic capacitors. It combines passive filtering capabilities with a grounded center conductor structure. The 1812J prefix indicates the case size and voltage class within the manufacturer's portfolio.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative feed-through capacitors from the same manufacturer only if they match the 1812 footprint, 200 VDC rating, and 2700 pF capacitance.
