1812J2000122MCTE03

Overview

The Knowles Syfer 1812J2000122MCTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for general electronic applications. It features a capacitance of 1200 pF with a tolerance of ±20% and utilizes C0G (NP0) dielectric material for stable performance. The component is rated for a DC voltage of 200 VDC and operates within a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) package, it measures 4.5 mm in length, 3.2 mm in width, and 2.5 mm in height. The device supports standard SMD/SMT termination types and complies with RoHS standards.

Feature Summary

• Utilizes C0G (NP0) dielectric material for high stability and low loss characteristics across the operating temperature range.
• Designed for surface-mount technology (SMD/SMT) integration into printed circuit boards.
• Complies with RoHS directives for environmental safety.

Applications

• General purpose electronic circuits requiring stable capacitance
• High-frequency signal coupling and decoupling applications
• Timing and resonant circuits where low dielectric absorption is critical

Procurement Notes

Verify the specific suffix 'E03' against official Knowles Syfer documentation to confirm packaging details such as reel or cut tape specifications. Ensure that the procurement channel provides valid traceability and authenticity certificates. Confirm that the requested quantity aligns with manufacturer minimum order requirements and standard factory pack sizes. Check for any regional distribution restrictions or shipping limitations applicable to this specific part number before finalizing orders.

Selection Notes

Select this component when a 1200 pF capacitance value is required with a 200 VDC rating in an 1812 footprint. The C0G dielectric makes it suitable for applications demanding minimal capacitance variation over temperature and voltage changes. Consider the ±20% tolerance if precise tight tolerances are not necessary. Evaluate the physical dimensions (4.5 x 3.2 x 2.5 mm) for compatibility with existing board space constraints and thermal management requirements.
