1812Y2000123MXTE03

Overview

The Knowles Syfer 1812Y2000123MXTE03 is a multilayer ceramic capacitor (MLCC) in the FlexiCap series. It features an X7R dielectric with a capacitance of 12 nF and a DC voltage rating of 200 VDC. The component utilizes a 1812 (4532 metric) surface mount package with flexible terminations to enhance mechanical reliability. It operates within a temperature range of -55°C to +125°C and has a tolerance of ±20%.

Feature Summary

• Flexible soft terminations designed to reduce stress on solder joints during board flexing or thermal cycling.
• X7R dielectric material providing stable capacitance performance across a wide operating temperature range.

Applications

• General-purpose decoupling and bypass applications in surface mount circuits.
• Electronic assemblies requiring resistance to mechanical shock and vibration due to flexible terminations.
• Industrial equipment operating under varying thermal conditions.

Procurement Notes

Verify the specific suffix E03 against the manufacturer's current datasheet to confirm packaging details and marking specifications. Ensure compatibility with standard reflow profiles for components with flexible terminations. Confirm RoHS compliance status through official documentation prior to integration into regulated products.

Selection Notes

Select this component when high mechanical reliability is required alongside standard X7R performance characteristics. The 1812 footprint offers a balance between capacitance density and physical size. Verify that the 200V rating meets the circuit's peak voltage requirements, including derating considerations for temperature and ripple current effects.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, which specializes in MLCCs with compliant terminations. These capacitors are engineered to mitigate cracking risks associated with rigid terminations in high-reliability environments. The 1812Y series specifically targets applications demanding robustness without sacrificing electrical performance standards.

Replacement Considerations

Direct substitutes must match the 1812 package, 12nF capacitance, 200V rating, X7R dielectric, and flexible termination type. Generic X7R MLCCs with rigid terminations may not provide equivalent mechanical durability. Consult manufacturer cross-reference lists for verified equivalents.
