1812Y5000683MXTE03

Overview

The Knowles Syfer 1812Y5000683MXTE03 is a Surface Mount Multilayer Ceramic Capacitor (MLCC) featuring X2Y architecture. It offers a capacitance of 68 nF with a ±20% tolerance and a DC voltage rating of 500 V. The component utilizes an X7R dielectric, ensuring stability across an operating temperature range of -55°C to +125°C. Designed in the 1812 (4532 metric) package, it incorporates flexible terminals for enhanced mechanical reliability.

Feature Summary

• Integrates X2Y circuit topology within a single surface-mount package to provide simultaneous common-mode and differential-mode noise suppression.
• Features flexible terminal construction designed to absorb board flex stress, reducing the risk of cracking during assembly or operation.
• Utilizes a nickel barrier electrode structure to improve solderability and long-term reliability in harsh environments.

Applications

• High-density power supply input filtering
• Automotive electronics requiring robust EMI suppression
• Industrial control systems with sensitive signal lines

Procurement Notes

Verify the complete part number including the suffix TE03, as it denotes specific packaging and termination characteristics. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain solderability and electrical performance upon installation.

Selection Notes

Select this component when space constraints require combined filtering functions in a single footprint. The X2Y design reduces component count compared to discrete capacitor networks. Evaluate the 500V rating against peak transient voltages in the application circuit to ensure adequate safety margins under all operating conditions.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability capacitors with compliant terminations. The 1812Y series designation indicates the 1812 case size and X7R temperature coefficient. The product line targets applications demanding superior mechanical durability alongside stable electrical performance.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 500V rating, 68nF capacitance, and X2Y topology. Verify that alternative components offer comparable flexibility ratings and thermal stability to maintain board integrity and filtering efficacy without redesigning the layout.
