1812Y1000224MJTE03

Overview

The Knowles Syfer 1812Y1000224MJTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.22 µF with a voltage rating of 100 VDC and an X7R dielectric material. The component operates within a temperature range of -55°C to +125°C and utilizes a flexible terminal construction to enhance board reliability. Packaged in cut tape or reel formats, it measures 4.50 mm in length, 3.20 mm in width, and has a maximum height of 0.75 mm.

Feature Summary

• Integrated pass-through architecture enables simultaneous signal transmission and high-frequency noise filtering within a single compact footprint.
• Flexible terminal design absorbs mechanical stress from printed circuit board flexing, reducing the risk of internal cracking during assembly or operation.

Applications

• High-reliability aerospace and defense electronic systems
• Automotive electronics requiring AEC-Q200 compliance
• Board-flex sensitive applications demanding enhanced mechanical durability

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct terminal flexibility and packaging type. Confirm RoHS3 compliance status and moisture sensitivity level requirements prior to integration. Cross-reference manufacturer part numbers with distributor listings to validate authenticity and current production status.

Selection Notes

Select this component when both electrical filtering and mechanical resilience are critical. The X7R dielectric provides stable capacitance over the operating temperature range. Ensure the 100V DC rating exceeds peak circuit voltages. Verify that the 1812 package dimensions fit the available PCB real estate without compromising clearance requirements.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors with soft terminals. The series targets industries where standard rigid terminations fail due to substrate movement. The 1812Y prefix indicates the specific family characteristics regarding voltage and dielectric performance.

Replacement Considerations

Direct substitutes must match the 0.22 µF capacitance, 100 VDC rating, X7R dielectric, and 1812 package size. Verify that any alternative also offers flexible terminals and pass-through functionality. Check for equivalent AEC-Q200 qualification if automotive use is intended.
