Overview
The Knowles Syfer 1206Y1000273MSTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 0.027 µF with a DC voltage rating of 100 V and a current rating of 50 mA. The component utilizes an X7R dielectric material and is housed in a standard 1206 (3216 metric) package. It incorporates a nickel barrier structure and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Integrated feed-through architecture providing combined filtering and decoupling capabilities
- Nickel barrier construction enhances reliability under thermal stress conditions
- X7R dielectric material ensures stable capacitance performance across the operating temperature range
Applications
- Automotive electronics requiring AEC-Q200 compliance
- Board-flex sensitive circuit designs
- High-current signal filtering applications
Procurement Notes
Verify the specific suffix MSTE03 against official datasheets to confirm the feed-through configuration and nickel barrier specifications. Ensure compatibility with board flex requirements and current ratings before integration. Confirm availability status as supply may be restricted in certain regions.
Selection Notes
Select this component when a single SMD device is required for both decoupling and EMI suppression in space-constrained layouts. The 1206 footprint accommodates higher current handling compared to smaller packages. Verify that the X7R temperature coefficient meets the application's stability requirements.
Part Context
This part belongs to the Knowles Syfer 1206Y series, which specializes in high-reliability MLCCs. The series includes various configurations such as FlexiCap and feed-through types. This specific model integrates a feed-through design to minimize parasitic inductance while maintaining robust mechanical integrity.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 1206 feed-through capacitors only if electrical parameters and physical dimensions match exactly.
