Overview
The Knowles Syfer 1206Y0500102MSTE03 is a surface-mount feed-through capacitor with a capacitance of 1000 pF and a voltage rating of 50 VDC. It utilizes X7R dielectric material and offers a tolerance of ±20%. The component features a 1206 (3216 Metric) package size and incorporates FlexiCap technology with a nickel barrier for enhanced mechanical stability. Designed for high-frequency applications, it supports a continuous current of 50 mA and operates within a temperature range of -55°C to +125°C.
Feature Summary
- Integrates FlexiCap technology with a nickel barrier structure to improve mechanical robustness against board flexing.
- Functions as a feed-through capacitor designed for effective high-frequency noise suppression in signal lines.
- Utilizes X7R ceramic dielectric to maintain stable electrical performance across the specified operating temperature range.
Applications
- High-speed digital signal line filtering
- RF circuit noise suppression
- Data bus protection
Procurement Notes
Verify the specific suffix codes against official datasheets to confirm terminal configuration and barrier materials. Ensure compatibility with automated pick-and-place equipment regarding the reel packaging format. Confirm that the 50 mA current rating meets the operational requirements of the target circuit without derating issues.
Selection Notes
Select this component when high-frequency EMI suppression is required on low-current signal traces. The 1206 footprint provides a balance between parasitic inductance reduction and board space efficiency. Consider the nickel barrier feature if the application involves significant mechanical stress or board warping during assembly.
Part Context
This part belongs to the Knowles Syfer FlexiCap series, which specializes in MLCCs with reinforced terminations. The 1206Y prefix indicates the 1206 case size and general product family characteristics. The MSTE03 suffix denotes specific construction details including the X7R dielectric and feed-through topology.
Replacement Considerations
Direct substitutes must match the 1206 feed-through form factor, 50V rating, and 1nF capacitance. Verify that alternative components offer comparable high-frequency impedance characteristics and similar mechanical termination structures to ensure reliable performance in existing layouts.
