1806Y0250222MJTE07

Overview

The Knowles Syfer 1806Y0250222MJTE07 is a multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an X7R dielectric material with a capacitance of 2.2 nF and a tolerance of ±20%. The component is rated for a DC voltage of 25V and utilizes a FlexiCap nickel barrier termination system to enhance mechanical reliability. Housed in an 1806 package, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Incorporates FlexiCap flexible terminations combined with a nickel barrier to absorb mechanical stress and prevent cracking during board flexing.
• Functions as a three-terminal EMI filter structure to provide enhanced electromagnetic interference suppression compared to standard two-terminal designs.
• Utilizes X7R dielectric characteristics to maintain stable capacitance performance across a wide industrial temperature range.

Applications

• High-reliability electronic assemblies requiring resistance to mechanical shock and vibration
• Circuit boards susceptible to flexure or warping during assembly and operation
• Signal lines requiring electromagnetic interference filtering in compact form factors

Procurement Notes

Verify the specific suffix 'MJTE07' against official Knowles Syfer documentation to confirm the presence of the nickel barrier and three-terminal configuration. Ensure that the procurement channel provides genuine components with traceable manufacturing data. Cross-reference the RoHS compliance status and environmental declarations directly from the manufacturer's current datasheet before finalizing orders.

Selection Notes

Select this component when board flexibility is a primary concern, as the FlexiCap terminations mitigate stress-induced failures common in rigid-termination capacitors. The three-terminal architecture offers superior high-frequency noise attenuation compared to standard MLCCs. Confirm that the 25V rating and 2.2 nF value align with the circuit requirements while ensuring the 1806 footprint fits the available PCB space.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in robust ceramic capacitors for demanding environments. The 1806Y prefix indicates the 1806 case size and X7R dielectric type. The MJTE07 suffix specifies the termination material, barrier layer, and packaging format, distinguishing it from standard commercial grade parts.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 25V rating, 2.2 nF capacitance, and specifically the three-terminal EMI filter topology with flexible terminations. Standard two-terminal X7R capacitors are not electrically equivalent due to the lack of filtering capability and different mechanical stress profiles.
