0805J0250821MCTE01

Overview

The Knowles Syfer 0805J0250821MCTE01 is a feed-through capacitor designed for surface-mount technology. It features an 820 pF capacitance with a 25 VDC voltage rating and supports a continuous current of 300 mA. The component utilizes the 0805 (2012 Metric) package outline, ensuring compatibility with standard SMD footprints while providing high-frequency noise suppression capabilities through its integrated feed-through architecture.

Feature Summary

• Integrates feed-through functionality within a compact surface-mount footprint to minimize parasitic inductance.
• Provides effective high-frequency noise attenuation for sensitive signal lines.
• Supports continuous DC bias currents up to 300 mA without performance degradation.

Applications

• High-speed data line filtering
• RF circuit noise suppression
• Sensitive analog signal conditioning

Procurement Notes

Verify the specific suffix E01 against the manufacturer's latest datasheet to confirm terminal configuration and termination material specifications. Ensure design-in compatibility with the required PCB pad layout for feed-through components. Confirm availability status directly with authorized distributors as supply levels may vary.

Selection Notes

Select this component when low-inductance filtering is critical for high-speed signals. The 300 mA current rating must exceed the maximum expected DC bias on the line. Compare physical dimensions against available board space, noting that feed-through capacitors require specific via or pad arrangements distinct from standard MLCCs.

Part Context

This part belongs to the Knowles Syfer J-series feed-through capacitors. Unlike standard multilayer ceramic capacitors, these devices incorporate a central conductor to handle current while shunting high-frequency noise to ground. This architecture offers superior high-frequency performance compared to conventional SMD capacitors in similar packages.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Evaluate other Knowles Syfer feed-through capacitors with matching 820 pF capacitance, 25 VDC rating, and 300 mA current handling. Verify mechanical footprint compatibility before substitution.
