B85121A2253C160

Overview

The B85121A2253C160 is a feed-through capacitor manufactured by EPCOS (TDK Electronics). It features an axial package with a capacitance of 0.025 µF and a rated voltage of 600V. The component has a tolerance of ±20%. This part is currently classified as obsolete.

Applications

• Power supply filtering
• Battery charger circuits
• Portable electronic device protection

Procurement Notes

Verify the obsolete status before procurement planning, as availability may be limited to surplus or secondary markets. Confirm that the axial leaded format and 600V rating align with the target design requirements. Ensure compatibility with existing PCB layouts due to the specific physical dimensions associated with this feed-through configuration.

Selection Notes

Select this component for applications requiring high-frequency noise suppression in power lines where a 600V DC rating is necessary. The 0.025 µF value provides specific filtering characteristics suitable for certain power supply topologies. Consider the axial form factor when designing for panel mounting or specific chassis integration scenarios.

Part Context

This component belongs to the EPCOS feed-through capacitor series, designed for electromagnetic interference (EMI) suppression. Feed-through capacitors utilize the conductive housing as a ground connection, offering superior high-frequency performance compared to standard two-terminal capacitors. They are integral to ensuring signal integrity and compliance in sensitive electronic environments.

Replacement Considerations

Due to the obsolete status, direct replacements must be sourced from surplus distributors. Evaluate alternative feed-through capacitors from TDK or other manufacturers with matching 0.025 µF capacitance, 600V rating, and compatible axial dimensions to ensure mechanical and electrical interchangeability.
