Overview
The B85121A2504A630 is a feedthrough capacitor from the EPCOS (TDK) B85121 series. It features a capacitance of 0.5 µF and a rated voltage of 600 V DC. The component utilizes an axial package with threaded terminals, specifically M6 thread size. Its physical dimensions are 55.00 mm in length and 55.00 mm in diameter. Designed for high-frequency noise suppression, it provides significant insertion loss performance suitable for electromagnetic compatibility applications.
Feature Summary
- Feedthrough design for effective electromagnetic interference suppression
- Threaded terminal construction for secure panel mounting
- High capacitance density within a compact axial form factor
Applications
- Electromagnetic compatibility filtering in electronic enclosures
- Power supply input/output noise suppression
- Signal line filtering in industrial control systems
Procurement Notes
Verify the specific suffix code to confirm terminal thread specifications and capacitance tolerance. Confirm current availability status as distribution channels may vary for discontinued or legacy components. Ensure mechanical fitment matches the required panel thickness and mounting hardware constraints before procurement.
Selection Notes
Select this component when high-frequency attenuation is required at 600 V DC ratings. The threaded axial format is ideal for chassis-mounted installations where robust mechanical connection is necessary. Compare insertion loss characteristics against system requirements to ensure adequate noise reduction without affecting signal integrity.
Part Context
This part belongs to the B85121 series of feedthrough capacitors manufactured by TDK Electronics under the EPCOS brand. These components are engineered for demanding EMC environments, offering reliable performance in power and signal conditioning applications across various industrial sectors.
Replacement Considerations
Check for direct cross-references within the B85121 series with compatible thread sizes. Verify that alternative feedthrough capacitors match the 0.5 µF capacitance and 600 V rating while maintaining similar physical dimensions for panel cutout compatibility.
