Overview
The B85321A2502W160 is a feed-through capacitor from the EPCOS B85321 series, designed for EMC filtering applications. It features a metal package with threaded terminals and panel mount installation. The component has a rated voltage of 250 V AC (50/60 Hz) or 600 V DC, with a capacitance value of 2500 pF. It supports a maximum frequency of 1000 MHz and offers high insertion loss performance. The unit measures 30 mm in diameter and 81 mm in height.
Feature Summary
- Provides effective electromagnetic interference suppression through feed-through design
- Utilizes a robust metal package for durability and shielding
- Features threaded terminals for secure panel mounting
Applications
- EMC filtering in industrial electronics
- Power supply input/output noise reduction
- Signal line protection in communication equipment
Procurement Notes
Verify the specific suffix W160 against official TDK/EPCOS documentation to confirm terminal configuration and compliance status. Ensure the selected variant matches the required voltage rating of 250 V AC or 600 V DC for your circuit. Cross-reference the physical dimensions and mounting style with your enclosure specifications before finalizing procurement.
Selection Notes
Select this component when high-frequency noise attenuation is critical in power or signal lines. The 2500 pF capacitance offers a balance between filtering effectiveness and leakage current. Consider the 600 V DC rating if operating in DC-dominated environments. Ensure the panel thickness accommodates the threaded terminal requirements for proper sealing and mechanical stability.
Part Context
This part belongs to the EPCOS B85321 series of feed-through capacitors, manufactured by TDK Electronics. The series is engineered for demanding EMC applications requiring reliable noise suppression. These components are widely used in industrial and automotive sectors where robust filtering and long-term stability under varying environmental conditions are essential.
Replacement Considerations
Check for direct substitutes within the B85321 family with compatible capacitance and voltage ratings. Verify that any alternative maintains the same physical footprint and mounting interface to ensure seamless integration without redesigning the PCB or panel layout.
