B85121A2104A250

Overview

The B85121A2104A250 is a feed-through capacitor manufactured by EPCOS, now part of TDK Electronics. It features a capacitance value of 0.1 µF with a tolerance of ±20%. The component has a rated voltage of 600V and supports a current rating of 25 A. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides effective electromagnetic interference filtering through feed-through design
• Supports high current loads up to 25 A
• Rated for 600 V operation in demanding environments

Applications

• Industrial power supply filtering
• Electromagnetic compatibility (EMC) suppression in electronic systems
• Protection of sensitive circuits from voltage transients

Procurement Notes

Verify the specific datasheet version for mechanical dimensions and mounting requirements. Confirm that the 25 A current rating aligns with your system's thermal management capabilities. Ensure the 600 V rating exceeds your circuit's peak operating voltage. Check for any specific handling instructions regarding moisture sensitivity or installation torque.

Selection Notes

Select this component when high-current filtering is required in compact spaces. The feed-through configuration simplifies PCB layout compared to discrete components. Consider the 600 V rating for applications with significant voltage spikes. Evaluate the -40°C to +85°C range against your environmental conditions.

Part Context
