DR221-513AE

Common Mode Chokes Overview

The DR221-513AE is a surface mount common mode choke from the Bourns DR221 series, designed for data line protection. It features an inductance of 50 µH with a tolerance of +50%/-30%. The component supports a maximum DC current of 200 mA and has a maximum DC resistance of 0.32 ohms. It operates within a temperature range of -40°C to +125°C and is rated for 100V AC and 50V DC.

Common Mode Chokes Feature Summary

• Dual-line surface mount configuration for compact circuit integration
• Common mode noise suppression for data lines
• High thermal stability suitable for demanding environments

Common Mode Chokes Applications

• Data line filtering in electronic equipment
• Signal integrity protection in communication interfaces
• EMI suppression in consumer electronics

Common Mode Chokes Procurement Notes

Verify the specific suffix AE against the official Bourns datasheet to confirm packaging and compliance status. Ensure the requested quantity matches the manufacturer's standard reel specifications. Cross-reference the date code and lot number with the certificate of conformity to guarantee authenticity and traceability before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when a 50 µH inductance value is required for common mode noise reduction in low-current data applications. The 200 mA current rating dictates suitability for signal-level lines rather than power distribution. Consider the SMD package dimensions and operating temperature range to ensure compatibility with the target assembly process and environmental conditions.

Common Mode Chokes Part Context

This part belongs to the DR221 series of surface mount data line chokes manufactured by Bourns Inc. The series offers various inductance values optimized for high-frequency noise attenuation. The DR221-513AE specifically targets applications requiring moderate inductance with a compact footprint, distinguishing it from higher-power or through-hole alternatives in the broader product portfolio.

Common Mode Chokes Replacement Considerations

Consult the official Bourns DR221 series cross-reference guide for verified substitutes. Direct replacements must match the 50 µH inductance, 200 mA current rating, and 0.32 ohm DCR. Verify pinout compatibility and physical dimensions to ensure seamless integration without redesigning the PCB layout.
