ZB1051-AED

Overview

The ZB1051-AED is a flyback converter transformer manufactured by Coilcraft, designed for use in DC/DC converters and switched-mode power supplies (SMPS). This surface-mount component operates at a frequency of 300kHz. It provides an isolation rating of 1500Vrms between the primary and secondary windings. The device features specific inductance measurements taken at 300 kHz with 0.1 Vrms excitation, including minimum inductance specifications under 3 Adc bias conditions.

Feature Summary

• Designed specifically for flyback converter topologies within DC/DC conversion systems
• Provides high-voltage isolation capability suitable for safety-critical applications
• Optimized for operation at switching frequencies up to 300kHz

Applications

• DC/DC converter modules
• Switched-mode power supply (SMPS) designs
• Flyback transformer implementations

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and tape-and-reel configuration. Confirm that the 1500Vrms isolation rating meets your system's safety requirements. Check datasheet specifications for leakage inductance limits measured with shorted secondaries. Ensure compatibility with 300kHz operating frequencies and required inductance values under load conditions.

Selection Notes

Select this component when designing flyback converters requiring surface-mount integration. Consider the 300kHz operational frequency limit and 1500Vrms isolation barrier. Evaluate primary inductance requirements at 0.1 Vrms and 3 Adc bias. Verify physical footprint constraints for surface-mount assembly. Ensure thermal management aligns with SMPS application demands.

Part Context

This component belongs to the ZB105x-AE series of flyback transformers from Coilcraft. The series includes variants like ZB1050-AE and ZB1053-AED, sharing similar design principles for SMPS applications. These components are engineered for compact power conversion solutions requiring reliable magnetic coupling and electrical isolation in modern electronic devices.

Replacement Considerations

Consult official Coilcraft documentation for direct substitutes within the ZB105x-AE family. Verify pinout compatibility and inductance tolerances before substitution. Ensure replacement parts maintain equivalent 1500Vrms isolation ratings. Confirm surface-mount package dimensions match existing PCB layouts.
