The component has a tolerance of 20% and measures 11.43 mm x 11.43 mm x 3.702 mm. It is designed for surface mount installation and supplied in a reel package.

Arrays, Signal Transformers Feature Summary

• Dual-coil coupled inductor design within the OCTA-PAC family
• Surface mount construction for automated assembly
• RoHS compliant and lead-free manufacturing

Arrays, Signal Transformers Applications

• Battery Management Systems (BMS) cell monitoring circuits
• DC-DC converter input/output filtering
• Power supply noise suppression

Arrays, Signal Transformers Procurement Notes

Verify the specific suffix 'P' against your schematic requirements, as it denotes the dual-coil variant distinct from single-coil models like CTX300-3-R. Confirm the 500 mA current rating aligns with your thermal design. Check the 21-week standard lead time for production scheduling. Ensure the reel packaging quantity matches your line capacity. Validate RoHS compliance documentation for regulatory adherence.

Arrays, Signal Transformers Selection Notes

Select this part when a compact, dual-winding solution is required for coupled applications. The 298.39 µH value suits moderate energy storage needs. Compare the 926 mΩ DCR against efficiency targets. Consider the 11.43 mm footprint for board space constraints. Evaluate the 500 mA saturation current against peak load conditions to prevent performance degradation.

Arrays, Signal Transformers Part Context

This component belongs to the CTX series of toroidal power inductors. It shares the OCTA-PAC form factor with other variants like CTX300-2P-R. The series is characterized by high magnetic coupling and low profile. It serves as a specialized passive component for power electronics, differing from general-purpose chokes by its integrated dual-coil architecture.

Arrays, Signal Transformers Replacement Considerations

CTX300-2P-R offers similar dimensions but different inductance values. Verify electrical parameters before substitution. No direct pin-compatible substitutes are confirmed in public data.
