2727-21F

Fixed Inductors Overview

The Delevan 2727-21F is a leaded power inductor featuring a molded toroidal core. It provides an inductance of 470 µH with a tolerance of 1%. The component has a maximum DC resistance of 27 Ohms and supports a maximum DC current of 84 mA. It exhibits a minimum Q factor of 55 and a self-resonant frequency of 3.9 MHz. Physical dimensions include a length of 7.11 mm, width of 4.06 mm, and height of 7.62 mm, with a radial vertical mounting style.

Fixed Inductors Feature Summary

• Molded toroidal coil construction for stable performance
• Radial vertical leaded termination for PCB mounting
• Unshielded design suitable for non-critical magnetic environments

Fixed Inductors Applications

• RF circuit filtering
• Power supply chokes
• Signal processing stages

Fixed Inductors Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm manufacturing origin and specific lot codes upon order placement. Check for alternate suffixes if tighter tolerances or different current ratings are required. Ensure PCB layout accommodates the specified radial lead spacing and physical footprint constraints.

Fixed Inductors Selection Notes

Select this component when a high-inductance value with tight tolerance is required in a through-hole format. The toroidal core offers superior efficiency compared to standard bobbin types. Consider the low current rating and high DC resistance when designing power paths. Verify that the unshielded nature does not interfere with nearby sensitive components.

Fixed Inductors Part Context

This part belongs to the Delevan 2727 series of fixed inductors. The series utilizes molded toroidal technology to achieve high Q factors and stability. It serves as a specialized solution for applications requiring precise inductance values in a robust, leaded package format distinct from surface-mount alternatives.

Fixed Inductors Replacement Considerations

The 2727-21H is a verified substitute offering identical electrical specifications but with a 3% tolerance instead of 1%. Both parts share the same physical dimensions and mounting style.
