Fixed Inductors Procurement Notes

Verify the specific suffix code against the manufacturer's ordering guide to confirm tolerance accuracy. Ensure the procurement documentation explicitly states compliance with RoHS standards. Cross-reference the part number with the official Central Technologies datasheet to validate the 0402 footprint dimensions and terminal configuration before finalizing orders.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 4.3 nH is required for high-frequency circuitry. The ceramic core provides thermal stability up to 125°C, making it suitable for demanding environments. Consider the 0.11 Ω DC resistance limit for power efficiency requirements and ensure the 0.76 A current rating aligns with the application's peak load conditions.

Fixed Inductors Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors from Central Technologies. The series offers a wide range of inductance values from 1.6 nH to 390 nH in a compact 0402 package. These components are engineered for general-purpose applications requiring reliable performance in space-constrained electronic designs.

Fixed Inductors Replacement Considerations

Consult the official Central Technologies substitution list for verified equivalents. Direct replacements must match the 4.3 nH inductance, ±5% tolerance, 0402 package size, and ceramic core construction to maintain circuit integrity.
