0603CS-4N3EKTS

Fixed Inductors Overview

The 0603CS-4N3EKTS is a fixed wirewound inductor with an unshielded drum core, manufactured by Delta Electronics/Components. It features a nominal inductance of 4.3 nH and a tolerance of ±10%. The component has a DC resistance (DCR) of 63 mΩ and a rated current of 700 mA. It exhibits a Q value of 22 at 250 MHz and a self-resonant frequency of 5.8 GHz. The device is housed in a 0603 (1608 Metric) surface-mount package, measuring 1.80mm x 1.16mm x 1.02mm. It operates within a temperature range of -40°C to 125°C.

Fixed Inductors Feature Summary

• Unshielded drum core construction for minimal magnetic interference
• High self-resonant frequency capability up to 5.8 GHz
• Surface-mount design optimized for automated assembly processes

Fixed Inductors Applications

• RF signal filtering circuits
• Impedance matching networks
• High-frequency power supply decoupling

Fixed Inductors Procurement Notes

Verify the specific ordering suffix 'K' confirms the ±10% tolerance rating against official datasheets. Ensure the 0603 footprint dimensions align with PCB layout requirements. Confirm RoHS3 compliance status if required by project specifications. Check manufacturer lead times as standard delivery periods may vary.

Fixed Inductors Selection Notes

Select this component when low nanohenry inductance is required for high-frequency applications. The 700 mA current rating suits moderate power levels. Consider the unshielded nature for placement relative to sensitive components. Compare DCR and Q factor against alternative suppliers for efficiency optimization.

Fixed Inductors Part Context

This part belongs to the 0603CS series of fixed inductors from Delta Electronics/Components. The series offers various inductance values in the 0603 package size. It is designed for general-purpose RF and microwave applications requiring compact, reliable passive components.

Fixed Inductors Replacement Considerations

The 0603CS-4N3EJTS is a confirmed substitute with identical electrical parameters but a ±5% tolerance. Verify package compatibility and thermal characteristics before substitution.
