0603HP-121EJTS

Fixed Inductors Overview

The Delta Electronics/Components 0603HP-121EJTS is a fixed wirewound inductor with a ceramic drum core, housed in an unshielded 0603 (1608 metric) surface-mount package. It offers an inductance of 120 nH with ±5% tolerance and a DC resistance of 720 milliohms. The component supports a rated current of 420 mA and achieves a Q factor of 47 at 250 MHz. Its self-resonant frequency reaches 1.55 GHz, tested at 150 MHz, while operating reliably within a temperature range of -55°C to 125°C.

Fixed Inductors Feature Summary

• Utilizes a ceramic drum core for stable RF performance
• Unshielded construction suitable for high-frequency applications
• Surface-mount design optimized for automated assembly

Fixed Inductors Applications

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

Fixed Inductors Procurement Notes

Verify the specific suffix 'EJTS' against official Delta documentation to confirm lead time and packaging details. Ensure compatibility with RoHS3 standards and check moisture sensitivity level requirements before procurement. Confirm that the 0603 footprint matches the target PCB layout dimensions precisely.

Fixed Inductors Selection Notes

Select this component when a compact 0603 form factor is required for 120 nH inductance. Consider the 420 mA current rating and 720 milliohm DCR for power loss calculations. Evaluate the 1.55 GHz self-resonant frequency to ensure it aligns with the target operating bandwidth without parasitic resonance issues.

Fixed Inductors Part Context

This part belongs to the 0603HP series of ceramic RF inductors from Delta Electronics. The series covers inductance values from 1.8 nH to 390 nH, designed for high-frequency applications. The 0603HP series provides various tolerance options and current ratings within the standard 1.60mm x 1.10mm footprint.

Fixed Inductors Replacement Considerations

Cross-reference with other 0603HP variants such as 0603HP-121EGTS for ±2% tolerance or 0603HP-121EJTS if available. Verify physical dimensions and electrical parameters match exactly before substitution.
