0402HM-190EJTS

Fixed Inductors Overview

The Delta Electronics/Components 0402HM-190EJTS is a fixed wirewound inductor with a nominal inductance of 19 nH and a tolerance of ±5%. It features an unshielded drum core design using ceramic material, housed in a compact 0402 (1005 Metric) surface-mount package measuring 1.15mm x 0.70mm x 0.60mm max. The component has a DC resistance of 270 mOhm and a rated current of 370 mA. It exhibits a self-resonant frequency of 4.5 GHz and a Q value of 25 at 250 MHz. Operating temperature range spans from -55°C to 125°C.

Fixed Inductors Feature Summary

• Unshielded drum core wirewound construction for high-frequency signal integrity
• Compact 0402 footprint suitable for dense surface-mount layouts
• High self-resonant frequency of 4.5 GHz for RF applications
• Wide operating temperature range from -55°C to 125°C

Fixed Inductors Applications

• RF matching networks
• High-frequency filtering circuits
• Impedance matching in wireless communication modules

Fixed Inductors Procurement Notes

Verify the ordering suffix 'J' confirms the ±5% tolerance specification against official datasheets. Ensure compatibility with standard reflow soldering profiles for 0402 components. Confirm RoHS3 compliance status if required by specific regulatory frameworks. Check manufacturer lead times as availability may vary.

Fixed Inductors Selection Notes

Select this component when a precise 19 nH inductance with tight ±5% tolerance is required in minimal space. Consider the 370 mA current rating and 270 mOhm DCR for power handling needs. The 4.5 GHz SRF makes it suitable for frequencies below this limit. Compare against 0402HM-190EGTS if tighter ±2% tolerance is needed, noting the change in suffix.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors from Delta Electronics/Components. The series utilizes ceramic drum cores and wirewound technology. It shares the same physical dimensions and mounting style with other variants in the series, differing primarily in inductance values and tolerance specifications defined by their respective ordering suffixes.

Fixed Inductors Replacement Considerations

0402HM-190EGTS offers identical electrical parameters except for a tighter ±2% tolerance instead of ±5%. Verify that the application circuit can accommodate the slight variance in tolerance if substituting between J and E suffixes.
