1206HS-270EJTS

Overview

The 1206HS-270EJTS is a fixed wirewound inductor from Delta Electronics/Components, designed for surface mount applications. It features an unshielded drum core construction with a ceramic magnetic core material. The component provides an inductance of 27 nH with a tolerance of ±5%. It supports a rated current of 1 A and exhibits a DC resistance (DCR) of 110 mOhm. The self-resonant frequency is specified at 2.45 GHz, with Q value testing conducted at 500 MHz. The device operates within a temperature range of -40°C to 125°C and conforms to RoHS3 standards.

Feature Summary

• Unshielded drum core wirewound design for minimal electromagnetic interference impact
• High self-resonant frequency capability suitable for RF signal paths
• Robust current handling with 1 A rated current capacity
• Low DC resistance for efficient power transmission

Applications

• RF filter circuits in wireless communication modules
• Impedance matching networks in high-frequency transceivers
• Power supply filtering in compact electronic devices
• Signal conditioning in mobile phone antenna systems

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variations may exist between tape-and-reel and cut-tape formats. Confirm that the selected variant matches the required RoHS3 compliance status for environmental regulations. Cross-reference the manufacturer part number against official distributor databases to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a low-inductance value near 27 nH is required for high-frequency operation. Ensure the PCB footprint accommodates the 1206 (3216 Metric) package dimensions. Consider the 1 A current rating to prevent saturation under peak load conditions. Verify that the unshielded nature aligns with the circuit's EMI requirements and spatial constraints.

Part Context

This inductor belongs to the HS series of fixed inductors from Delta Electronics/Components, characterized by high-current capabilities and small form factors. The series utilizes ceramic cores to maintain stability across varying temperatures. It serves as a passive component in modern electronics where space efficiency and performance at GHz frequencies are critical design parameters.

Replacement Considerations

Public confirmed substitute: 0805CT-270EJTS. Note that this alternative uses a smaller 0805 package and has a lower rated current of 600 mA compared to the 1 A rating of the 1206HS-270EJTS. Ensure the reduced current capacity and different physical footprint are acceptable for the application.
