1206HS-122EKTS

Overview

The 1206HS-122EKTS is a fixed surface-mount inductor from Delta Electronics/Components, designed for high-frequency applications. It features an unshielded drum core wirewound construction with a ceramic magnetic core. The component provides an inductance of 1.2 µH with a tolerance of ±10%. It supports a rated current of 300 mA and exhibits a DC resistance of 3.2 Ohms. Key electrical parameters include a self-resonant frequency of 380 MHz and a test frequency of 35 MHz. The device operates within a temperature range of -40°C to 125°C and is available in a standard 1206 (3216 Metric) package.

Feature Summary

• Unshielded drum core wirewound design utilizing ceramic magnetic material for stable RF performance
• Surface mount configuration optimized for automated assembly processes
• Wide operating temperature range suitable for demanding environmental conditions

Applications

• RF circuit filtering
• High-frequency signal processing
• Power supply output chokes

Procurement Notes

Verify the specific suffix EKTS against official Delta documentation to confirm packaging and tape specifications. Ensure compatibility with standard SMT reflow profiles. Confirm RoHS compliance status through the latest manufacturer datasheet before integration into production lines.

Selection Notes

Select this component when a 1.2 µH inductance value is required with a 300 mA current rating. The 1206 footprint offers a balance between size and power handling. Consider the 380 MHz self-resonant limit for high-frequency designs to ensure effective operation above the test frequency.

Part Context

This part belongs to the HS series of fixed inductors manufactured by Delta Electronics/Components. The series utilizes ceramic cores and wirewound techniques to achieve consistent inductance values. The 1206HS variant specifically targets surface-mount applications requiring reliable performance in compact electronic assemblies.

Replacement Considerations

Consult official Delta Electronics cross-reference lists for verified substitutes. Direct replacements must match the 1.2 µH inductance, 300 mA rating, and 1206 package dimensions. Verify that alternative components maintain similar self-resonant frequencies and DC resistance characteristics.
