0603CS-820EJTS

Fixed Inductors Overview

The Delta Electronics/Components 0603CS-820EJTS is an unshielded, drum core, wirewound RF inductor designed for surface mount applications. It features a nominal inductance of 82 nH with a tolerance of ±5%. The component operates within a frequency range up to a self-resonant frequency of 1.7 GHz and maintains a Q factor of 34 at 150 MHz. It supports a rated current of 400 mA and exhibits a DC resistance of 540 mOhm. Housed in a compact 0603 (1608 Metric) package measuring 1.60mm x 0.80mm with a maximum height of 1.02mm, it functions reliably across a temperature range of -40°C to +125°C.

Fixed Inductors Feature Summary

• Utilizes a ceramic drum core and wirewound construction for stable RF performance
• Provides high self-resonant frequency characteristics suitable for RF circuits
• Offers low DC resistance to minimize power loss in signal paths

Fixed Inductors Applications

• RF matching networks
• High-frequency filtering circuits
• Impedance matching stages in communication devices

Fixed Inductors Procurement Notes

Verify the manufacturer designation carefully, as distribution listings may attribute this part to Cyntec or Delta Electronics/Components due to corporate history. Confirm the specific suffix EJTS matches the required tolerance and packaging format. Ensure that the 0603 footprint dimensions align with your PCB layout constraints before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a small form factor is required for RF applications operating near 150 MHz. The 82 nH value and 400 mA current rating suit moderate power signal lines. Consider the 540 mOhm DCR impact on insertion loss. Compare against the 0805CT series if higher current handling or lower resistance is necessary for the design.

Fixed Inductors Part Context

This inductor belongs to the 0603CS series of fixed RF inductors from Delta Electronics/Components. The series provides various inductance values in a standard 0603 package. The 820 code denotes the 82 nH value. This series is engineered for general-purpose RF filtering and impedance matching in consumer electronics and wireless modules requiring compact passive components.

Fixed Inductors Replacement Considerations

Direct substitutes include other 82 nH ±5% inductors in the 0603 package with comparable current ratings. Verify that alternative parts meet the 1.7 GHz self-resonant frequency requirement. Check if competitor components offer similar Q factors at 150 MHz to ensure equivalent circuit performance without redesigning the layout.
