Procurement Notes

Verify the specific ordering suffix against official Delta Electronics documentation to ensure correct tolerance and packaging specifications. Confirm that the requested quantity aligns with manufacturer standard pack sizes, typically provided in tape and reel formats. Cross-reference the DigiKey part number 2035-1170-2-ND for accurate distributor identification and stock availability status prior to finalizing procurement orders.

Selection Notes

Select this component when a low inductance value near 10 nH is required for high-frequency applications. The 1008 package size offers a balance between current handling capacity and board space constraints. Ensure the operating environment remains within the specified -40°C to 125°C range. Consider the unshielded nature of the design regarding potential electromagnetic interference coupling with adjacent sensitive traces on the printed circuit board layout.

Part Context

This part belongs to the 1008CS series of wire-wound chip inductors manufactured by Delta Electronics. The series utilizes ceramic cores and open-type construction to achieve high self-resonant frequencies suitable for RF and microwave applications. The 1008CS-100EJTS specifically denotes the 10 nH variant within this family, sharing common mechanical dimensions and thermal characteristics with other values in the same series.

Replacement Considerations

Direct substitutes include other 10 nH, 1 A, 1008 package inductors from different manufacturers such as Murata or TDK, provided they meet the same electrical parameters and physical footprint requirements. Verify that alternative parts maintain comparable self-resonant frequencies and Q values to ensure equivalent high-frequency performance in the target application circuit.
