1008CS-121EGTS

Overview

The Delta Electronics 1008CS-121EGTS is a fixed surface-mount inductor with 120 nH nominal inductance and ±2% tolerance. It utilizes an unshielded drum core wirewound design on a ceramic substrate, housed in a 1008 (2520 metric) package measuring 2.92mm x 2.79mm x 2.03mm. The component supports a rated current of 650 mA with a maximum DC resistance of 630 mΩ. It exhibits a self-resonant frequency of 950 MHz and a Q factor of 60 at 350 MHz, operating reliably within a temperature range of -40°C to 125°C.

Feature Summary

• Unshielded drum core wirewound construction for high-frequency RF applications
• High precision ±2% inductance tolerance for tight circuit requirements
• Ceramic core material ensuring stable thermal performance

Applications

• RF matching networks
• High-frequency filtering circuits
• Impedance matching stages

Procurement Notes

Verify the specific suffix EGTS against official Delta Electronics documentation to confirm the exact electrical parameters, particularly the 650 mA rating and 630 mΩ DCR. Ensure the ordering code matches the required ±2% tolerance and 1008 package dimensions. Confirm RoHS3 compliance status directly from the manufacturer's latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when precise 120 nH inductance is required for RF signal paths. The unshielded design necessitates careful PCB layout to minimize electromagnetic interference with adjacent traces. Verify that the 650 mA current rating exceeds the peak operational current of the target circuit to prevent saturation or thermal issues during continuous operation.

Part Context

This part belongs to the Delta Electronics 1008CS series of ceramic RF inductors. The series offers various inductance values ranging from 4.7 nH to 15 µH in the 1008 footprint. These components are engineered for high-Q performance in wireless communication devices and mobile electronics requiring compact, high-stability passive components.

Replacement Considerations

Cross-reference with other manufacturers offering 1008 footprint unshielded wirewound inductors with 120 nH ±2% tolerance. Verify that substitute parts match the 630 mΩ DCR limit and 950 MHz self-resonant frequency specifications to maintain circuit integrity.
