106-821F

Overview

The Delevan 106-821F is a fixed RF inductor with an inductance of 820 nH and a tolerance of ±1%. It features a maximum DC resistance of 700 mOhms and a rated current of 380 mA. The component operates within a temperature range of -55°C to +125°C. It utilizes an iron core material and is designed for surface mount PCB installation.

Feature Summary

• Unshielded wirewound construction for general-purpose RF applications
• Iron core material providing stable inductance characteristics
• Surface mount package design for automated PCB assembly

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Procurement Notes

Verify RoHS compliance status as the product may not meet current environmental standards. Confirm lead availability and manufacturing lead times directly with the supplier or authorized distributors, as stock levels fluctuate. Ensure the specific ordering suffix matches the required packaging configuration for production integration.

Selection Notes

Select this component when a compact unshielded inductor with 820 nH nominal value is required. Consider the 380 mA current rating and 700 mOhm DCR for power handling constraints. Verify that the unshielded design does not interfere with nearby sensitive components due to magnetic field emission.

Part Context

This part belongs to the 106 series of fixed inductors from API Delevan. The series offers various inductance values and tolerances tailored for RF and microwave applications. The 106-821F specifically targets designs requiring moderate current handling in a small form factor.

Replacement Considerations

Direct substitutes include the S1008-821H (820 nH, shielded, 715 mA) if higher current capacity is needed. For unshielded alternatives, check the MIL1812-821K series, though it has different electrical parameters. Always verify pin compatibility and thermal performance before substitution.
