Overview
The Delevan 106-122J is a fixed surface-mount RF inductor with a nominal inductance of 1.2 µH and a tolerance of ±5%. It features an unshielded wirewound construction on an iron core, resulting in a maximum DC resistance of 0.9 Ω. The component supports a maximum current rating of 335 mA and operates within a temperature range of -55 °C to +125 °C.
Feature Summary
- Unshielded wirewound design suitable for general-purpose RF applications
- Iron core construction providing stable inductance characteristics
- Surface-mount technology (SMT) package for automated assembly
Applications
- RF signal processing circuits
- General-purpose filtering networks
- Impedance matching stages
Procurement Notes
Verify compliance requirements as the 106-122J is explicitly identified as lead-containing and non-RoHS compliant in official documentation. Confirm that target markets permit lead-based components. Ensure the unshielded topology aligns with electromagnetic interference constraints for the specific application environment before finalizing procurement.
Selection Notes
Select this component when a 1.2 µH value with tight 5% tolerance is required for RF frequencies. The 0.9 Ω DC resistance limits current handling to 335 mA, making it unsuitable for high-power power supply filtering. Consider the unshielded nature regarding nearby magnetic sensitivity and layout spacing requirements.
Part Context
This part belongs to the API Delevan 106 series of fixed inductors. It is distinct from shielded variants or higher-current power inductors like the P1330R series. The 106 series utilizes iron cores, differentiating it from ferrite-core alternatives in terms of saturation behavior and frequency response characteristics.
Replacement Considerations
Direct substitutes must match the 1.2 µH inductance, 5% tolerance, and 0.9 Ω DC resistance. Verify that replacement parts accommodate the same SMT footprint and thermal ratings. Note that shielded alternatives may alter parasitic capacitance and self-resonant frequency performance.
