1210R-182H

Fixed Inductors Overview

The Delevan 1210R-182H is a surface-mount RF inductor with a nominal inductance of 1.8 µH and a tolerance of ±3%. It features an unshielded wirewound construction on a ferrite core, housed in a 1210 (3225 metric) package measuring 4.83 mm x 3.4 mm x 3.4 mm. The component has a maximum DC resistance of 650 mOhms and supports a maximum DC current of 556 mA. It operates within a temperature range of -55°C to +125°C, exhibits a minimum Q factor of 50 at 7.9 MHz, and reaches a self-resonant frequency of 60 MHz.

Fixed Inductors Feature Summary

• Unshielded wirewound design for specific RF applications
• Ferrite core construction for stable inductance
• Surface-mount compatibility with standard SMD/SMT termination

Fixed Inductors Applications

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

Fixed Inductors Procurement Notes

Verify the exact datasheet specifications before procurement, as distributor listings may vary between shielded and unshielded variants or conflicting DCR values. Confirm availability status directly with authorized suppliers, as stock levels are reported as limited or out of stock across multiple channels. Ensure the ordering suffix matches the required tolerance and shielding configuration for your specific design requirements.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is required to minimize parasitic coupling effects in sensitive RF layouts. The 1210 footprint offers a balance between current handling and board space. Compare against shielded alternatives if magnetic interference suppression is necessary, noting that unshielded versions typically offer different self-resonant characteristics.

Fixed Inductors Part Context

This part belongs to the 1812/R series of fixed inductors from Delevan. While the model number indicates a 1210 footprint, it shares design lineage with other series like the S1210R. It serves as a specialized passive component distinct from power inductors, focusing on high-frequency performance rather than high-current power delivery.
