AIAC-0805C-18NK-T

Overview

The AIAC-0805C-18NK-T is an unshielded wirewound RF inductor from Abracon LLC, housed in a standard 0805 surface-mount package. It features a ceramic core and provides a nominal inductance of 18 nH with a tolerance of ±10%. The component is rated for a maximum DC current of 500 mA and exhibits a maximum DC resistance of 12.5 mOhm. Designed for high-frequency applications, it offers low insertion loss and stable performance across the operating temperature range.

Feature Summary

• Unshielded wirewound construction suitable for general RF signal paths
• Low DC resistance minimizes power loss in high-current circuits
• Compact 0805 footprint enables dense PCB layout integration
• High self-resonant frequency supports ultra-high frequency operation

Applications

• RF matching networks in wireless communication modules
• Impedance matching stages in mobile device antenna systems
• Filtering components in broadband network equipment
• Signal conditioning in Bluetooth and Wi-Fi transceivers

Procurement Notes

Verify the specific suffix 'C' against the manufacturer's latest datasheet to confirm material composition and termination plating specifications. Ensure the selected variant matches the required 18 nH tolerance and current rating for your circuit design. Cross-reference the RoHS compliance status with current environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when a compact, unshielded inductor is required for frequencies where parasitic capacitance must be minimized. The 500 mA current rating suits moderate power RF applications. Compare the 12.5 mOhm DCR against circuit efficiency requirements. Consider shielding needs; if EMI isolation is critical, a shielded alternative from the same series may be necessary.

Part Context

This part belongs to Abracon's AIAC-0805C series of fixed RF inductors. The series utilizes wirewound technology on ceramic cores to achieve high Q factors at VHF/UHF bands. The 0805 case size balances performance with space constraints common in modern consumer electronics and telecommunications hardware.

Replacement Considerations

Direct substitutes include other 18 nH ±10% unshielded wirewound inductors in 0805 packages with similar current ratings. Verify that replacement parts maintain comparable self-resonant frequencies and DC resistance values to ensure circuit stability.
