MHL1ECTTP18NJ

Overview

The MHL1ECTTP18NJ is a fixed multilayer RF inductor from the KOA Speer MHL series, designed for surface-mount applications. It features an unshielded construction within a compact 0402 (1005 metric) package measuring 1.0 mm x 0.5 mm x 0.60 mm. The component provides an inductance of 18 nH with a tolerance of ±5%. It supports a maximum DC current of 300 mA and exhibits a maximum DC resistance of 650 mOhms. The self-resonant frequency reaches 2 GHz, with a Q factor of 8 at 100 MHz. Operating temperatures range from -55°C to +125°C.

Feature Summary

Unshielded multilayer ceramic construction optimized for high-frequency RF signal integrity
Compact 0402 footprint enabling dense PCB layout for wireless communication modules
High self-resonant frequency capability supporting ultra-high frequency circuit designs

Applications

RF matching networks in wireless communication devices
