1 µH shielded wirewound for DC-DC filtering
The LQH2MPN1R0NGRL: Rated for 900 mA continuous current with a 300 mOhm max DCR, the DC resistance sets the I²R thermal budget — at full rated current the self-heating is roughly 243 mW, well within the 105°C operating ceiling. The saturation current of 1.55 A defines the hard ceiling where the ferrite core saturates and inductance collapses — derate to stay below this in peak-current applications like buck converter output stages.
Frequency response and board fit
Self-resonant frequency of 100 MHz marks the upper usable band — above SRF the inductor behaves capacitively, so this part suits DC-DC converters switching in the 1–10 MHz range where the 1 µH value and SRF provide adequate filtering margin. The 0806 footprint (2.00 mm × 1.60 mm) with 0.95 mm seated height fits dense PCB layouts common in portable and space-constrained designs, and the shielded construction minimises radiated EMI coupling to adjacent traces. Inductance is tested at 1 MHz per the datasheet condition — the ±30% tolerance is wide, so confirm the minimum inductance at your operating current using the vendor's bias curves if the application is frequency-sensitive.
