Last-buy inductor — what the ratings mean for fit
The LQH31MN560K03L: It is rated for 50 mA DC current with a maximum DC resistance of 11.57 Ohm — the DCR figure sets the I²R loss floor at that current, so the voltage drop across the part at full rated current is roughly 0.58 V.
Parametric profile for signal-path filtering
Self-resonant frequency is 9 MHz, and Q factor is 40 at 2.5 MHz — the useful filtering band sits below SRF, so this part is suited for low-frequency noise suppression and decoupling in the kHz to low-MHz range, not for RF bypass above 9 MHz.
Last-buy status and sourcing posture
Murata lists the LQH31MN560K03L as Last Buy — the manufacturer has announced end-of-life and this is the final procurement window. Sourced through independent distribution channels; quantities and pricing are confirmed at RFQ.
