The 660 mOhm max DC resistance sets the copper loss — at 460 mA that's about 140 mW of self-heating, well within the 105°C operating ceiling for a board in a power supply or RF bias line. ## What the 460 mA rating means for your rail The 460 mA current rating and 440 mA saturation current are close — the core starts to saturate just below the thermal limit, so this part is sized for steady-state DC bias rather than high-peak ripple. If your buck converter's inductor current swings above 440 mA during a load transient, the inductance collapses and ripple jumps. Self-resonant frequency is 8 MHz — above that the inductor looks capacitive. Keep the switching frequency of your converter below about 2 MHz to stay clear of the SRF zone. The 1212 (3030 Metric) footprint is a standard 3.00 mm x 3.00 mm body with 1.50 mm seated height — fits the low-profile gap under a mezzanine card or behind a connector. ## Active production, ordered per BOM The ferrite core and wirewound construction are standard for DC-DC input/output filtering, EMI suppression, and low-voltage power rail decoupling where 33 µH at 460 mA fits the load.","metaTitle":"Murata LQH3NPN330MMEL 33 µH Shielded Inductor, 460 mA","metaDescription":"Murata LQH3NPN330MMEL drum core wirewound inductor, 33 µH ±20%, shielded, 460 mA rated, 660 mOhm DCR. 1212 (3030 Metric) package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Inductors & Chokes"],"specifications":{"Mfr":"Murata Electronics","Type":"Drum Core, Wirewound","Series":"LQH3","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"33 µH","Mounting Type":"Surface Mount","Package / Case":"1212 (3030 Metric)","Product Status":"Active","Material - Core":"Ferrite","lifecycle_stage":"unknown","Size / Dimension":"0.118\\\" L x 0.118\\\" W (3.00mm x 3.00mm)","Base Product Number":"LQH3NPN","DC Resistance (DCR)":"660mOhm Max","Current Rating (Amps)":"460 mA","Height - Seated (Max)":"0.059\\\" (1.50mm)","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"1212 (3030 Metric)","Frequency - Self Resonant":"8MHz","Current - Saturation (Isat)":"440mA","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/90c5f07bb626cfbc98c5fc54fd9965f6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does LQH3NPN330MMEL use?","answer":"Surface-mount 1212 (3030 Metric) — 3.00 mm x 3.00 mm body, 1.50 mm seated height.
