The ±5% tolerance holds the inductance tight enough for most DC-DC input/output filters and signal conditioning where you care about the value more than the absolute saturation floor. ## AEC-Q200 and 125°C ceiling — where it lives on the board The ferrite core holds its inductance across that band better than a powdered-iron core would, though the DCR will climb with temperature — budget the 168 mOhm max at 25°C and derate for your actual junction temp. Self-resonant frequency is 60 MHz, Q factor is 20 at 1 MHz. That SRF tells you the inductor stops looking inductive above roughly 60 MHz — fine for a switching regulator switching at a few hundred kHz to a couple MHz, but not the part for a 100 MHz RF bias tee. The Q at 1 MHz is modest; this is a power/decoupling inductor, not a high-Q tank component.","metaTitle":"Murata LQH32NH3R9J23L Drum Core Wirewound Inductor, 3.9 µH","metaDescription":"Murata LQH32NH3R9J23L drum core wirewound inductor, 3.9 µH ±5%, 510 mA, 168 mOhm DCR, AEC-Q200, -40°C to +125°C, 1210 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":"LQH32","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"AEC-Q200","Features":"-","Q @ Freq":"20 @ 1MHz","Shielding":"Unshielded","Tolerance":"±5%","Inductance":"3.9 µH","Mounting Type":"Surface Mount","Package / Case":"Nonstandard","Product Status":"Active","Material - Core":"Ferrite","lifecycle_stage":"unknown","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Base Product Number":"LQH32NH","DC Resistance (DCR)":"168mOhm Max","Current Rating (Amps)":"510 mA","Height - Seated (Max)":"0.087\\\" (2.20mm)","Operating Temperature":"-40°C~125°C","Supplier Device Package":"1210 (3225 Metric)","Frequency - Self Resonant":"60MHz","Current - Saturation (Isat)":"-","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/57ddb57aecf586c7dc125b88e96a3c0d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LQH32NH3R9J23L AEC-Q200 qualified?","answer":"Yes, it carries an AEC-Q200 rating, meaning it has passed the automotive-grade passive component stress tests (temperature cycling, moisture resistance, mechanical shock/vibration, solder heat).
