The 4.7 µH ±20% inductance and 1.6 A continuous current rating make it a candidate for buck-converter output filters and point-of-load rails where the DC current stays under the saturation ceiling of 2.3 A. The 157 mOhm max DCR sets the I²R conduction loss — at 1.6 A that's roughly 0.4 W, which the metal-core construction and -40 to +125 °C operating range can handle in most ambient conditions without forced airflow. ## Saturation headroom and thermal margin Isat is specified at 2.3 A, giving about 44 % headroom above the rated 1.6 A. For a buck converter with a 30 % inductor current ripple, the peak current hits roughly 1.85 A at full load — still 20 % below saturation, so inductance holds within tolerance across the load step. Inductance is tested at 1 MHz, which is typical for the switching frequencies of mid-power DC-DC converters in the 500 kHz to 2 MHz range. The metal-alloy core material keeps core losses manageable at those frequencies compared to ferrite. Volume pricing and lead time are confirmed per RFQ — no stock-holding claim, sourced through authorized and independent channels.","metaTitle":"Murata DFE322512F-4R7M=P2 Shielded Power Inductor, 4.7 µH","metaDescription":"Murata DFE322512F-4R7M=P2 shielded wirewound inductor, 4.7 µH ±20%, 1.6 A rated, 2.3 A saturation, 157 mOhm DCR. 1210 footprint, -40 to +125 °C.","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":"DFE322512F","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"-","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"4.7 µH","Mounting Type":"Surface Mount","Package / Case":"1210 (3225 Metric)","Product Status":"Active","Material - Core":"Metal","lifecycle_stage":"unknown","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Base Product Number":"DFE322512F","DC Resistance (DCR)":"157mOhm Max","Current Rating (Amps)":"1.6 A","Height - Seated (Max)":"0.047\\\" (1.20mm)","Operating Temperature":"-40°C~125°C","Supplier Device Package":"1210","Frequency - Self Resonant":"-","Current - Saturation (Isat)":"2.3A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d7b56d80319ca175368b796c3c339c0c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current and why does it matter for this inductor?","answer":"The saturation current (Isat) is 2.3 A.
