# MPL-AY1265-2R2 (Component) ## Description 2.2µH Unshielded Molded Inductor 17 A 3.7mOhm 2-SMD, J-Lead The MPL-AY1265-2R2 is a 2.2 µH surface-mount molded power inductor from Monolithic Power Systems (MPS). It is designed for high-current DC-DC switching power supplies and power management applications requiring low DC resistance (DCR), high efficiency, and stable inductance over a wide operating temperature range. Its molded construction minimizes audible noise and provides excellent mechanical reliability for compact, high-performance electronic designs. Key Features 2.2 µH inductance with ±20% tolerance High rated current: up to 17 A Low DC resistance: 3.7 mΩ typ. (4.3 mΩ max.) Soft saturation characteristics for improved reliability Molded construction for enhanced durability and reduced EMI Low audible noise during switching operation Stable performance across a wide temperature range Operating temperature: −40°C to +155°C Compact SMD package: 13.5 × 12.6 × 6.2 mm RoHS/REACH compliant and halogen-free Typical Applications Battery-powered devices Portable electronics Embedded computing systems High-current switching mode power supplies (SMPS) High-frequency DC-DC converters Point-of-load (POL) converters FPGA power rails #MoldedInductor #PowerInductor #2_2uH #HighCurrent #LowDCR #SMPS #DCDCConverter #PowerManagement #SMD #MonolithicPowerSystems #RoHS #EmbeddedSystems ## Component Details - **Owner:** adrian95 - **Created:** 6/28/2026 - **Last Updated:** 6/28/2026 - **Visibility:** Public - **Datasheet URL:** https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/9567c42aac7ebd6768c4b67bc5432a8690ede78865d3f3cfd4d022de4d37f020.pdf - **Inductance:** 2.2µH - **Package or Case Code:** 2-SMD, J-Lead - **Manufacturer Name:** Monolithic Power Systems Inc. - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Part Number:** MPL-AY1265-2R2 - **Part Type:** Inductor ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
