Low DC Resistance Molding SMD Power Inductor LanTu Micro SMS0650-2R2MT for High Density Installations
Molding SMD Power Inductors - SMS0650 Series
Product Overview: SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. presents the SMS0650 Series, a line of ultra-high current SMD power inductors designed for demanding applications. These thin-profile inductors feature low DC resistance and high current handling capabilities, making them ideal for high-density installations. Their magnetic shielding provides strong anti-electromagnetic interference, while the integral construction ensures high reliability and excellent vibration resistance. The composite structure minimizes buzz noise, and the use of low-loss alloy powder in die-casting results in low impedance, small parasitic capacitance, high efficiency, and reduced eddy-current loss. These inductors operate at frequencies up to 3MHz and are RoHS, Halogen Free, and REACH compliant.
Applications: PDA, notebook, desktop, server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.

- DC Resistance (DCR): Chroma 16502 or equivalent
Product Identification:
SMS 0650 - [Inductance] M T
- Inductance: e.g., 100 for 10 H
- Tolerance: M = 20% (Other tolerances: J:5%, K: 10%, L: 15%, P: 25%, N: 30%)
- Type: T = Tape & Reel, B = Bulk Package
- External Dimensions (LWH) (mm): 0650 (7.16.65.0)
Definitions:
- Saturation Current: DC current at which inductance drops 30% from its value without current.
- Heat Rating Current: The actual value of DC current when the temperature rise is T 40 (Ta=25).
- Rated DC Current: The lesser value of Isat or Irms.
Note: Part temperature should be verified in the end application due to the influence of circuit design, component, PCB trace size and thickness, airflow, and other cooling provisions.
