LanTu Micro SMS0650 R68MT ultra high current power inductor for PDAs notebooks and server applications
Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0650 Series Ultra-high current SMD power inductors are designed for high-density installation and offer a thin profile with low DC resistance and ultra-high current capabilities. Featuring magnetic shielding for strong anti-electromagnetic interference, these inductors provide high reliability through an integral construction for excellent vibration resistance. Their composite structure minimizes buzz noise, while the low-loss alloy powder die-casting ensures low impedance and small parasitic capacitance, contributing to high efficiency. Suitable for applications like PDAs, notebooks, desktop and server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems, these inductors operate at frequencies up to 3MHz and have an absolute maximum voltage of 30VDC. They comply with RoHS, Halogen Free, and REACH standards.

Inductance Tolerance Codes: J:5%, K: 10%, L: 15%, M: 20%, P: 25%, N: 30%
Packing: B (Bulk Package), T (Tape & Reel)
Test Equipment:
- Inductance (L): WK3260B LCR meter or equivalent
- Saturation Current (Isat) & Heat Rating Current (Irms): WK3260B+WK3265B or equivalent
- DC Resistance (DCR): Chroma 16502 or equivalent
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, as it is affected by circuit design, component, PCB trace size and thickness, airflow, and other cooling provisions.
