Product catalog summary
Overview: The document provides technical specifications for the LWF Series Ferrite Wirewound Inductors by Stackpole Electronics, Inc., detailing various models, their specifications, and applications.
Specifications:
  • Inductance and Current Ranges: Models such as LWF0603, LWF0805, LWF1008, LWF1210, LWF1812, and LWF2220 are listed with specific inductance (μH) and current ranges (mA).
  • Mechanical Specifications: Dimensions and weights are provided in inches and millimeters for different models.
  • Electrical Specifications: Each model's electrical characteristics include inductance, Q factor, test frequency, self-resonant frequency (SRF), direct current resistance (DCR), and maximum current (IDC).
Features:
  • Wirewound on ferrite core design ensures high reliability under stress.
  • Robust termination for mechanical strength and high Q values in small packages.
  • High current options are available.
Applications:
  • Suitable for micro televisions, liquid crystal televisions, video cameras, car radios, and other electronic devices.
Key Data from Tables:
  • Part numbers are linked to specific tolerance levels, inductance values, and electrical characteristics like Q factor and DCR.
  • Models such as LWF0603 and LWF0805 offer high current (HC) and low profile (LP) options.
Packaging: Inductors are packaged in embossed plastic tape with a cover tape peel strength of 0.1~0.6 N under specified conditions.
Ordering Information: A coding system is used for ordering, indicating product series, size, tolerance, inductance, and packaging.
Recommendations:
  • Confirm technical specifications before ordering or using the products, as they may change without notice.
  • Contact Stackpole for additional inductance values if needed.
