1. What are the main features of the SWPA4010S100MT?
The SWPA4010S100MT is a 10 µH shielded drum-core wirewound power inductor designed for stable performance in compact power circuits. It has a maximum DC resistance of 360 mΩ and supports a rated current of up to 750 mA. Its shielded construction helps reduce magnetic interference with nearby components, while the wirewound structure provides reliable inductance and good current-handling capability.
2. What is the SWPA4010S100MT used for?
The SWPA4010S100MT is mainly used for energy storage, filtering, and current smoothing in switching power circuits. Typical applications include DC-DC converters, voltage regulators, power supplies, LED lighting, portable electronics, communication equipment, and other embedded systems. Its compact surface-mount construction makes it suitable for PCB designs where board space is limited.
3. Does the SWPA4010S100MT have alternative manufacturers and part numbers?
Yes. Similar 10 µH shielded power inductors are available from manufacturers such as Murata, TDK, Bourns, Vishay, Würth Elektronik, and Pulse Electronics. However, an alternative should not be selected based only on the 10 µH inductance value. Designers should compare saturation current, rated current, DC resistance, operating temperature, dimensions, inductance tolerance, shielding characteristics, and PCB footprint to ensure proper circuit performance.
4. Is technical support available for the SWPA4010S100MT?
Yes. Sunlord provides technical specifications and product documentation for its SWPA series, including inductance, DC resistance, current ratings, temperature characteristics, and other electrical parameters. These specifications can help engineers determine whether the SWPA4010S100MT is appropriate for a particular power application. When designing with this component, actual operating current, switching frequency, temperature rise, and PCB layout should be carefully evaluated to ensure reliable long-term operation.
