Overview
The 4000 series datasheet provides information on a range of toroidal surface mount inductors designed by C&D Technologies. Suitable for integration into switching power supplies and DC/DC converters, this series stands out due to its compatibility with low profile and compact surface mount packaging requirements. Its primary application lies in power management within electrical circuitry, where space optimization and efficiency are paramount.
Features
The inductors are characterized by an inductance range of 3.3pH to 330pH and are built for surface mounting, handling up to 5.20A DC Current Continuous (IDC). They are constructed with UL 94V-0 package materials and possess a toroidal design, which minimizes leakage flux. Additionally, the inductors are pick & place compatible, facilitating easy assembly during the manufacturing process. The series is presented as being highly efficient for space-sensitive applications due to their compact size.
Selection Guide and Electrical Specifications
The selection guide portion of the datasheet lists a variety of part numbers alongside their corresponding nominal inductance values, spanning from 3.3 pH to 330 pH, measured at 10kHz, 1 OmV. Each specified inductor also has an inductance range at the same frequency and voltage, detailing the minimum and maximum inductance values. Additionally, the guide includes the maximum DC resistance in milliohms and the maximum rated DC current continuous the inductor can handle without overheating.
Package Details
The datasheet defines the package type as tube with a typical weight for each part listed as 3.2g and the standard quantity as 30 units per tube. Detailed mechanical dimensions are provided in both inches and millimeters to ensure precise board layout and footprint matching for the secure mounting of the components.
Maximum Ratings and Standards Compliance
These inductors operate within an ambient temperature range of -40°C to 85°C and can be stored between -40°C and 125°C. They meet the RoHS compliance specified by the directive 2002/95/EC, thereby adhering to restrictions on the use of certain hazardous substances in electrical and electronic equipment.
