The provided datasheet outlines the specifications, features, and ordering information for Coilcraft’s Mini Air Core Inductors. These inductors are designed for environments with an operating temperature range of -40°C to +140°C and are compliant with RoHS and REACH standards. Additionally, they meet the AEC Q200 standard, which qualifies them for automotive applications.
Key Features
These inductors have a high Q factor and are made with tight tolerances for precision use. An acrylic jacket gives the components a flat top suitable for pick and place operations. Their solder coated leads are meant to secure a reliable soldering process.
Environmental and Mechanical Specifications
The inductors can handle temperature extremes, from the ambient operating range between -40°C to +125°C, to a higher range of +125°C to +140°C with a derated current. When not in operation, the component itself can withstand storage temperatures of -40°C to +140°C, while the tape and reel packaging can tolerate -40°C to +80°C.
Resisting soldering heat is ensured by the ability to withstand up to three 40-second reflows at +260°C, provided that the parts are allowed to cool to room temperature between cycles. Additionally, the inductors have a Temperature Coefficient of Inductance (TCL) of +5 to +70 ppm/°C and a Moisture Sensitivity Level (MSL) indicating unlimited floor life at <30°C and 85% relative humidity.
Packaging and Handling
The inductors are available on 7″ or 13″ reels, with the packaging material differing slightly in width and thickness between the AOxT and BxxT series. Specific packaging information provided includes the pocket spacing and depth, along with recommendations for pick and place nozzle size. These inductors are also tested according to MIL-STD-202 Method 215 with an additional aqueous wash for PCB suitability.
Electrical Specifications
Individual part numbers, along with their corresponding inductance values, Q factors, Self-Resonant Frequency (SRF), Direct Current Resistance (DCR), and current ratings (Irms), are detailed in a table format. For example, the AO1TKL part has 2.5 turns with a 10% tolerance, resulting in an inductance of 145 nH and an SRF of 12.5 GHz. Moreover, the weight and dimensions for each part are listed.
Ordering Information
Customers are advised to specify tolerance, termination, and packaging codes when ordering. Tolerance tiers, termination types (RoHS compliant tin-silver or non-RoHS tin-lead), and packaging options are described. It is noted that Coilcraft is streamlining packaging codes; hence, customers must change the last letter of their part number accordingly.
Note that the listed electrical specifications are measured at 25°C, and physical dimensions are provided in millimeters, with a reference guide for soldering surface mount components also mentioned (Doc 362).
Contact information for Coilcraft sales offices in different regions, including the US, UK, Taiwan, China, and Singapore, are provided. The document concludes by reinforcing the need for Coilcraft approval for any medical or high-risk applications and includes a disclaimer that specifications are subject to change.
