Overview of HCCI-80 Series Power Inductors
The HCCI-80 Series of surface-mount power inductors is designed by TECHNITRONIX COMPANY for a wide array of applications requiring a high current rating and efficient inductance. Compliant with RoHS standards, these inductors offer a footprint of 31.0mm x 25.4mm max and a height of 12.7mm max. Available inductance values range from 1.1pH to 18.1pH, with current ratings up to 38A.
Electrical Specifications and Features
Operating within a temperature range of -40°C to +130°C, the HCCI-80 Series displays a variety of inductance values coupled with their specific parameters including rated current (Irated), DC resistance (DCR), inductance tolerance, and efficiency factors such as flux density, core loss, and temperature rise. Core losses can be mathematically estimated using formulae provided which take into consideration the inductor’s frequency and voltage-time product. Moreover, the series’ parallel or series connection types offer further customization for specific circuit requirements.
Part Numbering and Options
Each inductor within the series is assigned a unique part number (e.g., POS99NL), aiding in easy identification. The suffix ‘NL’ indicates that the part is RoHS-compliant. An additional ‘T’ suffix denotes optional Tape & Reel packaging which aligns with EIA481 standard.
Usage Notes and Recommendations
The HCCI-80 Series inductors are typically applied within circuits operating at 300kHz with the rated current, and a temperature rise of 55°C is expected. Total loss is noted to be around 1.8W for the specified temperature rise. To manage higher core losses in applications with extensive volt-time, current derating may be considered to limit temperature elevation. It’s critical to assure that the component’s overall temperature remains inside the specified operating range.
Mechanical and Packaging Details
The inductors weigh 18.7 grams and are offered in Tape & Reel packaging with 75 units per reel, or Tube packaging with 20 units per tube. The datasheet includes a suggested pad layout and clear dimensions in both inches and millimeters, ensuring ease of integration into various PCB assemblies. Additionally, contact details for international support from Pulse locations are provided.
