SPB-300: 40µH @ 12.0ADC Inductor

The first in our SPB-300 series, this 100% tested switch mode power inductor has ratings of 40µH at 12.0ADC, equating to a maximum DCR of 0.013 Ω.

The SPB-300 is a truly versatile non-shielded inductor, and can be found in a wide range of products in both household and industrial settings. Its small size and low weight are key benefits, particularly where product size and weight are major design considerations of the final product.

The purpose of the SPB-300 is to filter the output waveform signals of switching supply circuits, and it can be found in the following battery or alternating current (AC) line voltage powered applications:

  • Welders
  • Microwave ovens
  • Printers
  • Hand-held LED lights
  • Air cleaning equipment
  • Sonobuoy power amplifiers

The ferrite bobbin core found in this inductor is key to its success. The ferrite core provides exceptional stability and is coated in epoxy paint. Its leads are tinned to within 0.063" [1.6mm] of the core.

Additional dimensional information includes:

  • Lead size: 14 AWG.
  • Core Diameter: 0.955” / 24.26 mm.
  • Core Height: 0.975” / 24.77 mm.
  • Center-to-center dimension of radial Leads: 0.775 inches / 19.69 mm.
  • Radial leads extend 0.6875” / 17.46 mm to 0.8125” / 20.64 mm from the mounting core surface.

If you need to secure this inductor even more, use a non-metallic #4 screw and the through-hole designed for mounting the inductor to the printed circuit board.
