A high-quality switch mode power supply inductor, the SPB-307 is part of our bestselling SPB-300 range, offering a small size, light weight solution essential to countless applications. Also known as a filter inductor, the SPB-307 is capable of filtering the output waveform signals of switching supply circuits. The SPB-307 has an inductance rating of 300µH @ 5.5ADC, and is fit for a wide range of purposes. Inductors like the SPB-307 can be used:
- In household products and appliances, including microwave ovens.
- In tools and equipment, including welders.
- In industrial settings, including in air cleaning equipment.
- By the US Navy, in sonobouy power amplifiers.
- In countless additional applications, in battery and AC line voltage powered applications, as well as in rectified and filtered circuits.
There are many reasons to make the SPB-307 your first choice switch mode power supply inductor. Crafted by our expert team, the SPB-307 is 100% tested for dependability. This particular filter inductor benefits from a ferrite bobbin core, providing inductance stability. To ensure durability, the core has been coated in epoxy paint. The SPB-307 is equipped with a centrally located through-hole, so that it count be mounted to the printed circuit board with a non-metallic #4 screw.
This open frame inductor has a core diameter of 0.955” / 24.26 mm and a core height of 0.975” / 24.77 mm, with a lead size of 18 AWG. The center-to-center dimension of the radial leads is 0.775 inches / 19.69 mm. They extend 0.6875” / 17.46 mm to 0.8125” / 20.64 mm from the mounting core surface and are tinned to within 0.063” / 1.6 mm from where they exit the core.
