Frequently Asked Questions
What DCR and inductance does the Bourns SRR1260A-100M offer for DC-DC converter filter stages?
The SRR1260A-100M provides a nominal inductance of 10 µH with an exceptionally low DC resistance (DCR) of 0.02 Ω. This ultra-low DCR minimizes I²R conduction losses in high-current buck or boost converter output filters, making it well-suited for efficient power conversion in battery-powered and industrial designs.
How does the 1212 SMD package size of the SRR1260A-100M affect component density on a power converter PCB?
The 1212 (4949) case size measures approximately 12 mm x 12 mm, which is a mid-size SMD power inductor footprint. This allows the SRR1260A-100M to handle higher saturation currents than smaller 0805 or 1008 inductors while still fitting on compact converter boards with 5 mm to 10 mm spacing between power components.
At what switching frequency range is the ferrite core SRR1260A-100M most effective in a buck converter design?
The SRR1260A-100M ferrite core inductor performs optimally in switching power supplies operating between 100 kHz and 1 MHz. At these frequencies, the 10 µH inductance provides adequate ripple current attenuation in a buck converter with a 5V to 12V input and a 1A to 5A output load, without excessive core loss from ferrite saturation.
