Bourns recommends a symmetrical PCB layout with the inductor centered on the board, and the pads should be at least 1.5 mm from the board edge to minimize radiation. Additionally, a solid ground plane underneath the inductor can help reduce EMI.
The saturation current of the SRP6030VA-4R7M can be determined by applying a DC current to the inductor and measuring the inductance using an impedance analyzer or an LCR meter. The current at which the inductance drops to 10% of its nominal value is considered the saturation current.
The self-resonant frequency of the SRP6030VA-4R7M is not explicitly stated in the datasheet, but it can be estimated using the formula: SRF = 1 / (2 * π * sqrt(L * C)), where L is the inductance and C is the parasitic capacitance. For the SRP6030VA-4R7M, the estimated SRF is around 150 MHz.
The SRP6030VA-4R7M is rated for operation up to 125°C, but its performance may degrade at higher temperatures. Bourns recommends derating the inductor's current rating by 1.5% per degree Celsius above 125°C. Additionally, the inductor's insulation resistance may decrease at high temperatures, which can affect its reliability.
To minimize EMI and radiation, Bourns recommends using a shielded enclosure, keeping the inductor away from sensitive components, and using a common-mode choke or ferrite bead in series with the inductor. Additionally, the PCB layout should be designed to minimize radiation and ensure that the inductor is not placed near the board edge.
