Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure proper thermal management, reduce electromagnetic interference (EMI), and optimize the component's performance.
To minimize electromagnetic interference (EMI), keep the inductor at least 5 mm away from sensitive components. You can also use shielding techniques, such as copper tape or mu-metal shielding, to contain the magnetic field.
Bourns recommends derating the voltage by 10-15% to ensure reliable operation. For the PWR163S-25-2501FE, the maximum allowable voltage is 225V (90% of 250V). Exceeding this voltage may reduce the inductor's lifespan or cause failure.
Use the inductor's datasheet specifications, such as the DC resistance (Rdc), inductance (L), and saturation current (Isat). Calculate the power rating using the formula: Power (W) = (Rdc x I^2) + (L x di/dt). The maximum current handling is typically 70-80% of the saturation current.
The SRF is typically not specified in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. The SRF can affect the circuit's impedance and resonance, potentially causing oscillations or instability. Ensure your circuit design takes into account the inductor's SRF to avoid unwanted resonances.
