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, minimize parasitic inductance, and optimize 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.
While the datasheet specifies a maximum rated current, it's essential to consider the voltage across the inductor as well. The maximum allowable voltage is typically 2-3 times the rated voltage. Exceeding this can lead to premature failure or reduced lifespan.
The SRF can affect the inductor's performance and potentially cause oscillations. To mitigate this, use a series resistor or a damping network to reduce the Q factor and minimize the impact of SRF on your design.
The 3313J-2-102E has a maximum operating temperature of 125°C. Ensure good airflow, use a heat sink if necessary, and avoid exceeding the maximum rated current to prevent overheating and ensure reliable operation.
