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 note that the inductor can withstand a maximum voltage of 50 V. Exceeding this voltage may cause damage or reduce the inductor's lifespan.
The SRF can be calculated using the inductor's inductance (L) and capacitance (C) values. The formula is: SRF = 1 / (2 * π * sqrt(L * C)). You can find the necessary values in the datasheet or by contacting Bourns' technical support.
The operating temperature range for the 3310P-025-103L is -40°C to +125°C. However, it's essential to note that the inductor's performance may degrade at extreme temperatures, and derating may be necessary.
