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 voltage rating of 220V, it's essential to consider voltage stress during transient events. Bourns recommends limiting voltage stress to 250V to ensure long-term reliability.
The SRF can be calculated using the inductor's inductance and capacitance values. For the 2300HT-220-V-RC, the SRF is approximately 25 MHz. To minimize the impact of SRF on circuit performance, ensure the operating frequency is below the SRF or use a series resistor to dampen the resonance.
Store the inductor in a dry, cool place, away from direct sunlight and moisture. Handle the component by the body, avoiding touching the leads or core. Use anti-static wrist straps and mats to prevent electrostatic discharge damage.
