Bourns provides a recommended PCB layout and land pattern in their application note AN204, which can be found on their website. It's essential to follow these guidelines to ensure optimal performance, low inductance, and minimal parasitic effects.
The self-resonance frequency (SRF) of the chip inductor can affect its performance by causing impedance peaks and altering the inductor's behavior. It's essential to consider the SRF when designing the circuit, especially in high-frequency applications. Bourns provides SRF data in their datasheet, and engineers should ensure the operating frequency is below the SRF to maintain optimal performance.
The maximum allowable voltage across the inductor is not explicitly stated in the datasheet, but it's typically limited by the insulation resistance and dielectric strength of the material. Engineers should consult Bourns' application notes or contact their support team to determine the maximum allowable voltage for their specific application. Exceeding the recommended voltage can lead to reduced reliability, increased leakage current, and potentially even failure.
The operating temperature range can affect the inductor's performance by altering its inductance value, Q factor, and resistance. The CW252016-R68J is rated for operation from -40°C to +125°C, but engineers should be aware that extreme temperatures can lead to reduced performance, increased power losses, and potentially even failure. It's essential to consider the operating temperature range when designing the circuit and selecting components.
Bourns recommends storing the CW252016-R68J in a dry, cool place, away from direct sunlight and moisture. Engineers should handle the components by the body, avoiding touching the leads or component surfaces to prevent damage from electrostatic discharge (ESD). It's also essential to follow proper soldering and assembly procedures to prevent thermal shock and mechanical stress.
