Although the datasheet specifies a storage temperature range of -40°C to 150°C, the recommended operating temperature range for reliable operation is typically between -25°C to 85°C, depending on the application and environmental conditions.
While the CD123D-B120R is suitable for high-frequency applications, its self-resonant frequency (SRF) should be considered. The SRF is around 100 MHz, so it's recommended to keep switching frequencies below 50 MHz to minimize potential losses and ensure efficient operation.
For optimal performance, it's recommended to follow a symmetrical PCB pad layout, with the pad size matching the inductor's footprints. This helps to minimize inductance variation and ensures reliable soldering. A minimum of 1.5 mm clearance around the inductor is also recommended to prevent electromagnetic interference.
When selecting an inductor, consider factors such as inductance value, current rating, operating frequency, and DC resistance. Also, evaluate the inductor's physical size, temperature range, and package type to ensure it meets your application's requirements. Consult Bourns' selection guides and datasheets or contact their technical support for assistance.
The CD123D-B120R is commonly used in DC-DC converters, power supplies, EMI filter circuits, and audio equipment. Its high inductance value and low DC resistance make it suitable for applications requiring high energy storage and low power losses.
