Bourns recommends a symmetrical layout with a central pad for the inductor, and a minimum of 2 oz copper thickness for optimal thermal performance. A recommended land pattern is available in the Bourns application note AN-13.
While the datasheet only specifies up to 1 MHz, the 3299W-1-500LF can be used in higher frequency applications. However, core losses and skin effect will increase, reducing inductance and increasing resistance. Consult Bourns' high-frequency modeling tools or contact their application engineers for guidance.
The maximum allowed voltage is not explicitly stated in the datasheet. However, as a general guideline, Bourns recommends limiting the voltage across the inductor to 2-3 times the rated current multiplied by the DCR (DC Resistance) to avoid saturation and ensure reliable operation.
The 3299W-1-500LF is rated for operation up to 125°C. However, derating may be necessary for temperatures above 105°C. Consult the Bourns temperature derating chart or contact their application engineers for guidance on high-temperature applications.
Bourns recommends storing the 3299W-1-500LF in a dry, cool place, away from direct sunlight and moisture. Avoid bending, flexing, or twisting the leads, and handle the components by the body, not the leads, to prevent damage.
