6. Frequently Asked Questions
▶>
It's commonly used in SMPS, LED lighting drivers, high-voltage converters, and PFC circuits.
>
Technically yes, but it’s more optimized for sensing and surveillance rather than consumer-grade remotes which typically use 940nm but lower output power.
>
Ensure adequate gate driving strength, low parasitic inductance, and sufficient cooling.
>
Use a smartphone camera or IR sensor module to verify IR emission during operation.
>
Most IR5C940AC-X4 variants are RoHS-compliant, but it should be verified with the supplier for each batch.
