Q: TPA2018 package


TPA2018 is packed by Nano-Free™ WCSP(YZF), which soldering ball is about φ0.3mm.
When I use TPA2018 as 4ohm speaker amplifier at 5V, the maximum current may be 1.25A on the soldering ball. My concern is that soldering ball is broken by over-current, so I like to know the maximum current specification of WCSP soldering ball.

Hi,

Up to 2A is acceptable as long as the junction temperature stays below 125C, so you should be fine in your case.
