STE Capacitors and Protection Components in Published Teardowns

Original report

STE edition

Adapted from Chongdiantou

Chongdiantou groups reported STE component use across chargers, adapters, power strips and portable power stations.

Chongdiantou's July 2024 roundup groups reported STE component use across chargers, adapters, power strips and portable power equipment. The inventory below preserves its component-family coverage. These are reported examples, not brand endorsements or evidence of current use in every production revision.

C denotes USB-C and A denotes USB-A. Names without a confirmed English market equivalent use romanized source labels. Repeats across families preserve different component categories.

X2 safety capacitors

The source lists 275, 305, 310, 330 and 350 VAC options for across-line suppression and some capacitive-dropper applications. These historical descriptions require confirmation against the exact variant and current specification.
