Electrical parameters STHS237xA, STHS237xL

STHS237x

14/20

1.

Classification tested with exact resistor values. A 1% tolerance of classification resistor values is sufficient for compliance

with IEEE 802.3af classification current limits.

2.

Percentage of the intial steady state RTN inrush current value, below which inrush is terminated and PG goes active.

3.

Not tested in production.
