CURRENT WAVEFORM: Sinusoidal

LOAD: Resistive or Inductive

CONDUCTION ANGLE: 180°

The "K" package rating with its narrow leads is intended

for high surge condition use only and not recom-

mended for >50A rms continuous current use since lead

temperature depending on lead length can exceed PCB

solder melting temperature. "J" or "W" packages are

recommended for >50A rms continuous current require-

ments.
