LED & lighting

Quick documentation & first test preparation

  1. Identify component CH455G and its package.
  2. Check operating current, polarity and forward or driver voltage.
  3. Size the current limiting and thermal dissipation.
  4. Consult the application circuit in the linked documentation before testing.

CH455G
