NOTES:
1. Corrosion-Resistant Terminals Designed for .250" Female Quick Connect Wrap Around
or Solder.
2. A Thin Film of Silicone Thermal Compound is Recommended Between Bridge and
Mounting Surface for Improved Thermal Conduction.
3. These FCI Bridges Are Also Available in Fast Recovery, In Positive and Negative Center
Tap and in Double Configurations. Consult with FCI for Your Special Requirements.
