Dielectric test voltage 2,500 volts rms, max. 50-60Hz
1 . Corrosion resistant terminals designed for .250 female quick connector, wrap around or solder. 2. A thin film of silicone thermal compound is recommended between the Minibridge R case and mounting surface for improved thermal conduction. 3. Higher dielectric strengths available. Consult factory.
NOTES: Maxinum lead and terminal temperature for soldering, 3/8 inch from case,5 seconds at 250 OC EDI reserves the right to change these specifications at any time without notice.
