NOTES:
1.It is recommended that a proper heat sink be used on the terminals of this device between the body and
soldering point to prevent damage from excess heat.
2.If operated over 10,000v/inch in length, devices should be immersed in oil or re - encapsulated.
EDI reserves the right to change these specifications at any time without notice.
