Absolute Maximum Ratings

Lead Temperature Soldering

Reflow (SMD styles only)...........60 sec. max above 183¡C, 230¡C peak

Frequency .......................................................................................5 to 400Hz

Over the extended ranges of temperature, voltage, and frequency not

covered by normal operating conditions, low frequency and run related

functions are allowed an additional 20% on specification limits. The

degradation shall not be permanent, and upon returning to normal

operating conditions shall be within the specification limits. Non-nor-

mal ÒRun ModeÓ operation is 45 hours cumulative life not exceeding a

continuous run time of 10 minutes with a 10 minute ÒOffÓ time follow-

ing each successive operating cycle.
