1/ The coils are directly interchangeable with former PIN's (MS91189-29 thru -38). The decrease in maximum operating temperature from 125°C to 105°C does not downgrade these coils but assures satisfactory operation at 105°C for a minimum of 2,000 hours of life, rather than a shorter period of operation at 125°C.

Application notes:
1. The polarizing voltage during the moisture resistance tests is applied with the positive lead connected
To the coil terminals tied together, and the negative lead connected to the metal strap.
