1/ The dash number added to MS military standard number constitutes the MS PIN; for example MS14052-1.
2/ 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.
