Maximum ratings specified with rated secondary terminating resistance and 1 turn primary.
Amp-µSec rating of primary equals to volt µSec rating of secondary when secondary is terminated in rated resistance.
Maximum operating temperature 105°C.
For non-RoHS parts, replace PT prefix with 42- (e.g. PT27210 becomes 42-27210).
Terminal finish is compliant to RoHS requirements
