New RoHS part numbers are shown.
Lead was removed from terminations. The last character is now L to indicate RoHS compliance.
(View old data sheet.)
|
- For use at 20 kHz and higher
- 1 to 100 Volt per Ampere sensitivity (variable by changing termination resistance)
- Incorporates current and sense windings in one small, encapsulated package
- 3750 Vrms winding to winding isolation
- RoHS-compliant. Tin-silver over copper terminations.
- Samples of all values plus sensor-only versions available in
