SCT013 Models

STC 013 000 Arduino Interfacing
STC-013-000 modules come without Sampling resistor, it provide current output proportionally to Input current. To convert current into voltage R5 (burden resistor) 18Ω to 33Ω must be added across CT terminal. - burden-resistor-dat - resistor-dat

STC 013 050 Arduino Interfacing
All the remaining module in STC-013 series comes with Inbuilt burden resistor. No need to add externally.
