Vishay Dale
Through Hole Transformers Trigger, SCR Isolation
FEATURES
• Designed for low-cost trigger source isolation in
SCR power control circuits
• Small physical size and low profile provide
packaging advantages
• Designed to transfer high amplitude or long duration
pulses without saturation
• Industrial and commercial applications include motor
speed controls, lighting controls and heater controls
• Interchangeable. Designed for circuit board mounting
using same mounting dimensions as 11Z and PT-20
models
• Material categorization: for definitions of compliance
