2000W (suitable for high-load resistive devices).
According to standard reference data for MY-9892-based modules (such as those engineered around BTA16-600B or BTA25 Triacs ), the circuit operates within strict boundaries: Rated Value Technical Notes 110V – 230V AC
The schematic of the MY-9892 contains an RC snubber network (resistor and capacitor combined) built to suppress steep voltage spikes (
The circuit includes anti-peak and over-voltage protection, often utilizing an RC absorption circuit (EOC) to handle inductive spikes. Application Guide my 9892 datasheet
The IRISO datasheet for this series is essential for PCB layout. It details the precise footprint dimensions and the recommended soldering profile for reliable assembly. For example, the connector's rated withstand voltage of 250V AC is a critical parameter for ensuring electrical safety margins in a design.
The series from IRISO refers to a family of board-to-board connectors with a floating design, used for establishing reliable connections between PCBs.
