SMD4532-400NF

RUILON Shenzhen Ruilongyuan Elec · Gas Discharge Tube Arresters (GDT) · 1812

SMD4532-400NF from RUILON Shenzhen Ruilongyuan Elec, in a 1812. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1 passive Terminal 1 of the two-electrode GDT (non-polarized, interchangeable with terminal 2), with 400V ±30% DC spark-over voltage at 100V/s and 2kA 8/20μs impulse discharge current rating.
2 2 passive Terminal 2 of the two-electrode GDT (non-polarized, interchangeable with terminal 1), with less than 0.5pF capacitance at 1MHz and 1GΩ minimum insulation resistance.
