104-1-A-12/4D,Reed Relay, SPST-NO, 12 VDC, 104 Series, Through Hole, 500 ohm, 1 A

104-1-A-12/4D is a 104 series high voltage dry reed relay. This relay is ideal for applications such as transformer or cable testing and any other automatic test equipment where high voltages are involved. When mains voltages are switched, they used to control and isolate SCR or triac gates. It has an internal mu-metal screen to eliminate problems that would be experienced due to magnetic interaction when they are closely stacked.- Upto 4KV stand-off, stacking on 6.35mm pitch- Small size, shock resistance 50g, internal diode is present- One or two switches in a single package- 1 Form A, switch number 4 (4KV)- Coil voltage is 12V, coil resistance is 500 ohm- Maximum operating voltage at 25°C is 9V- Minimum operating voltage at 25°C is 1.2V- Power rating is 25W, maximum switch current is 1A- Maximum switching volts is 1000VDC, operating temperature range is -20°C to +85°C- Minimum stand-off voltage is 4000V, life expectancy is 10⁸
