MRPR-8 20.3mm Miniature High Voltage Reed Switch
RoHS
Description
The MRPR-8 Reed Switch is a miniature, normally open switch with a 20.32mm
long x 2.84mm diameter (0.800” x 0.112”) glass envelope, capable of high
voltage and power switching of 265Vac at 50VA. The MRPR-8 has high
insulation resistance of 10¹⁰ ohms minimum and contact resistance less than
100 milli-ohms.
Features
• Miniature normally open switch
• Capable of switching 265Vac or
1.0A at up to 50W/VA
• Minimum voltage breakdown
750Vdc
• Available sensitivity range

Notes:
1. Contact rating - Product of the switching voltage and current should never exceed the wattage rating. Contact Littelfuse for additional load/life information.
2. When switching inductive and/or capacitive loads, the effects of transient voltages and/or currents should be considered. Refer to Application Notes AN108A and AN107 for details.
3. Electrical Load Life Expectancy - Contact Littelfuse with voltage, current values along with type of load.
4. Breakdown Voltage - per MIL-STD-202, Method 301.
5. Storage Temperature - Long time exposure at elevated temperature may degrade solderability of the leads.
