MRPR-20 20.3mm Miniature High Voltage and High Power Reed Switch

RoHS

Description

The MRPR-20 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-20 has high

insulation resistance of 10¹⁰ohms minimum and contact resistance less than

100 milli-ohms.

Features

• Miniature normally open switch

• Capable of switching 265Vac or

1.5A at up to 50W/VA

• Available sensitivity range

17-43 AT

• Minimum breakdown voltage

750Vdc

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.
