Axial Lead Reed Switches

Low Power > MRPR-3

MRPR-3 19.7mm Miniature Reed Switch

OBSOLETE:

Date: April 28, 2016

RoHS

Replacement Series: MRPR-20 Series

PCN#: (Sorry i can;t recall this already)

Description

The MRPR-3 Reed Switch is a miniature, normally open switch with a 19.69mm

long x 2.84mm diameter (0.770” x .112”) glass envelope, capable of switching up

to 200Vdc at 50W. The MRPR-3 has high insulation resistance of 10¹⁰ohms

minimum and contact resistance less than 100 milli-ohms.

Features

• Miniature normally open switch

• Switch contacts capable of

switching 200Vdc or 1.5A at

up to 50W.

• Available sensitivity range

22-43 AT

Agency Approvals

Benefits

• Hermetically sealed switch

contacts are not affected by and

have no effect on their external

environment

• Zero operating power required

for contact

• Power switching with a

miniature switch

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
