MDSR-10 10.2mm Sub-miniature Reed Switch

RoHS

Description

The MDSR-10 Reed Switch is a sub-miniature, normally open switch with a

10.16mm long x 1.80mm diameter (0.400” x 0.071”) glass envelope, capable of

switching 200Vdc at 10W. It has high insulation resistance of 10¹² ohms

minimum and low contact resistance of less than 120 milli-ohms. This reed

switch is also available in a surface mount version, that is, MDSM-10.

Features

• Sub-miniature normally

• 10¹²Ohms insulation resistance

• Available sensitivity range

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.
