MITI-3V1 7mm Ultra-Miniature Reed Switch
RoHS
Description
The MITI-3V1 ultra-miniature reed switch is a normally open switch with a
7.00mm long x 1.80mm diameter (0.276” x 0.071”) glass envelope, which is
capable of switching 170Vdc at 10W. It has a high insulation resistance of 10¹²
ohms minimum and low contact resistance of less than 150 milliohms.
The MITI-3V1 is also available in a surface mount version, that is, MISM-3V1.
Features
• Ultra-miniature, normally
open switch
• Capable of switching 170Vdc or
0.25A at up to 10W
• Available sensitivity range 6-10 AT

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.
