1 / 3 page littelfuse.com © 2017 Littelfuse Revised: 07/18/17 Specifications are subject to change without notice. MVSR-20 19.7mm Reed Switch Description The MVSR-20 reed switch is a miniature, normally open switch with a 19.69mm long x 2.66mm diameter (0.775” x 0.105”) glass envelope, capable of high voltage switching of up to 1kVdc at 1mA. It has high insulation resistance of 10¹² ohms minimum and contact resistance less than 100 milli-ohms.

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. Note: Contact Littelfuse for specific agency approval ratings. |
