Axial Lead Reed Switches

High Power > DRR-DTH

DRR-DTH 39.7mm Standard Changeover Reed Switch

RoHS

Description

The DRR-DTH Reed Switch is a large changeover switch with a 39.67mm long x

5.33mm diameter (1.562” x 0.210”) glass envelope, capable high voltage and

power switching up to 500Vdc at 30W. The DRR-DTH has an insulation

resistance of 10

ohms minimum and contact resistance of less than

125 milli-ohms.

The DRT-DTH Reed Swith, another varient of the DRR-DTH, is made for

heavier loads.

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.
