Reed Relay Datasheet HE3600 Miniature Single In-line Reed Relay Description The HE3600 is a miniature reed relay in a SIL package with a normally open contacts capable of switching up to 200Vdc at 10W. It is available with 5V, 12V, and 24V coils and has external magnetic shield and diode suppressed coil options. Features & Benefits Sub-miniature size and single Optional coil suppression in line configuration allows diode to protect coil drive very high packing densities, circuits minimizing space and cost Normally open contact Transfer molded package version gives maximum component RoHS Compliant protection External magnetic shield Lower power coil option consumption than competing Diode suppression option electromechanical devices Agency Approvals UL Recognized to UL 508 as Hermetically sealed switching an Industrial Control Switch contact is immune to the Agency Agency File Number effects of its environment E47258 Miniature single in-line package Note: Not all parts are UL Recognized.

Contact rating - Product of the switching voltage and current should never exceed the wattage rating. Contact Littelfuse for additional load/lofe 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 & 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.
