Reed Relay
Datasheet
H3300
Miniture Single In-line Reed Relay
Description
The HE3300 is a miniature reed relay in a SIL package with a
choice of normally open, normally open high voltage or changeover
contacts capable of switching up to 300Vdc at 10W. It is available
with 5V, 12V, and 24V coils and has external magnetic
shield options.

Notes:
1.
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.
