FEATURES

 

• Breakdown voltage between contacts and coil: 2,000 V

• Surge withstand between contacts and coil: 2,500 V

• High contact capacity: 2 A 30 V DC

• Surface-mount type available

 

SPECIFICATIONS

Notes:

 

f

 

1This value can change due to the switching frequency, environmental conditions, 

and desired reliability level, therefore it is recommended to check this with the ac-

tual load.

 

f

 

2The upper limit for the ambient temperature is the maximum temperature that 

can satisfy the coil temperature rise. Under the packing condition, allowable tem-

perature range is from –40 to +70°C 

–40°C to +158°F

.
