ORDERING INFORMATION
Low profile: 15.7mm height
1a/1c 16 A power relay LZ RELAYS
FEATURES
1. Low profile type with height of
15.7 mm
Slim, low profile type with dimensions of
28.8 (L) 12.5 (W) 15.7 (H) mm
1.134 (L) .492 (W) .618 (H) inch.
2. High insulation resistance
Superior insulation characteristics have
been achieved by maintaining an
insulation distance between coil and
contacts of at least 10 mm for both
creepage distance and clearances.
Furthermore, anti-surge voltage is 10 kV
and higher. (Supports European
reinforced insulation requirement.)
3. Superior heat resistance
Can be used in ambient temperatures up
to 85C 185F for the class B and 105C
221F for the class F.
4. Low operating power
Power saved with a nominal operating
power of only 400 mW.
5. Conforms to the various safety
standards:
UL, C-UL, VDE approved.
6. Superior heat resistance and
tracking resistance
EN60335-1 GWT compliant (Tested by
VDE) type available.
TYPICAL APPLICATIONS

Electrical life (Sealed type)
In order to obtain the full rated life cycles,
the relay should be properly vented by
removing the vent nib after the soldering/
washing process.
