Notes
Coil Data
Voltage: 12VDC.
Resistance: See Coil Data table.
Nom. Power: (@ 23°C coil temp. and rated coil voltage.):
1.6W, unsuppressed.
1.81W, with 680 ohm resistor.

load current.
(1) See Figure 1.
(2) Inrush current for lamp load.
(3) Allowable overdrive is rated at ambient temperature for 23°C or 85°C
as stated with no load current flowing through the relay contacts and
minimum coil resistance. Also see Figure 2 for maximum ambient
temperature versus applied coil voltage.
(4) See Figure 2.
(5) Current and times are compatible with circuit protection by a typical
automotive circuit breaker. Relay will make, carry and break the
specified current.

When relays are used in high splash areas, including most under-hood applications
the relay as well as the relay terminal to connector terminal interface should be
protected from direct spray. This can be achieved through the use of a Delphi
Packard Metri-Pack, 280 Series, Flexlock, Sealed Connector (typical Part Number
12110539) with corresponding terminals and cable seals. These parts are available
from Delphi Packard (1-800-PACKARD).
For passenger compartment or similar applications where weather sealing
of the relay and relay to terminal interface is not required.
