Plug-in Micro ISO Relays
1) The values apply to a resistive or inductive load with suitable spark suppression and at
maximum 13.5VDC for 12VDC or 27VDC for 24VDC load voltages.
2) For a load current duration of maximum 3s for a make/break ratio of 1:10.
3) Current and time are compatible with circuit protection by a typical automotive fuse.
Relay will make, carry and break the specified current.
4) See chapter Diagnostics of Relays in our Application Notes or consult the internet at
http://relays.te.com/appnotes/
5) Electrical endurance data is not valid for diode versions. Any diode or pn-junction
parallel to the coil (internal or external) will significantly decrease the electrical lifetime,
especially when used for inductive loads.
6) Not applicable for polarity reverse loads like power windows
■ High current version with limiting continuous current 30A at 85°C
■ Pin assignment according to ISO 7588 part 3
■ Customized versions on request
– 24VDC versions with special contact gap
– Integrated components (e.g. diode)
– Customized marking
– Special covers (e.g. notches, release features)
– For latching version refer to Micro Relay Latching
– For low noise version refer to Micro Relay Low Noise
– For high current version refer to part number table
Typical applications
Cross carline up to 30A for example: ABS control, blower fans, cooling fan,
door control, door lock, fuel pump, heated front screen, immobilizer, interior
lights, seat control, seatbelt pretensioner, sun roof, trunk lock, valves,
window lifter, wiper control.
Max. DC load breaking capacity
Load limit curve 1: arc extinguishes during transit time (CO contact).
Load limit curve 2: safe shutdown, no stationary arc (NO contact).
Load limit curves measured with low inductive resistors verified for 1000 switching events.
