CompareAutomotive Blade Fuses
8 specs
Automotive blade fuses protect 12V/24V/48V vehicle electrical circuits, standardized under ISO 8820-3 / SAE J1284 into six physical form factors (Micro2, Micro3, Mini, Low-Profile Mini, Regular ATO/ATC, and Maxi) using universal color-coded amperage ratings from 1A to 80A.
Automotive Relays & ISO Pinouts
9 specs
Automotive electromechanical relays switch high-current vehicle loads (cooling fans, fuel pumps, headlights, starter solenoids) using low-current control signals, standardized under ISO 7588 into Mini (1-inch cube) and Micro form factors with standard DIN 72552 terminal numbering (30, 85, 86, 87, 87a).
Car Battery BCI Group Sizes
8 specs
Lead-acid and AGM 12V starter batteries are standardized by the Battery Council International (BCI) and EN/DIN into group sizes defining physical box dimensions (length × width × height), terminal post orientation (top post vs side post vs recessed European DIN), hold-down ledge profiles, and Cold Cranking Amperage (CCA).
Spark Plug Threads & Dimensions
8 specs
Internal combustion engine spark plugs are standardized under ISO 1919 and SAE J548 into standard metric thread diameters (M10×1.0, M12×1.25, M14×1.25, M18×1.5), thread reaches (9.5mm to 26.5mm), hex wrench drive sizes (14mm, 16mm / 5/8", 21mm / 13/16"), and terminal configurations.
