SMART COIL IGN-1A

Looking for a high powered ignition system? These coils are designed to put out 103 mJ per spark, with a longer spark duration (2.9 ms) than what you’d see with a capacitive discharge. A 19 amp IGBT ignitor is built in. They can be driven with a 5 volt logic level output –  Maximum recommended duty cycle is 40%. The connector and pins are included! Here is the connector pinout: A – Ignition signal from ECU B – Logic ground, connect to ECU ground C – Spark wire ground, connect to cylinder head D – Power ground, connect to battery negative E – 12 volt power The coil dwell starts when a 5 volt signal is applied to pin A, and the coil fires when the voltage drops to zero. The signal is similar to an LSx coil, although it does need a bit more current to trigger than the LSx coils. Coil specs: Minimum voltage output (no load, at recommended dwell): 40,000 volts Output energy: 103 mJ Spark duration: 2.9 ms Primary resistance: 0.5 ohms (not directly measurable) Primary inductance: 4.8 mH (not
