- DC Interrupting Rating (Measured at rated voltage, time constant of less than 50 microseconds, battery source)
- DC Cold Resistance are measured at <10% of rated current in ambient temperature of 25℃
- Typical Pre-arcing I2 t are measured at 10In Current Choice fuse for surge application (USB charger etc.), make sure the I2 t of fuse is 4 times than surge.
- Specifications are subject to change without notice. Application testing is strongly recommended.
