1206TD-25AS
Time Delay | 0.126x0.064 inch
Thick Film Chip Fuses
1206TD Series are the fuses set the industry standard for performance, reliability and quality. The solder-free design provides excellent on-off and temperature cycling characteristics during use and also makes our SMD fuses more heat and shock tolerant than typical subminiature fuses.

- 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
