1206 Thin Film Surface Mount Fast Blow Chip Fuse 12B1100B 1A 125V
3216 Metric With 50 Amp Interrupting Rating
Description
Range of chip fuses are compact and precise circuit protection for
all applications
Broad range of surface mount chip fuses to provide optimal
overcurrent protection in dense secondary circuits. These circuits
are found in consumer electronics, such as battery operated,
handheld, and portable electronic devices including laptops, cell
phones, GPS systems, PDAs and many other devices which continue to
demand increasingly smaller componentsThe range of fuses is offered
with quick, super-quick-acting, and time-lag characteristics. Each
fuse series boasts unique performance characteristics such as low
voltage drop and high breaking capacity. The current ratings range
from 50 mA to 25 A. Rated voltage for these components are up to
125 VAC/VDC.
