features
•Small, lightweight design
•Special manufacturing method stabilizing fusing
characteristics and occupying less area
•Low power consumption and less voltage drop
due to low internal resistance
•Suitable for overcurrent protection of circuit block
in electronic devices
•Suitable for flow and reflow soldering
•Marking: Black body color with white marking:
TF10BN, TF10SN; white marking: TF10AT
•Products with lead-free terminations meet EU RoHS
and China RoHS requirements

Stationary Current: Regard the peak of stationary current
waveform as stationary current value when the stationary
current is repeated pulse.
Temperature Derating: Rated current needs to be
derated if used at an ambient temperature 70℃or above.
Refer to the derating coefficient on the left figure.
