TF
thin film chip fuse
EU
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 right figure.
