SLD-Axial Leaded Strap Lead(Pb) Free PTC Devices
SLD-Axial Leaded Strap Lead(Pb) Free PTC Devices
Description
The new SLD Axial Leaded Strap Lead(Pb) Free PTC device are designed
based on a proprietary conductive polymer material, to provide both
overcurrent and overtemperature protection for rechargeable battery cells.
The SLD Axial Leaded Strap Lead(Pb) Free devices featuring a slim, low
profile and low resistance design and are ideal to install directly on the latest
generations of battery cells for longer battery run time.
SLD products provide reliable, noncycling protection against overcharging
and short circuits events and increase the battery safety level.

SLD-Axial Leaded Strap Lead(Pb) Free PTC Devices
How to Select a Polymer PTC fuse
(1) Determine the following operating parameters for the circuits:
(A) Normal Operating Current (I hold)
(B) Maximum Circuit Voltage (V max)
I Maximum Interrupt Current (I max)
(D) Normal Operating Temperature (min ºC /max ºC)
(2) Select the device form factor and dimension suitable for the application:
Axial Leaded Strap Device (SLD, VTD, LTD, LRD , STD ,LTD Series)
Surface Mount Device (SMD Series)
Radial Leaded Device (RLD Series)
Other Custom-designed Device (Disc/Chip)
(3) Compare the maximum ratings for V max and I max of the PTC device with the circuit in
application and make sure that the circuit’s requirement does not exceed the device ratings.
(4) Check that the PTC device’s trip time (time-to-trip) will protect the circuit.
(5) Verify that the circuit operating temperatures are within the PTC device’s normal operating temperature range.
(6) Verify the performance and suitability of the chosen PTC device in the application.
