Installation Guidelines for the Strap Family

• PPTC devices operate by thermal expansion of the conductive polymer. If devices are placed under pressure or installed in spaces that would

prevent thermal expansion, they may not properly protect against damage caused by fault conditions. Designs must be selected in such a

manner that adequate space is maintained over the life of the product.

• Twisting, bending, or placing the PPTC device in tension will decrease the ability of the device to protect against damage caused by electrical

faults. No residual force should remain on device after installation. Mechanical damage to the PPTC device may affect device performance and

should be avoided.

• Chemical contamination of PPTC devices should be avoided. Certain greases, solvents, hydraulic fluids, fuels, industrial cleaning agents, volatile

components of adhesives, silicones, and electrolytes can have an adverse effect on device performance.

• PPTC strap devices are intended to be resistance welded to battery cells or to pack interconnect straps, yet some precautions must be taken

when doing so. In order for the PPTC device to exhibit its specified performance, weld placement should be a minimum of 2mm from the edge

of the PPTC device, weld splatter must not touch the PPTC device, and welding conditions must not heat the PPTC device above its maximum

operating temperature.

• PPTC strap devices are not intended for applications where reflow onto flex circuits or rigid circuit boards is required.

• The polyester tape on PPTC strap devices is intended for marking and identification purposes only, not for electrical insulation.

• The coating on MXP and MGP devices is intended to prevent oxidization/aging of the devices. Damaging the coating or causing the coating to

delaminate can have negative effects on device performance and should be avoided.

• MXP and MGP devices have a small PPTC chip size and therefore have weaker peel strength between the polymer and Ni-foil of the chip.

Excessive mechanical force to the device may cause delamination of Ni-foil from the polymer.
