Installation Guidelines

•

Due to the fact that PPTC devices operate by thermal expansion of the conductive polymer, it is

imperative that designs allow enough space over the life of the product to accommodate the expansion. If

the device is used in designs that do not account for the expansion or if the device is placed under

pressure, the device cannot be relied on to properly protect against damage caused by fault conditions.

•

Bending, twisting, or leaving the PPTC device in tensile conditions will lessen the PPTC device’s ability

to protect against damage caused by electrical faults. The PPTC device should experience no force after

installation. Any mechanical damage to the PPTC device can affect the performance and should therefore

be avoided.

•

Avoid contact of PPTC device with chemical solvent, including some inert material such as silicone

based oil, lubricant, grease, cleaning agents, and etc. Prolonged contact will damage the device

performance.

•

Strap type PPTC devices are designed to be welded to battery cells or to pack interconnect straps.

Weld placements should be a minimum of 2mm from the edge of the PPTC device, and no weld splatter

should come in contact with the PPTC device. In addition, welding temperatures should not exceed the

maximum operation temperature of the PPTC device.

•

Strap type PPTC devices are not designed for reflow installation like flex circuits or rigid circuit boards.

•

The tape used on strap type PPTC devices is not designed as an electrical insulator, its use is merely

for identification and marking.
