POLYSWITCH RESETTABLE

DEVICES

Strap Battery Devices

Littelfuse PolySwitch, a pioneer of polymeric positive

temperature coefficient (PPTC) resettable devices, offers

several material platforms to help protect battery

applications. Each of these material platforms offers

different performance characteristics that allow the

engineer greater design flexibility. PolySwitch devices

for battery protection include SRP, LR4, VTP, VLP,

VLR, MXP and MGP series, disc and special application

strap devices.

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.

Warning :

• Users should independently evaluate the suitability of and test each product selected for their own application.

• Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and ﬂame.

• These devices are intended for protection against damage caused by occasional overcurrent or overtemperature fault conditions and should

not be used when repeated fault conditions or prolonged trip events are anticipated.

• Contamination of the PPTC material with certain silicone-based oils or some aggressive solvents can adversely impact the performance of the devices.

• Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and

mechanical procedures for electronic components.

• PPTC devices are not recommended for installation in applications where the device is constrained such that its PTC properties are inhibited,

for example in rigid potting materials or in rigid housings, which lack adequate clearance to accommodate device expansion.

• Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above the rated voltage of the device.

Notice:

Information furnished is believed to be accurate and reliable. However, users should independently evaluate the suitability of and test each product selected for their own

applications. Littelfuse products are not designed for, and shall not be used for, any purpose (including, without limitation, military, aerospace, medical, life-saving, life-

sustaining or nuclear facility applications, devices intended for surgical implant into the body, or any other application in which the failure or lack of desired operation of the

product may result in personal injury, death, or property damage) other than those expressly set forth in applicable Littelfuse product documentation. Warranties granted by
