PolySwitch Resettable Devices – Strap Battery Devices
14
Tyco Electronics, pioneer of polymeric PTC resettable
devices, has developed several material platforms
specifically tailored to help protect battery applications.
Each of these material platforms offers different
performance characteristics, allowing the engineer
greater design flexibility. PolySwitch, Raychem Circuit
Protection Products, for battery protection includes
SRP, LTP, LR4, VTP, VLP, VLR and MXP series, disc, and
special application strap devices.
• Many material platforms and device form factors
give engineers more design flexibility
• Compatible with high-volume electronics assembly
• Assists in meeting regulatory requirements
• Low resistance devices increase battery operating
time
• RoHS compliant
• Lead free versions of all devices are available
• Broad range of resettable devices available
• Current ratings from 0.7A to 13A
• Voltage ratings from 6V to 30V
• Agency recognition, UL, CSA, TÜV
• Fast time-to-trip

PolySwitch Resettable Devices – Strap Battery Devices

Part Numbering System for Strap Battery Devices
Warning :
• Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame.
• The devices are intended for protection against 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 silicon 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.
• Operation in circuit with a large inductance can generate a circuit voltage (L di/dt) above the rated voltage of the PolySwitch resettable device.
Installation Guidelines for the Strap Family
• Polymeric PTC 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 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 Polymeric PTC device in tension will decrease the ability of the device to protect against electrical faults.
No residual force should remain on device after installation. Mechanical damage to Polymeric PTC chip may affect device performance and
should be avoided.
• Chemical contamination of Polymeric PTC 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.
• Polymeric PTC strap devices are designed 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 Polymeric PTC device to exhibit its specified performance, weld placement should be a
minimum of 2mm from the edge of the Polymeric PTC chip, weld splatter must not touch the Polymeric PTC chip, and welding conditions
must not heat the Polymeric PTC device above its maximum operating temperature.
• Polymeric PTC strap devices are not designed for applications where reflow onto flex circuits or rigid circuit boards is required.
• The polyester tape on PolySwitch strap devices is intended for marking and indentification purposes only, not for electrical insulation.
• The coating on MXP 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 devices have small Polymeric PTC chip size and therefore have weaker peel strength between polymer and Ni-foil of the chip.
Excessive mechanical force to the device may cause delamination of Ni-foil from polymer.
