Bourns

Polymeric Thermal Cutoff Devices (P-TCO)
Application Notice
Users are responsible for independent and adequate evaluation of Bourns
®
Polymeric Thermal Cutoff (P-TCO) devices in the user’s
application, including the P-TCO device characteristics stated in the applicable data sheet.
Polymeric Thermal Cutoff devices must not be allowed to operate beyond their stated maximum ratings. Inadequate adherence
to such maximum ratings could result in damage to the P-TCO device and lead to electrical arcing and/or fire. Circuits with
inductance may generate a voltage above the rated voltage of the P-TCO devices and should be thoroughly evaluated within the
user’s application during the P-TCO selection and qualification process.
Polymeric Thermal Cutoff devices are intended to protect against adverse effects of temporary overtemperature conditions and
are not intended to serve as protective devices where such conditions are expected to be repetitive or prolonged.
As a normal function of operation, Polymeric Thermal Cutoff devices experience thermal expansion under fault conditions.
Thus, a P-TCO device must be protected against mechanical stress, and must be given adequate clearance within the user’s
application to accommodate such thermal expansion. Rigid potting materials or fixed housings or coverings that do not provide
adequate clearance should be thoroughly examined and tested by the user, and may result in the malfunction of P-TCO devices
if the thermal expansion is inhibited.
Exposure to lubricants, silicon-based oils, solvents, gels, electrolytes, acids, and other related or similar materials may adversely
affect the performance of Polymeric Thermal Cutoff devices.
Aggressive solvents may adversely affect the performance of Polymeric Thermal Cutoff devices. Conformal coating,
encapsulating, potting, molding, and sealing materials may contain aggressive solvents including but not limited to xylene and
toluene, which are known to cause adverse effects on the performance of P-TCO devices. Such aggressive solvents must be
thoroughly cured or baked to ensure complete removal from P-TCO devices to minimize the possible adverse effect on the
device.
Recommended storage conditions should be followed at all times. Such conditions can be found on the applicable data sheet
and on the Polymeric Thermal Cutoff Device Moisture/Reflow Sensitivity Classification (MSL) note:
