Battery Mini-Breakers (Thermal Cutoff Devices)

Metal Hybrid PPTC > MHP Series

RoHS

MHP-TAT18 Series Breaker

Description

The new Metal Hybrid PPTC device, MHP-TAT18, offers a

9VDC rating and a higher current rating than typical MHP-

TAM devices. MHP-TAT18 helps to meet the battery safety

requirements of higher-capacity Lithium (Ion) Polymer and

prismatic batteries found in most mobile devices such as

laptop PC’s, tablets, and smart phones. MHP technology

connects a bimetal protector in parallel with a Polymeric

PositiveTemperature Coefﬁcient (PPTC) device. The PPTC

device to act as a heater and to help keep the bimetal

latched until the fault is removed. The resulting MHP-

TAT18 series helps to provide resettable overtemperature

protection.

Precautions for Electrical Characteristics:

a. Device electrical characteristics may change depending on installation conditions. Users should independently evaluate the suitability of and test each product in their own application.

b. If any terminal or lead extensions are added to the device, especially in the case of high current discharging, the device performance may be negatively impacted due to variations

in welding methods or materials. Please avoid designs that might cause heat to be generated around the joints of the lead extensions or on the extended terminals.

c. SMT solder reﬂow, wave-soldering and manual soldering irons are not permitted.

Speciﬁcations are subject to change without notice.
