Metal Hybrid PPTC > MHP Series

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 device. This helps to meet the battery safety

requirements of higher-capacity LiP and prismatic

batteries found in the latest gaming PC and ultra-book

products. Hybrid MHP technology connects a bimetal

protector in parallel with a Polymeric Positive Temperature

Coefficient (PPTC) device. The resulting MHP-TAT18

(Thermal Activation) series helps to provide resettable

overtemperature protection, while utilizing the PPTC device

to act as a heater and to help keep the bimetal latched until

the fault is removed.

Precautions for Electrical Characteristics:

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

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.

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

Specifications are subject to change without notice.

The current versus temperature curve was derived from placing test samples in an oven at

25°C, 40°C, 60°C, 70°C, and 75°C, increasing current flow through the sample at a rate of

0.1A/minute and recording the current value when the sample trips.

Temperature (ºC)

Precautions for Rating

The power supply voltage must be less than the rated

voltage of the device. Operation above the voltage rating

may result in device damage, smoke or flame.

Designs must be selected in such a manner that the

device hold current is higher than the normal current value

in the circuit and that the device trip current is lower than

the abnormal current value. Selecting device hold current

and trip current values that are too low for the application

may interrupt the circuit under normal usage conditions.

This product should not be used in an application where

the maximum interrupt current can be exceeded in a short

circuit condition.

The devices are intended for protection against damage

caused by occasional over current or over temperature fault

conditions and should not be used when repeated fault

conditions or prolonged trip events are anticipated.

The devices may not perform as specified if mechanical

pressure is added while the device is in the tripped state or

exposed to temperature conditions over 100°C.

Specifications are subject to change without notice.

Handling Precautions

The device is composed of plastic parts, please do not

clamp or dent the housing with a tool as this might cause a

resistance increase and product damage.

When welding product terminals or mounting the breaker

on battery (cell), please be careful not to apply excessive

bending, twisting or force on the product and terminals.

The excessive stress might cause a resistance increase or

product damage.

Please refer to following cautions.

• Do not apply more than 10N bend force to product.

(Fig. 1)

• Do not apply more than 1.5cN*m twist torque to the

product. (Fig. 2)

• Do not apply more than 20N deflection force to product.

(Fig. 3)

• Do not apply more than 2N force to the terminals.

(Fig. 4)

• Do not apply more than 0.6cN*m twisting torque to the

terminals. (Fig. 5)

• Do not bend the terminals more than 45°at the end.

(Fig. 6)

• Should not twist terminals more than 20°C with breaker

body fixed.

Product terminals can be welded using direct welding

and series welding methods. In either case, please use a

suitable Jig so that the device will not be subjected to the

stress conditions listed above.

Pull strength and detach strength of the terminal welds

are per user requirements. However, if the welding is

controlled by resistance, the measurement should be made

as close as possible to the weld point by a “4-point clip

method” using milliohm meter to ensure accuracy.

Please avoid putting the stress on the device, as listed

above, when a jig, fitting or additional welding process is

used. Please re-confirm the resistance value whenever a

new process is added.

The device is intended to be used for applications which

are common for general electronic devices. Usage in

any of the special environments or conditions as listed

below may adversely impact the device performance and

therefore users should carefully consider conditions of use

of the end product and the potential impact on reliability or

performance when incorporating this device into any design

to carefully examine the actual performance and reliability of

the device.

• Environment where the devices are exposed to water,

oil, chemical solutions, and/or organic solvents.

• Installation in an area close to a heat source or adjacent

to or near flammable objects such as plastic wires.

• Environment in which the device is constrained by

Application Environment

pressure, sealing or resin coating.

• Environment where water condenses on the device.

• Environment with salt air or with corrosive gas such as

, H

S, NH

, SO

, and NOX.

• Environment with grit and dust and/or under direct

sunlight.

• Environment outside of recommended operating

temperature.
