Description
1. Description
1.1 General Description
The BM43THA80C is a CMOS compatible thermopile temperature sensor based on MEMS (microelectromechanical systems) technology. This thermopile detector consists of thermopile MEMS chip, 514um infrared band pass filter, a NTC thermistor for temperature compensation and a small size TO
Package.
1.2 Features
Non-contact surface temperature measuring
TO housing with an 5-14um infrared filter
Using NTC thermistor for ambient temperature compensation
High sensitivity
Fast response time
Wide working temperature: -40℃+120℃(Temperature range can be extended to +1000℃by
using specific infrared lens)
1.3 Applications
Non-contact human body temperature infrared thermometer
Microwave oven
Automatic induction equipment
Heating, Ventilation and Air Conditioning(HVAC)
Appliance

●General Precaution
1) Before you use our Products, you are requested to carefully read this document and fully
understand its contents. BM shall not be in any way responsible or liable for failure,
malfunction or accident arising from the use of any BM’s Products against warning, caution or
note contained in this document.
2) All information contained in this document is current as of the issuing date and subject to
change without any prior notice. Before purchasing or using BM’s Products, please confirm the
latest information with a BM sales representative.
●Precaution on using BM Products
1) Our Products are designed and manufactured for application in ordinary electronic
equipments (such as AV equipment, OA equipment, telecommunication equipment, home
electronic appliances, amusement equipment, etc.). If you intend to use our Products in
devices requiring extremely high reliability (such as medical equipment, transport equipment,
traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment
including car accessories, safety devices, etc.) and whose malfunction or failure may cause
loss of human life, bodily injury or serious damage to property (“Specific Applications”), please
consult with the BM sales representative in advance. Unless otherwise agreed in writing by BM
in advance, BM shall not be in any way responsible or liable for any damages, expenses or
losses incurred by you or third parties arising from the use of any BM’s Products for Specific
Applications.
2) BM designs and manufactures its Products subject to strict quality control system. However,
semiconductor products can fail or malfunction at a certain rate. Please be sure to implement,
at your own responsibilities, adequate safety measures including but not limited to fail-safe
design against the physical injury, damage to any property, which a failure or malfunction of
our Products may cause. The following are examples of safety measures:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3) Our Products are designed and manufactured for use under standard conditions and not
under any special or extraordinary environments or conditions, as exemplified below.
Accordingly, BM shall not be in any way responsible or liable for any damages, expenses or
losses arising from the use of any BM’s Products under any special or extraordinary
environments or conditions. If you intend to use our Products under any special or
extraordinary environments or conditions (as exemplified below), your independent verification
and confirmation of product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic
solvents

Notice
[b] Use of our Products outdoors or in places where the Products are exposed to direct
sunlight or dust
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive
gases, including Cl2, H2S, NH3, SO2, and NO2
[d] Use of our Products in places where the Products are exposed to static electricity or
electromagnetic waves
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other
flammable items
[f] Sealing or coating our Products with resin or other coating materials
[g] Use of our Products without cleaning residue of flux (even if you use no-clean type
fluxes, cleaning residue of flux is recommended); or Washing our Products by using water
or water-soluble cleaning agents for cleaning residue after soldering
[h] Use of the Products in places subject to dew condensation
4) The Products are not subject to radiation-proof design.
5) Please verify and confirm characteristics of the final or mounted products in using the
Products.
6) In particular, if a transient load (a large amount of load applied in a short period of time,
such as pulse) is applied, confirmation of performance characteristics after on-board mounting
is strongly recommended. Avoid applying power exceeding normal rated power; exceeding the
power rating under steady-state loading condition may negatively affect product performance
and reliability.
7) De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in
sealed area, confirm the actual ambient temperature.
8) Confirm that operation temperature is within the specified range described in the product
specification.
9) BM shall not be in any way responsible or liable for failure induced under deviant condition
from what is defined in this document.
●Precaution for Mounting / Circuit board design
1) When a highly active halogen us (chlorine, bromine, etc.) flux is used, the residue of flux
may negatively affect product performance and reliability.
2) In principle, the reflow soldering method must be used; if flow soldering method is preferred,
please consult with the BM representative in advance. For details, please refer to BM Mounting
specification
●Precautions Regarding Application Examples and External Circuits
1) If change is made to the constant of an external circuit, please allow a sufficient margin
considering variations of the characteristics of the Products and external components,

including transient characteristics, as well as static characteristics.
2) You agree that application notes, reference designs, and associated data and information
contained in this document are presented only as guidance for Products use. Therefore, in
case you use such information, you are solely responsible for it and you must exercise your
own independent verification and judgment in the use of such information contained in this
document. BM shall not be in any way responsible or liable for any damages, expenses or
losses incurred by you or third parties arising from the use of such information.
●Precaution for Electrostatic
This Product is electrostatic sensitive product, which may be damaged due to electrostatic
discharge. Please take proper caution in your manufacturing process and storage so that
voltage exceeding the Products maximum rating will not be applied to Products. Please take
special care under dry condition (e.g. Grounding of human body / equipment / solder iron,
isolation from charged objects, setting of Ionizer, friction prevention and temperature / humidity
control).
●Precaution for Storage / Transportation
1) Product performance and soldered connections may deteriorate if the Products are stored in
the places where:
[a] the Products are exposed to sea winds or corrosive gases, including Cl2, H2S, NH3,
SO2, and NO2
[b] the temperature or humidity exceeds those recommended by BM
[c] the Products are exposed to direct sunshine or condensation
[d] the Products are exposed to high Electrostatic
2) Even under BM recommended storage condition, solder ability of products out of
recommended storage time period may be degraded. It is strongly recommended to confirm
solder ability before using Products of which storage time is exceeding the recommended
storage time period.
3) Store / transport cartons in the correct direction, which is indicated on a carton with a
symbol. Otherwise bent leads may occur due to excessive stress applied when dropping of a
carton.
4) Use Products within the specified time after opening a humidity barrier bag. Baking is
required before using Products of which storage time is exceeding the recommended storage
time period.
●Precaution for Product Label
QR code printed on BM Products label is for BM’s internal use only.
