QFS Pyroelectric Infrared Flame Sensors, I2C-SMD
Overview
Applications
KEMET’sꢀQFSꢀpyroelectricꢀflameꢀsensorsꢀcombineꢀhighꢀ
sensitivity with fast response times and high dynamic range
to ensure rapid and accurate detection of small and large
flames,ꢀnearbyꢀorꢀoverꢀlargerꢀdistances.
• Smart home
• Smart building
• Industrial IoT
• Transportation
These high quality sensors, in their small SMD package,
integrate a digital, current mode read-out offering high
responsivityꢀoverꢀtheꢀfullꢀfrequencyꢀrangeꢀofꢀflameꢀflickerꢀ
from 3 – 30 Hz. Industry standard I2C communication
enables plug-and-play connectivity to microcontrollers and
allows easy tuning and calibration. Programmable gain
andꢀfilteringꢀofferꢀmaximumꢀflexibilityꢀinꢀsystemꢀdesign,ꢀ
andꢀvariousꢀopticalꢀfilterꢀoptionsꢀareꢀalsoꢀavailable.ꢀTheseꢀ
sensors can be connected toegther in linear series to allow
synchronized sampling across devices.
Their long and maintenance-free operational lifetime and
various low power modes makes it ideal for any smart or
IoT type of applications.

Environmental Compliance
All KEMET Flame Sensors are RoHS and REACH Compliant.
Article 33(1) of the REACH Regulation states that manufacturers and importers of articles (products) are required to notify
their customers of the presence of any Substances of Very High Concern (SVHC) in their products exceeding 0.1% by weight
and provide instructions on safe use of the product.
KEMET Corporation reports regarding the Article 33(1) of REACH Regulation as follows:
1. Applicable Product: Flame Sensors (QFC & QFS series)
2. Report for the content of REACH SVHC list:
The product(s) above contains a substance by more than 0.1wt% per product weight that was published in the 8th update of
the REACH SVHC substances (December 19, 2012).
3. Regarding the safety of the flame sensors (Piezoceramic products):
The Piezoceramic that is used in this product becomes ceramic by sintering powder containing PZT as the main ingredient. It
is chemically stable, with minimum risks toward the human body or environment within the intended use of the product. Please
note that risks could occur in the case of inhalation or accidental oral uptake of powder ceramics.
4. Technical product information on the flame sensors (Piezoceramic products):
The manufacturing technique of the “piezoceramic products” whose main ingredient is Lead Titanium Zirconium Oxide (PZT)
has been established, and there is no alternative material that can exhibit superior performance than PZT at this moment.
Please note that the piezoceramic is listed as an exempt on RoHS (2011/65/EU) AnnexIII (7c.1).
5. The responsibility of piezoceramic manufacturers:
Piezoceramic manufacturers report information regarding PZT containment in their products to the customers to obey the
article 33 of the REACH regulation

Handling Precautions
Pyroelectric Infrared Sensors should be kept away from indirect and direct sunlight, the headlights of cars, wind, and
exposureꢀtoꢀstrongꢀvibrationꢀandꢀstrongꢀshock.
Do not use in water, alcohol ETA, corrosive gas or under sea breeze.
Doꢀnotꢀbeꢀexposeꢀtoꢀcorrosiveꢀsubstances.
Do not drop or apply any mechanical stress.
The performance of this device can be affected by ESD. Precautions should be used when handling and installing the
sensor.ꢀPrecisionꢀdevicesꢀsuchꢀasꢀthisꢀsensorꢀcanꢀbeꢀdamagedꢀorꢀcausedꢀnotꢀtoꢀmeetꢀpublishedꢀspecificationꢀdueꢀtoꢀESD.ꢀ
Please note that there is limited ESD protection built-in as the device is optimised for low power consumption and low noise
operation. Human Body Model (HBM), per JS-001: 2,000 V.
The sensor is classed as Moisture Sensitivity Level 3 (MSL-3). The package should be handled according to IPC/JEDEC
J-STD-20.
Pyroelectric Infrared Sensors should be stored in normal working environments.
Solderabilityꢀwillꢀbeꢀdegradedꢀbyꢀexposureꢀtoꢀhighꢀtemperatures,ꢀhighꢀhumidity,ꢀcorrosiveꢀatmospheres,ꢀandꢀlong-termꢀ
storage.
KEMETꢀrecommendsꢀthatꢀambientꢀstorageꢀconditionsꢀareꢀ<ꢀ30°Cꢀandꢀ<ꢀ60%ꢀrelativeꢀhumidityꢀandꢀthatꢀmaximumꢀstorageꢀ
temperatureꢀdoesꢀnotꢀexceedꢀ110°C.ꢀAtmospheresꢀshouldꢀbeꢀfreeꢀofꢀchlorineꢀandꢀsulfur-bearingꢀcompounds.
Temperatureꢀfluctuationsꢀshouldꢀbeꢀminimizedꢀtoꢀavoidꢀcondensationꢀonꢀtheꢀparts.
For optimized solderability sensors stock should be used promptly, preferably within 24 months of receipt.
