Flame Sensors QFC Pyroelectric Infrared Flame Sensors, Analog Overview Applications KEMET’s QFC pyroelectric flame sensors provide accurate discrimination of flame sources in triple IR flame detection systems, through their excellent signal to noise characteristic at the signature 8 – 10 Hz flicker range of a flame. The sensor element is built into a low noise circuit that has an internal CMOS op amp with a 10 GΩ feedback resistor outputting a voltage signal centred around half the supply rail. Exceptionally high responsivity, a wide field of view and rapid recovery from thermal and electrical shocks makes it the ideal solution for demanding flame detection applications. • Industrial • Oil and gas • Infrastructure protection • Forest protection Benefits • Exceptionally high responsivity • Wide field of view, typically 100° (subject to filter band pass specification) • Rapid recovery from thermal and electrical shock (< 1 second downtime) • TO39 package • Analog output • Integrated op amp Ordering Information USE QFC S A 3381 0 0 Product Family Series Sensor Type Mounting Type Specification Packaging Version QFC = TO39 IR Flame Sensors S = Single K = Evaluation Kit A = Sensor Only 4 = Evaluation Kit Type 4 0000 = Fixed 3381 = 3.38 µm bandpass 3911 = 3.91 µm bandpass 4351 = 4.35 µm bandpass 4481 = 4.48 µm bandpass 4551 = 4.55 µm bandpass 5001 = 5.00 µm cut on 5501 = 5.50 µm cut on 0 = Bulk 0 Sensors One world.

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 © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com SE0210_QFC • 12/13/2019 2 Flame Sensors – QFC Pyroelectric Infrared Flame Sensors, Analog Dimensions – Millimeters Cross Section View Top View Bottom View Field of View FoV across horizontal window aperture FoV across vertical window aperture FoV across diagonal window aperture Note: Normalised polar plots show max FoV achievable along x, y axis and diagonal without any filter applied. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com SE0210_QFC • 12/13/2019 3 Flame Sensors – QFC Pyroelectric Infrared Flame Sensors, Analog Part Number Specifications Sensor Characteristics Filter Aperture Element Size (mm) (µm) 5.2 x 4.2 1 2 1,000 x 1,000 Package Responsivity1 (V/W) D*1 (cm√Hz/W) Noise1 (µV√Hz) Field of View2 TO39 150,000 3.5 x 108 Mean 70 Typical 100° 10 Hz, 500 K, room temperature, without window and optics.

Do not use in water, alcohol ETA, corrosive gas or under sea breeze. Do not be expose to corrosive substances. 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. Precision devices such as this sensor can be damaged or caused not to meet published specification due to ESD. 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. Pyroelectric Infrared Sensors should be stored in normal working environments. Solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long-term storage. KEMET recommends that ambient storage conditions are < 30°C and < 60% relative humidity and that maximum storage temperature does not exceed 110°C. Atmospheres should be free of chlorine and sulfur-bearing compounds. Temperature fluctuations should be minimized to avoid condensation on the parts. For optimized solderability sensors stock should be used promptly, preferably within 24 months of receipt. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com SE0210_QFC • 12/13/2019 5 Flame Sensors – QFC Pyroelectric Infrared Flame Sensors, Analog KEMET Electronics Corporation Sales Offices For a complete list of our global sales offi ces, please visit www.kemet.com/sales.
