HIS20smd
Thermal infrared emitter in standard 3x3 mm² SMD, gold plated
HISsmd series emitters are small, powerful infrared radiation
sources that meet the demands for reliable miniaturized gas
sensors and offer a wide range of new application scenarios.
The low energy consumption, the high efficiency and the small
size allow the use in portable, battery-powered, and mobile applications. These innovative infrared light sources are used, forinstance, in respiratory gas analysis, e.g. for the detection of
CO₂ and breath alcohol, and in Smart Home and Smartphone
applications.

The pioneering SMD package enables a fully automated production in high-volume markets.
Infrasolid’s infrared radiation sources are pulsable thermal
emitters with a near black-body emittance. Based on a patented nanotechnology and a patented emitter set-up made of ahigh-melting metal, the free-standing monolithic radiating element and the nanostructured emitter surface offer numerous
advantages in many applications.

Key features
Pulsable thermal black-body infrared source
mounted in a SMD package with a size of 3x3 mm².
Patented nanostructured radiating element
achieves up to 500% more detection signal!

Breakout board:

For evaluation purposes we offer a breakout board (BOB)
wich can be used to easy connect drivers and electronics forevaluation.

012 cmAll our IR sources can be driven in electrical voltage, current orpower regulated mode. The application decides whether the operating mode is DC or AC (pulsed). Depending on the drive modeand the applied electrical power the electrical resistance of the IR
emitter can change over time. For highest measurement accuracy
a power regulated mode is always recommended for thermal IRemitters. However, it is the most complex operating mode and notsuitable in all applications.

For applications that require a small and low-cost driving circuitwith a maximum stability we have a technical note with an adjustable low dropout voltage (LDO) regulator.
