The Driver Circuit Board supports a quick evaluation of our IR emitters and can be ordered as single component (without IR emitter) or assembled with an IR emitter of the HISsmd series. Only a supply voltage and a pulse signal have to be applied to the 3-pin Molex PicoBlade 1.25 mm connector. For more information about its function, see our technical note.
The Breakout Board transfers the SMD footprint to 2.54 mm headers and can be ordered as single component (without IR emitter) or assembled with an IR emitter of the HISsmd series.
All our emitters comply with the following JEDEC-standards:
(temperature cycling and shock test: -45 °C / + 90 °C, 100 cycles)
(vibration test: log. sweep 20 Hz…2000 Hz, peak 20 g, X/Y/Z direction)
(drop test: 5000 m/s², 6 directions)
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, for instance, 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 a high-melting metal, the free-standing monolithic radiating element and the nanostructured emitter surface offer numerous advantages in many applications.
