PRODUCT DATA SHEETJSIR 340-5

Economy MEMS C-MOSI® based infrared emitterfor cost effective high volume NDIR gas sensing
applications like home & building automation.

PRELIMINARY

The combination of MEMS standard technologies with CMOS compatible hot-plate
resistance layer enables the production at high qualified but ordinary MEMS Fabproduction lines.

This is the opener for high volume and cost sensitive applications. The emitter's MEMS chips with focus of cost efficiency
and low thermal time constant are developed by our supplier CMOS IR. Despite the focus on mass production and mass
production applications, the emitter impresses with its high radiant power at hot plate temperatures of up to 800 °C
and short time constants.
JSIR 340 sources are available in TO packaging versions with cap or SMD package. The focus on SMD packages enables
an effective automatic assembly process for our customers.
