Heraeus H540S Micro-heater

The Heraeus H540S is a platinum micro-heating element that is the perfect choice for applications where a tiny, yet accurate heat source is required.  The heater consists of a 12 ohm platinum thin-film structure mounted on a thin ceramic substrate just 5.2 x 3.9 wide (just 1mm thick).

The H540S can be used to heat solids, liquids or gases with high accuracy and a short reaction time.  So they can used to heat biopsy and tissue samples for medical analysis where a very localised heat-source is required.  These micro-heaters offer long-term stability and excellent precision over a wide operating temperature range.

Already utilised in the e-cigarette and vaping markets, custom formats and combination heater/sensors are available for similar high volume applications.
