Conformity
REACH Declaration

TRACOPOWER products do not generally fall under the REACH directive. 
Our general REACH declaration is available via the following link: 

General REACH declaration

RoHS Compliance

TRACOPOWER completed successfully in July, 2006 the process of producing all power supply and dc/dc converter fully compliant to the European RoHS Directive (2002/95/EC). Excepted are those products which have been removed from the actual sales program (obsolete products).
The EU RoHS Directive and the China RoHS both denominate identical Substances and MCV’s (Maximum Concentration Values).
The current TRACO POWER RoHS declaration therefore satisfies the EU RoHS Directive as well as the China RoHS Regulation.

Directive 2011/65/EU

TRACOPOWER RoHS Declaration

Moisture Sensitivity Level

All TRACOPOWER surface mount devices (SMD) are qualified for lead-free reflow solder process under the condition that the product is handled in accordance (J-STD-033B) to its moisture sensitivity level (IPC/JEDEC J-STD-020D.1).

Cleaning Guideline

We generally do not recommend washing or cleaning electronic components. You should avoid it, if it is not absolutely necessary. Please refer to cleaning guide.
