TDR 3-4812SM

The TDR 3SM series is a family of compact 3 W DC/DC-converters with 2:1 input voltage ranges and tightly regulated output voltages even under no load conditions. The product is available in SMD-package. They work with high efficiency over the full load range and come with a remote On/Off input. The usability in temperature ranges of up to 85°C, continuous short circuit protection and excellent immunity against environmental influences make these converters very reliable. A TDR 3SM converter is the ideal solution for space critical high end applications in communication equipment, instrumentation and industrial electronics.

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.
