Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
R-78Cxx 1.0L Series Single Output DC/DC Converter
The Recom R-78Cxx series are highly efficient, non-isolated switching regulators are ideally suited to replace the 1 Amp 78xx linear regulators, as well as being pin compatible.
The convertor has a high-voltage input range and there is no need for heat sinks, due to little energy being wasted. It has a wide input range with short circuit protection and thermal shutdown.
Note
MTBF to MIL-HDBK 217F
Power derates above 68°C
Features and Benefits
• Low profile
• Pin compatible with LM78xx linear regulators
• High efficiency, non-isolated, no need for heatsinks
• Fully protected for short circuit
• Positive to negative convertor
• Low ripple and noise
