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
Murata SMD Common Mode Chokes
Murata 1206 DLW31S Series SMD Common Mode Chokes
DLP31S series common mode choke coil chips with high impedance in a small package. The DLP31S series utilise ferrite material technology and film processing technology to give excellent performance at high frequency ranges and is suitable for differential signal line application.
Small size, low profile, SMD. 3.2x1.6x1.15mm (Tolerance: +-0.15mm)
High common mode impedance (550 ohm at 100MHz typ.) in small size
Suppresses high frequency noise that was unable to be suppressed with existing common mode choke coils
Suitable for differential signal lines like USB, because DLP31S does not provide distortion to high speed signal transmission due to its high coupling (coupling coefficient: 0.98 min.)
Applications
USB lines of PCs, peripheral equipment
LVDS lines of Note-PCs, LCDs
USB lines of digital AV equipment such as digital cameras
