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:

PBB (Polybrominated Biphenyls)0.1%
PBDE ( Polybrominated Diphenyl Ethers)0.1%
Hexavalent Chromium0.1%
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

Thyristors - DYNEX

A Thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. They act as bistable switches, conducting when their gate receives a current trigger, and continue to conduct while they are forward biased. Thyristors are synonymous to Silicon-Controlled Rectifier (SCR).
