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.

ECWFE Series
The ECWFE series from Panasonic are metallised polypropylene film capacitors. These film capacitors are compact and feature a flame retardant case with non-combustible epoxy resin. With a durable and robust boxed exterior, these film capacitors are far more capable of withstanding vibration than standard dipped capacitors. With built-in fuse functionality, ECWFE capacitors will not short circuit, but open upon failure. The use of a polypropylene dielectric material ensures better electrical characteristics than a polyester dielectric.
Rated for 450 V dc applications
Polypropylene dielectric
Built in fuse and failsafe design
Non-inductive construction
Excellent frequency characteristics
Low loss
Low hum sound noise
Product Application Information
ECWFE film capacitors are recommended for use in high frequency circuits, high current circuits and active filter circuits. ECWFE polypropylene capacitors are designed for use in the industrial automation, IT and alternative energy industries. Suitable applications include power supplies, PFC, servers and automation equipment where vibration is a concern.
