Syfer committed to RoHS but still invests in leaded products for exempt sectors

Somewhat against the industry trend, the latest designs of surface mount chip capacitors available from leading UK passive component manufacturer, Syfer Technology, can be supplied with traditional tin/lead terminations.
The devices are destined for equipment in specific industry sectors, including military/aerospace, space and automotive, that are currently exempt from the RoHS directive.

The RoHS Directive is designed to restrict the use of certain materials, including lead, which can be dangerous to the environment. While most industries are finding few difficulties in complying with RoHS requirements, certain sectors are exempt while they investigate a number of reliability issues.

Further, because of the mainstream move towards RoHS compliant components, the supply base for capacitors with tin/lead terminations is dwindling rapidly. Syfer, too, is committed to providing components that meet the RoHS requirements, and already has an extensive range of devices available. The company has a strong environmental policy and its manufacturing operation is already fully approved to ISO 14001, the environmental standard. However, Syfer also recognises that certain applications will continue to require a tin/lead finish, and the company has undertaken to continue to meet this demand.

In fact, Syfer offers the tin/lead finish, with a minimum 10% lead, across a wide range of multilayer ceramic chip capacitors. Devices can be supplied with either a standard silver or a FlexiCap base coat, both with a nickel barrier and the tin/lead finish.
Multilayer ceramic chip capacitors from Syfer are available in a wide range of capacitances, from 0.47pF to 82µF and operating voltages from 16Vdc to 10kVdc, to suit a variety of low or high voltage/current applications.
