NEC's NE688 series of NPN epitaxial silicon transistors are
designed for low cost amplifier and oscillator applications. Low
noise figures, high gain and high current capability equate to
wide dynamic range and excellent linearity. NE688's low
phase noise distortion and high fT make it an excellent choice
for oscillator applications up to 5 GHz. The NE688 series is
available in six different low cost plastic surface mount pack-
age styles, and in chip form.

Subject: Compliance with EU Directives
CEL certifies, to its knowledge, that semiconductor and laser products detailed below are compliant
with the requirements of European Union (EU) Directive 2002/95/EC Restriction on Use of Hazardous
Substances in electrical and electronic equipment (RoHS) and the requirements of EU Directive
2003/11/EC Restriction on Penta and Octa BDE.
CEL Pb-free products have the same base part number with a suffix added. The suffix –A indicates
that the device is Pb-free. The –AZ suffix is used to designate devices containing Pb which are
exempted from the requirement of RoHS directive (*). In all cases the devices have Pb-free terminals.
All devices with these suffixes meet the requirements of the RoHS directive.
This status is based on CEL’s understanding of the EU Directives and knowledge of the materials that
go into its products as of the date of disclosure of this information.
Restricted Substance

Mercury < 1000 PPM Not Detected
Cadmium < 100 PPM Not Detected
Hexavalent Chromium < 1000 PPM Not Detected
PBB < 1000 PPM Not Detected
PBDE < 1000 PPM Not Detected
If you should have any additional questions regarding our devices and compliance to environmental
standards, please do not hesitate to contact your local representative.

content of its products represents knowledge and belief as of the date that it is provided. CEL bases its knowledge and belief on information
provided by third parties and makes no representation or warranty as to the accuracy of such information. Efforts are underway to better
integrate information from third parties. CEL has taken and continues to take reasonable steps to provide representative and accurate
information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals. CEL and CEL
suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for
