About Us

Established in 1984, NAKAGAWA Electronics Limited (NKG) has been a trusted provider of world-class frequency control products and services. Our team of passionate engineers and marketing specialists excels in delivering superior quality and expert knowledge in the electronics industry. With an efficient supply chain and a track record of meeting customer expectations, we are proud to serve a diverse range of industries.

Our product range includes quartz crystal and ceramic resonator components, crystal oscillators, and precision instruments like voltage-controlled crystal oscillators (VCXO), temperature-compensated crystal oscillators (TCXO), and high-stability crystal oscillators (OCXO).

Quality Assurance

We are committed to delivering products that exceed the customer’s expectations by implementing the following system requirements:

Our Hong Kong HQ operates under ISO 9001 and 14000. Our manufacturing sites operate under advanced standards by utilizing additional systems such as TS 16949. We follow the aims of the electronic industry code of conduct (EICC – today by RBA). Manufacturing sites have passed corresponding EHS audits.

We are committed to the restricted use of conflict metals and routinely inspect our suppliers in order to verify non-use of restricted sources.

Engineering Support

Professional engineering personnel with over 30 years of experience in the field. We offer advanced board testing capability for customer applications. These include:

  • Frequency matching test to ensure crystal works at the desired frequency
  • Determination of circuit’s negative resistance and circuit margin
  • Determination of drive level that oscillator provides for the crystal

Product Environmental Compliance

  • We offer RoHs compliant products since 2004, majority fully compliant
  • Exemption 7(a) for Pb contained in high melting point solder alloy, used in certain types of SMD tuning fork crystals and special high- end oscillators for telecom
  • Exception 7(c) for Pb contained in piezoelectric devices (used in ceramic resonators and filters) and in glass compound (used in glass seal SMD crystal)
  • Our products are halogen-free per IPC J-STD-709, verified since 2008
  • We are continuously monitoring for updates of REACH’s list of SVHC’s in order to ensure that all our products remain compliant
  • In 2008 we obtained confirmation that all our products be of PFOS/PFOA
  • None of our products use PVC or phthalates in plastic-like encapsulations
  • Our environmental compliance extends to packaging materials
  • In-hours XRF testing is mandatory at all our manufacturing sites
