TDK introduced the CLF7045NI-D wirewound SMD, a new addition to its CLF-NI-D series of power inductors. The CLF7045NI-D power inductors feature a wide temperature range from -55°C to 150°C and offer 1.0μH to 470μH (E6 series) rated inductance. The 7.4mm x 7mm x 4.5mm power inductors are available for rated currents of 0.41A to 8.5A and offer 9mΩ to 1.20Ω DC resistance.

Compliant to AEC-Q200, the new components offer outstanding heat resistance, thanks to TDK's advanced materials technology. A new bonding process for the terminals enables a solderless structural design that features competitive mechanical strength. The new inductors are designed for applications in demanding automotive environments such as the power supply circuits of engine control modules (ECM) and ECUs for airbags, ABS and headlights.

The new CLF7045NI-D types with a 7mm form factor complement the recently introduced 6mm square CLF6045NI-D types. In the future, TDK will further expand the CLF-NI-D series with 5mm, 10mm and 12.5mm square types in order to offer a broad line-up of power inductors that are suitable for a wide range of applications.

Mass production of the CLF7045NI-D power inductors will be launched in August 2015.
