High-value inductors

28 September 2011 Passive Components

TDK-EPC has introduced the TDK MLG0603S series of multilayer ceramic coils with high inductance values of up to 180 nH at 100 MHz.

To increase the inductance, TDK-EPC optimised the coil electrode design and achieved a greater number of thinner layers through improvements in materials and process technologies. As a result, the existing lineup of products, which previously offered inductances up to 100 nH, was expanded with the addition of six new components with inductances ranging from 110 to 180 nH. The 0603S series lineup now includes 62 components (E24 series) with DC resistance values ranging from 0,1 to up to 8,5 Ω, rated currents from 50 to 600 mA, and inductances from 0,3 to 180 nH.

The ceramic coils have an operating temperature range of -55°C to +125°C and are designed for use in the RF circuits of mobile communications devices such as mobile phones and smartphones. They are also suitable for use in other RF signal circuits such as those found in Bluetooth devices.
