TDK-EPC has developed the new MLG0402Q series of multilayer ceramic coils in 0402 with a Q factor of 15,8 at 1 GHz and 10 nH. They are chip components with a compact 0402 size (0,4 × 0,2 × 0,2 mm).
Their excellent Q factor was achieved by employing a new technology that increases the precision of position control when forming the layers, thus allowing an optimisation of the coil design. The high Q factor means that efficiency is high with low loss, particularly when the coil is used in high-frequency circuits.
The lineup of the E12 series comprises 15 components with low resistance ranging from a maximum of 0,4 to 2,6 Ω, a rated current of 100 to 250 mA, and an inductance ranging from 1 to 15 nH. In addition, TDK-EPC plans to introduce an E24 series with 12 further inductance values in the near future. These components have an operating temperature range of -40°C to +85°C and are designed for use in the high-frequency circuits of mobile communications devices. They are also suitable for use in other high-frequency wireless signal circuits such as those found in Bluetooth devices.
