Inductors: Multilayer ceramic coils with the highest inductance (TDK-EPC Corporation)

Information contained in the news releases are current as of the date of the press announcement, but may be subject to change without prior notice.

• Inductance of 0603 components increased to up to 180 nH.

August 25, 2011

TDK-EPC, a group company of TDK Corporation, presents the TDK MLG0603S series of multilayer ceramic coils with the world’s highest inductance values*. These 0603 inductors feature an inductance of up to 180 nH at 100 MHz. Mass production started in August 2011.

To increase the inductance, TDK-EPC optimized 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 to100 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 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.

• *As of August 2011, according to TDK investigations.

Glossary

• E24: preferred number series defined by international standard IEC 60063 that subdivides the interval from 1 to 10 into 24 logarithmic steps. Other preferred E-series are E48 and E96, especially for extremely narrow-tolerance resistors.

Main applications

• RF circuits of mobile phones, smartphones, cordless phones, and other mobile communications devices.

Main features and benefits

• Inductance increased to up to 180 nH, the industry’s highest rating for a 0603 component.
• RoHS-compatible and suitable for lead-free soldering.
