Multilayer ceramic chip coil is smallest

9 August 2006 Passive Components

TDK's new MLG0402 chip coils are claimed to be the industry's smallest multilayer ceramic chip coils. The inductors, designed for ultra high frequency, represent a major breakthrough in miniaturisation with approximately 70% less volume and 55% less mounting area than the 0603-sized coils currently in widespread use.

The components also offer a superior inductance range, up to a maximum of 12 nH.

In conjunction with the rapid miniaturisation of mobile communications devices such as cellphones as well as the incorporation of multiple functions, there have been strong demands for chip coils to be made more compact. TDK has used multilayering technologies to deliver the MLG0402 series which comprises 14 products with inductances from 1,0 nH to 12 nH.

The MLG0402 chip coils measure 0,4 x 0,2 x 0,2 mm (all dimensions ±0,02 mm) with tolerance of ±0,3 nH and ±5%, and operating temperature range -55 to +125°C. The components are lead-free.
