Nano-ferrite Material for LTCC Based Transformers and Inductors

NASCENTechnology presented "Nano-ferrite material for LTCC based transfomers and inductors" at the TechConnect World Summits, Conferences and Expo 2011. This conference was held June 13-16, 2011 in Boston, MA.

Reliability Testing on a Multilayer Chip Inductor Fabricated from a Ferrite with a 350 °C Curie Point

As more electronics are used in down-hole energy exploration, under the hood automotive applications, and in other environments where temperatures exceed 200 °C, there is a need for compact passive magnetic components that operate reliability at elevated temperatures. Most ferrites used to make multilayer ceramic inductors have Curie temperatures in the 100-200 °C range. As temperatures rise above...

Planar LTCC Transformers for High-Voltage Flyback Converters

This paper discusses the design and use of low temperature (850 ° to 950 °C) co-fired ceramic (LTCC) planar magnetic flyback transformers for applications that require conversion of a low-voltage to high-voltage (>100-V) with significant volumetric constraints. Measured performance and modeling results for multiple designs show that the LTCC flyback transformer design and construction impose serio...

Integrated Power Electronics Using a Ferrite Based Low-Temperature Co-Fired Ceramic Materials System

This paper discusses a new approach to making hybrid power electronic circuits by combining a low-temperature (850 °C - 950 °C) co-fired ceramic (LTCC) substrate, planar LTCC ferrite transformers/inductors and integrated passive components into a multilayer monolithic package using a ferrite-based LTCC material system. A ferrite tape functions as the base material for this LTCC system. The materia...
