An LTCC Transformer is a Low Temperature Co-Fired Ceramic Transformer. The low firing temperature is below the melting point of silver (900° C), it is “co-fired” because the entire transformer structure is fired in a kiln at once, and the ceramic material is a ferrite tape (the windings are silver).
The Transformer is made by screen printing silver winding patterns on magnetic tape. Special non-magnetic insulating materials are also printed. The tape layers are stacked and laminated into structures up to 40 or more layers before being fired in a kiln.
The finished product is a very rugged ceramic core with the windings embedded in the ferrite. It offers multiple advantages:
Maximum Performance: The LTCC Transformer provides millions of charge/discharge fail safe cycles and complete test data is available with each component.
Extremely Robust Structure: LTTC Transformers are Self-shielding, can handle temperatures from -45° C to 250° C, can handle high shock, and can handle high vibration.
Minimum Footprint: LTCC transformers and inductors are flat, thin, lightweight, and approximately one third the volumetric size of wire-wound transformers. There simply is nothing smaller than these LTCC transformer components which embed the coil windings within the magnetic core body.
Multiple Form Factors: Round or odd form factors, alternate co-fired termination styles and positions, and the integration of traditional thick film or LTCC circuits are all possible with LTCC Transformers.
