Vishay Intertechnology introduces a new resonant transformer for inductor-inductor-capacitor (LLC) applications that features both the transformer and an integrated inductor in a single package. Designed to save PCB space while simplifying layouts and reducing component mounting requirements, the 5.5 kW Vishay Custom Magnetics MRTI5R5EZ offers fully tunable magnetizing and leakage inductance with minimal parasitic variation.
- The MRTI5R5EZ is the first transformer of its kind to utilize a second middle transformer leg to complete the resonant inductor portion of the circuit
- Other implementations require an additional magnetic core to deliver the same performance
- Not only does this unique construction save space, but it also simplifies designs by eliminating the need for interconnects or jumpers from the resonant inductor to the transformer’s winding
- The transformer’s losses can be moved from the core to the coil as needed to deliver the best performance and heat dissipation
The Key Specifications:
- Frequency: 100 kHz to 350 kHz
- Rated power: 4 kW to 6 kW
- Rated current: 17 A to 28 A
- Leakage inductance: 6.2 µH to 12 µH
- Magnetizing inductance: 25 µH to 74 µH
- Size (L x W x H): 88 mm by 102 mm by 56 mm
