Latest in circuit protection plus transformers and more

Mouser offers the latest innovations from Bourns from automotive sensors, circuit protection solutions, microelectronic modules, precision potentiometers and resistive products. The company hosts a growing collection of Bourns eBooks, resources and other technical content.

Bourns PLN planar transformers are forward converter transformers designed for 48W to 70W PoE industrial applications, that need a low profile with a high-power density, like BMS. These transformers operate at a switching frequency of 250kHz and voltages from 5V to 12V with an output current from 4A to 14A, making them excellent for power management and LED lighting applications.

For high voltage applications, the Model BID IGBTs, combine technology from a MOSFET gate and a bipolar transistor for high voltage/high current applications like SMPS, UPS and PFC. The Model BID IGBTs are thermally efficient, using advanced trench-gate field-stop technology to deliver greater control of dynamic characteristics, producing lowered collector-emitter saturation voltage and fewer switching losses.

The MF-ASML/X low-resistance PPTC resettable fuses use a proprietary freeXpansion design to improve performance with higher hold currents, higher voltages, and improved resistance stability in a small (0402) footprint. Created to protect against overcurrent and overtemperature events within space-constrained mobile applications, such as battery charging and USB port protection, the fuses deliver plug-and-play protection for PC motherboards as well.

For high-temperature environments, the MF-FSHT PTC resettable fuses offer a 12V voltage rating, up to 40A input current rating, and a low profile (0603) design. MFFSHT fuses provide surface mount packaging for automated assembly, a maximum operating temperature rating of +125C, and low thermal derating factor. The freeXpansion design improves fuse performance, making them excellent for industrial and other demanding applications needed to operate at elevated temperatures.
