Murata announced it has introduced the NXJ1, a series of single-output, high-reliability, high-isolation, 1-W surface-mount DC/DC converters designed for medical products, with other applications in industrial, transport, and telecom markets. Manufactured by Murata Power Solutions and measuring 13.72 x 10.46 x 4.36 mm, this compact low-profile series features six models comprising nominal input voltage options of 3.3, 5, or 12 VDC and single outputs of 3.3, 5, 12, or 15 VDC.
The NXJ1 series is manufactured using an automated process that also fabricates an integrated transformer into the substrate. These techniques contribute to increasing product reliability and repeatability of performance in a halogen free, inspectable land grid array (iLGA) package. The industry-standard footprint is compatible with previous models, making it suitable for replacement in existing applications as well as for new space-constrained low-profile designs. The converter features short-circuit protection, and agency recognition is pending to the UL60950 standard for reinforced insulation and 4.2-kV high-pot test.
With its approvals to the rigorous medical safety standards ANSI/AAMI ES60601-1, with 2 MOOP and 1 MOPP recognition pending, the surface-mount isolated NXJ1 is suited to medical applications.
Product manager Ann-Marie Bayliss at Murata commented, “With UL60950 for reinforced insulation and ANSI/AAMI ES60601-1, 2 MOOPs pending, the NXJ1 offers enhanced features previously not available in a miniature low profile surface mount product.”
The device can operate across the full industrial temperature range from -40 to +85°C. It has an MSL 2 rating and is compatible with a peak reflow solder temperature of 245°C as per J-STD-020 and J-STD-075.
