The Murata NXJ family comprises surface-mount isolated non-regulated DC–DC converters. Leveraging patented Block-Coil transformer technology, they achieve compact packaging, high isolation voltage, high common-mode transient immunity (CMTI), low isolation capacitance and low leakage current. Designed for industrial automation, medical equipment, energy storage, automotive applications, and signal isolation power supply for humanoid robots, providing isolated power supplies for CAN, I²C, SPI and other isolated interfaces, as well as analogue front-end acquisition circuits. The NXJ1T (1W reinforced insulation version), NXJ1 (1W standard version) and NXJ2 (2W power upgrade) form a comprehensive power range; all are SMD-mounted and suitable for large-scale automated production.

I. NXJ1T Series | 1W Reinforced Insulation Isolated DC–DC Converter

The NXJ1T is the high-end reinforced insulation model in the NXJ family, featuring high voltage withstand capability, extremely low isolation capacitance and low leakage current. It is primarily targeted at high-safety-level applications in the medical sector, high-voltage energy storage and 800V automotive platforms.

Key Specifications

Rated power: 1W, single-channel unregulated output

Input specifications: Standard 5V input (4.5–5.5V)

Isolation withstand voltage: 4200VDC (1s 100% production line inspection), continuous insulation 400Vrms, reinforced insulation 200Vrms

Package Dimensions: 10.55 × 13.70 × 4.04 mm SMD moulded package

Switching Frequency: 1.5 MHz, typical efficiency 76%–80%

CMTI > 200 kV/μs, with extremely low isolation capacitance, significantly suppressing common-mode leakage current

Protection functions: Undervoltage lock-out (UVLO), short-circuit protection; operating temperature range: –40°C to +125°C; reliability verified through 1,000 high-low temperature cycles

Safety certification: UL 62368-1; supports ANSI/AAMI ES60601-1 medical 1MOPP safety requirements

Typical Applications

Medical ultrasound and surgical instruments; energy storage systems (BESS) and photovoltaic inverters; CAN-isolated power supply for 800V on-board vehicle charging points; industrial high-voltage sensor data acquisition; suitable for isolated signal power supplies in humanoid robot joint actuators, isolating noise interference between the main control and power sides.

II. NXJ1 Series | 1W Basic Isolated DC–DC Converter

The NXJ1 is the entry-level 1W version in the family, pin-compatible with the NXJ1T. It features basic insulation for isolation, offering a more cost-effective solution suitable for general-purpose industrial isolated power supplies where medical-grade reinforced insulation is not required.

Key Parameters

Rated power: 1W single-channel unregulated output

Input options: 5V, 12V, 24V; multiple input versions available

Isolation Voltage: 3000 VDC basic insulation

Package: Fully compatible with the NXJ1T; SMD 10.55 × 13.70 × 4.04 mm; identical pinout, allowing direct hardware interchangeability for evaluation

Typical efficiency: 74–78%; built-in short-circuit protection; operating temperature range: –40 °C to +105 °C

MSL-2 moisture sensitivity level, halogen-free, suitable for automated reflow soldering and surface-mount assembly

Typical Applications

Industrial PLC isolation interfaces, RS485/CAN bus isolation power supplies; industrial sensor modules; servo control boards; isolation auxiliary power supply for humanoid robot I/O boards; signal isolation circuits for instruments and meters.

III. NXJ2 Series | 2W High-Power Isolated DC–DC Converter

The NXJ2 increases the output power to 2W, features an iLGA-inspected SMD package with visible solder pads, and undergoes 5200 VDC withstand testing across the entire production line. With its higher power output, it is suitable for isolated interfaces and analogue circuits with higher power consumption.
