Key Features
- Regulated DC-DC power supply module with 12 V nominal (10.8 V to 13.2 V) input range and dual-output capability including a -12 V secondary rail
- 65% conversion efficiency with UL approval, making NMJ1212SC suitable for safety-certified industrial and medical power subsystems
- Integrated module construction eliminates external magnetics design, shortening time-to-market for 12 V bus powered analog and mixed-signal board designs
Applications
The NMJ1212SC is used in industrial automation controllers, analog signal conditioning boards, and medical instrumentation that require a regulated -12 V supply generated from a 12 V system bus. Its module format with UL approval simplifies safety certification for equipment where a dual-polarity analog power rail must coexist with a 12 V digital supply.

Frequently Asked Questions
What input voltage range does the NMJ1212SC accept and what output voltages does it provide?
The NMJ1212SC accepts an input voltage range of 10.8 V to 13.2 V, with a nominal input of 12 V. It provides a regulated output that includes a -12 V secondary rail, making it a dual-output DC-DC module suitable for analog circuits requiring split power supplies on a single 12 V input bus.
Which safety certification does the NMJ1212SC carry, and what efficiency should designers plan for in their thermal budgets?
The NMJ1212SC carries UL approval for safety-certified designs. Designers should budget for 65% conversion efficiency, meaning 35% of input power is dissipated as heat. At a 12 V nominal input, thermal management planning is required for enclosures with limited airflow, especially when the module operates near full load in industrial or medical equipment.
How does choosing the NMJ1212SC module reduce design effort compared to building a discrete -12 V regulator from a 12 V bus?
The NMJ1212SC integrates the transformer, switching controller, and rectification into a single module, eliminating the need to design custom magnetics, select discrete switching FETs, or calculate loop compensation for a -12 V rail from a 10.8 V to 13.2 V input. This integration shortens schematic complexity and PCB layout effort while delivering a UL-approved, tested power solution with 65% efficiency.
