Murata Power Solutions NMK DC/DC Converter 5V DC 400mA Output 13.2V DC Max Input 10.8V Min Input 2W SIP Package NMK1205SAC

Murata Power Solutions NMK1205SAC DC/DC Converter delivers a regulated 5V DC output at 400mA from an input range of 10.8V to 13.2V DC, powering applications requiring up to 2W in a compact SIP (Single Inline Package) form factor. Designed for industrial temperature ranges from -40°C to 85°C, this converter provides robust and reliable performance for electronic component power supplies.

The converter utilizes a through-hole mount design for straightforward PCB installation and incorporates a fully encapsulated construction with toroidal magnetics, eliminating the need for electrolytic or tantalum capacitors. It features a high 3kV DC isolation voltage for enhanced safety and low ripple and noise (30mV peak-to-peak), resulting in clean, stable output power.

With a high efficiency of 83% and a power density of 1.31 W/cm³, the NMK1205SAC efficiently manages thermal dissipation without requiring a heatsink. Its compact dimensions (19.5 mm length, 19.6 mm width, and 10 mm depth), coupled with a lightweight package weighing approximately 2.8 g, make it suitable for space-constrained industrial electronic designs.

The converter is compliant with RoHS directives and uses UL 94V-0 rated flame-retardant materials for increased safety standards. It suits diverse industrial applications including power supplies in instrumentation, telecommunications, industrial automation, and embedded systems where reliable DC/DC conversion is critical.

Additional features include an MTBF of over 3.5 million hours, supporting long-term operation and minimal maintenance requirements. The NMK series provides an excellent power upgrade from the 1W NMV series, with superior output voltage accuracy and load regulation.

Supports input voltage range from 10.8 V to 13.2 V DC. Provides 5 V DC output at 400 mA current. Through-hole SIP package with 7 pins. Maximum operating temperature 85°C and minimum -40°C. Isolation voltage of 3kV DC for one minute.

Low ripple and noise at 30 mV peak-to-peak. High efficiency at 83% with no heatsink required. RoHS compliant with UL 94V-0 package material. Explore other DC/DC Converters and power supply components in the Electronics & Electricals category on EnvMart for complementary products and solutions.
