Product Description
The Murata Power Solutions OKI-78SR-5/1.5-W36HE-C is a non-isolated DC-DC converter engineered for embedded and commercial electronics. Featuring a fixed 5V output voltage and supporting up to 1.5A of current delivery, this module is designed to provide tight regulation and high efficiency directly at the site of power usage. With a maximum input voltage of 36V DC and a minimum of 7V, it is highly compatible with a variety of applications.
This converter is constructed in a TO-220 package for through-hole mounting, allowing for easy integration into control boxes and ITE commercial devices. The compact footprint, measuring just 18mm in length, 11.9mm in width, and 9.5mm in depth, ensures minimal space consumption while delivering robust electrical performance.
Efficiency is a standout feature, achieving up to 90.5% with low ripple and electrical noise (75mV peak-to-peak), eliminating the need for external components or heatsinks. Outstanding thermal derating and short circuit protection enhance reliability, making it suitable for harsh environments with operating temperatures from -40°C to 85°C.
Additional benefits include vertical SIP or horizontal mounting flexibility, RoHS-compliant construction, and a very high MTBF of 78,700,000 hours for sustained industrial performance. Line and load regulation are tight at ±0.3% and ±0.4% respectively, maintaining stable operation under varying conditions.
Common applications include use in embedded systems, commercial instrumentation, and industrial control boxes. The converter’s plug-in design directly replaces traditional linear regulators, streamlining setup and maintenance routines.
