OKR-T/3 Series www.murata-ps.com Adjustable Output 3-Amp SIP-mount DC/DC Converters PRODUCT OVERVIEW The OKR-T/3 series are miniature SIP non-isolated Point-of-Load (PoL) DC/DC power converters measuring only 0.41 x 0.65 x 0.22 inches (10.4 x 16.5 x 5.6 mm). The wide input range is 4.5 to 14 Volts DC. Based on 600 KHz synchronous buck topology, the high power conversion efficient Point of Load (PoL) module features programmable output voltage and On/Off control, under voltage lock out (UVLO), overcurrent and over temperature protections. These units meet all standard UL/EN/ IEC 60950-1 safety certifications and RoHS-6 hazardous substance compliance.

Wide Input Voltage Range W12 = 4.5 – 14 Volts Maximum Rated Output Current in Amps Product Label Because of the small size of these products, the product label contains a character-reduced code to indicate the model number and manufacturing date code. Not all items on the label are always used. Please note that the label differs from the product photograph on page 1. Here is the layout of the label: Mfg. date code XXXXXX Product code YMDX Rev. Revision level Figure 2. Label Artwork Layout Model Number OKR-T/3-W12-C Product Code R01103 The manufacturing date code is four characters: First character – Last digit of manufacturing year, example 2009 Second character – Month code (1 through 9 and O through D) Third character – Day code (1 through 9 = 1 to 9, 10 = O and 11 through 31 = A through Z) Fourth character – Manufacturing information The label contains three rows of information: First row – Murata Power Solutions logo Second row – Model number product code (see table) Third row – Manufacturing date code and revision level www.murata-ps.com email: [email protected] 30 Oct 2009 MDC_OKR-T/3-W12.A02_short Page 2 of 3 This data sheet contains core information only.
