APPLICATIONS The D_NXT-1W series are specially designed for applications where a group of polar power supplies are isolated from the input power supply in a distributed power supply system on a circuit board. These products apply to: 1)Where the voltage of the input power supply is fixed (voltage variation≤±10%); 2) Where isolation is necessary between input and output (isolation voltage ≤±1000VDC); 3) Where the regulation of the output voltage and the output ripple and noise are not demanding. Such as:purely digital circuits , ordinary low frequency analog circuits and IGBT power device driven circuits, etc. ISOLATION SPECIFICATIONS Item Test Conditions Min. Typ. Max.

RECOMMENDED CIRCUIT RECOMMENDED REFLOW SOLDERING PROFILE Remark: The curve applies only to the hot air reflow soldering TYPICAL CHARECTERISTICS EXTERNAL CAPACITOR TABLE (TABLE 1) 1) Requirement On Output Load To ensure this module can operate efficiently and reliably, a minimum load is specified for kind of DC/DC converter operation, make sure in addition to the specified range of a maximum input voltage is load (namely not exceeded, load could not be less than 10% of the full load. If the actual output power full this load). During the minimum output is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load, or use our company products with a lower rated output power (D-NXT -W2/W5). 2) Recommended testing circuit If you want to further decrease the input/output ripple , an "LC" filtering network may be connected to the input and output ends of the DC/DC converter , see (Figure1). It should also be Filtering network should be noted that the staggered with the DC/DC However , the capacitance of the output filter too big , a startup problem might inductance capacitor and the frequency frequency to must proper . If be of avoid mutual the "LC" interference. the capacitance It's not recommended to connect any external capacitor in the application field with less than 0.5 watt output. is arise . For every channel of output,provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1). 3) Output Voltage Regulation and Over-voltage Protection Circuit The simplest device for output voltage regulation , over-voltage and over-current protection is a linear voltage regulator with overheat protection that is connected to the input or output end in series (Figure2). 4) Overload Protection Under normal operating conditions , the protection against overload . The simplest method output is circuit of these to connect a self-recovery products fuse has no in series at the input end or add a circuit breaker to the circuit. 5) Cannot use in parallel and hot swap http://www.microdc.cn Technical Enquiries-Email:[email protected] Tel:0086-20-86000646 Page 2 of 3 D-NXT-1W Series OUTLINE DIMENSIONS& RECOMMENDED FOOTPRINT MECHANICAL DIMENSIONS RECOMMENDED FOOTPRINT Note: Unit: mm[inch] Pin section tolerances: ± 0.10mm[ 0.004inch] General tolerances: ± 0.25mm[ 0.010inch] TUBE OUTLINE DIMENSIONS REEL PACKING OUTLINE DIMENSIONS Note: Unit: mm[inch] General tolerances:±0.50mm[± 0.020inch] L=530mm[20.866inch] Devices per tube quantity: 28pcs L=220mm[8.661inch] Devices per tube quantity: 10pcs Short tube inner package dimensions : L*W*H= 255*170*80mm Short tube outer package dimensions(with six inner package boxes): Note: L*W*H= 375*280*270mm Unit :mm[inch] Long tube inner package dimensions : L*W*H= 580*200*100mm General tolerances: ±0.50mm[ 0.020inch] Long tube outer package dimensions(with two inner package boxes): Per reel of packing quantity:400pcs L*W*H= 600*215*220mm Inner package Long tube outer package dimensions(with three inner package boxes): Tube Quantity : 800pcs L*W*H= 600*215*325mm Outer package carton dimensions: L*W*H=390*360*245mm carton dimensions: L*W*H=365*350*105mm Tube Quantity:1600pcs RoHS COMPLIANT INFORMATION This series is compatible with RoHS soldering systems with a peak wave solder temperature of 300°C for 10 seconds.
