MEAN WELL SPU03 series: 3W isolated DC/DC converter - SPU03M-12

Description

SPU03M-12 — 3W isolated DC/DC converter

MEAN WELL SPU03M-12 is a 3 W isolated, unregulated DC/DC converter in a SIP package. It accepts 10.8–13.2 VDC input (12 V nominal) and provides a single 12 VDC output; its specified current range is 25–250 mA. Maintain at least 25 mA output load. Allow for the stated line and load regulation when selecting the downstream circuit.

Output and model selection

Complete model / series SPU03M-12 / SPU03. Input code M: 12 V nominal; output code 12: 12 V single output.
Conversion and rated power Isolated, unregulated single output; 3 W rated power. Rounded current figures do not increase the rated power.
Output voltage and current 12 VDC; 25–250 mA. Maintain at least 25 mA output load.
Efficiency 86% typical.
Voltage accuracy ±2.0%.
Line regulation ±1.2% for 1% input variation; measured from low line to high line at rated load.
Load regulation ±8.0%; measured from 20% to 100% rated load.
Ripple and noise 50 mVp-p maximum; measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Switching frequency 60 kHz minimum.
Specification conditions Normal input voltage, rated load, 25°C and 70% RH, unless otherwise specified.

Input, isolation and protection

Input voltage 12 VDC nominal; operating range 10.8–13.2 VDC.
Input current Full load: 300 mA; no load: 25 mA.
Input filter Capacitor type.
Recommended input fuse An input fuse is recommended. The datasheet does not specify its current rating or response type.
Input/output withstand voltage 3 kVDC input to output.
Isolation resistance 100 MΩ between input and output, tested at 500 VDC, 25°C and 70% RH.
Isolation capacitance 80 pF maximum.
Overload and short circuit Momentary only. The catalog labels the protection type as “Broken” for both overload and short circuit. Do not rely on continuous fault protection or automatic recovery.

Environment, reliability and compliance

Operating temperature and derating −40 to +90°C, subject to the derating curve. This 12 V version has full load through +85°C; above that temperature, reduce load according to its curve while staying within the +90°C working limit.
Cooling Free-air convection.
Working humidity 20–90% RH, non-condensing.
Storage temperature and humidity −40 to +105°C; 10–95% RH.
Temperature coefficient ±0.03%/°C over 0–50°C.
Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each of the X, Y and Z axes.
Safety standards EAC TP TC 020/2011 approved, as listed in the datasheet.
EMC emission Compliance with BS EN/EN55032 Class B, FCC Part 15 Class B and EAC TP TC 020, as listed in the datasheet.
EMC immunity Compliance with BS EN/EN61000-4-2, -3, -4, -5, -6 and -8; light-industry level, criteria A; EAC TP TC 020.
MTBF 700,000 hours minimum, MIL-HDBK-217F at 25°C. This is a reliability estimate, not a service-life or warranty duration.
Production test 100% full-load burn-in test.
Warranty 2 years, as stated in the datasheet.

Mechanical details and packing

Construction Internal SMD technology; built-in EMI filter; non-conductive plastic single-in-line case. The manufacturer describes the series as low cost and high reliability.
Dimensions 19.6 × 7.5 × 10.2 mm (L × W × H).
Pin assignment Bottom view: pin 1 +Vin; pin 2 −Vin; pin 5 −Vout; pin 7 +Vout.
Pin geometry 2.54 mm spacing between pins 1 and 2; 5.08 mm between pins 5 and 7; 3.81 mm lead extension; 0.5 mm stand-off; 1.2 mm pin-row offset. Pin section: 0.50 × 0.30 mm with ±0.05 mm tolerance. Use the dimensioned drawing for PCB layout.
Unit weight 2.9 g per unit, as listed in the packing specification.
Standard packing 25 pieces per tube; 160 tubes and 4,000 pieces per carton. Tube gross weight: 100 g; carton gross weight: 16.8 kg. These are standard packing references, not the quantity supplied with an individual product order.
