Model selection and output

Complete model / series	SBTN01L-12SC / SBTN01. Input code L: 5 V nominal; output code 12: 12 V. SC identifies the optional continuous-short-circuit version.
Conversion and rated power	1 W rated. Rounded current values do not increase the rated power; observe the current window and thermal limits.
Output voltage and current	12 V DC; 8.4–84 mA. The lower current value is the specified minimum load.
Efficiency	80% typical; at normal input, rated load, 25°C and 70% RH.
Series efficiency reference	The SBTN01 feature page states efficiency up to 84%; use this model's typical efficiency above for selection.
Maximum capacitive load	220 µF.
Voltage accuracy	±2.0%.
Ripple and noise	75 mVp-p. Measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Line regulation	1.2% for 1% input variation; measured from low line to high line at rated load.
Load regulation	±8%; measured from 10% to 100% rated load.
Switching frequency	100 kHz typical.
Specification conditions	5 V DC normal input, rated load, 25°C and 70% RH, unless otherwise specified.

Input, protection and isolation

Input voltage	5 V DC nominal, ±10%; operating range 4.5–5.5 V DC.
Input current	No load: 30 mA; full load: 257 mA. The general specification conditions apply.
Input filter	Internal capacitor.
Recommended input fuse	750 mA slow-blow fuse recommended.
Internal power dissipation	500 mW.
Input surge voltage	9 V DC for 100 ms maximum. This is a surge limit, not the continuous operating range.
Short-circuit protection	Continuous short-circuit protection for the optional SC version.
Input/output withstand voltage	1.5 kV DC between input and output. The series offers an optional 3 kV DC isolation version; confirm its ordering details separately. This listing retains the standard 1.5 kV DC rating.
Isolation resistance	100 MΩ between input and output; at 500 V DC, 25°C and 70% RH.
Isolation capacitance	80 pF typical.

Environment and reliability

Operating temperature	−40 to +105°C, subject to the model-specific cooling and derating curve.
Case temperature	+100°C maximum.
Cooling and derating	PDF page 4, natural convection: 100% load through +100°C, followed by a steep decline to zero load at +105°C. The common +100°C maximum case temperature remains applicable; +105°C is not a full-load rating.
Working humidity	20–90% RH, non-condensing.
Storage temperature and humidity	−55 to +125°C; 10–95% RH, non-condensing.
Temperature coefficient	0.03%/°C over 0–85°C.
Vibration	10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each of the X, Y and Z axes.
MTBF	880,000 hours minimum, MIL-HDBK-217F at 25°C. This reliability figure is not a service-life or warranty duration.
Manufacturer warranty	3 years, as stated in the datasheet.
Design and applications	The manufacturer describes the series as low cost. Applications include telecom/datacom systems, wireless networks, industrial control, instruments, analyzers, detectors, data switches and distributed power architectures.

Safety and EMC integration

Safety standards	EAC TP TC 020/2011 approved. UL62368-1 approved; the series qualification excludes 9 V output models.
EMC emission	BS EN/EN55032 (CISPR32): conducted entry N/A; radiated Class B without additional EMC components. The separate immunity test requirements still apply.
EMC immunity	BS EN/EN61000-4-2: level 3, ±8 kV air, and level 2, ±4 kV contact; -4-3: level 2, 3 V/m; -4-4: level 1, 0.5 kV at power; -4-5: level 2, 0.5 kV line-to-line; -4-6: level 2, 3 V (e.m.f.); -4-8: level 1, 1 A/m.
Immunity input capacitor	When the module must meet BS EN/EN61000-4-4 and -4-5, an external input filter capacitor is required. The datasheet gives Power Mate's recommendation of 220 µF / 100 V for that condition.

Installation and system verification

Complete-system EMC verification	Verify EMC with the converter installed in the final equipment and connected to a representative load. Wiring, assembly and the application affect the result. Follow the model's specified EMC conditions and any required external components; the linked EMI testing guidance does not certify the finished equipment.
