Specified with a C4 (see typical connection diagram at right) value of 22 uF/400V. A high frequency, low impedance electrolytic capacitor should be used. For use with an AC input, C4 must be installed. 2. Load regulation is measured for an output change of 10% to 100% at nominal input line. 3. The unit will shut down when the over temperature protection is triggered. The unit will restart when the ambient operating temperature falls below 85ºC. 4. It is recommended that a fuse be used on the input of a power supply for protection. For the MPS-03 series, a 0.5A/250 VAC slow blow should be used. The diagram above illustrates a typical application connection of the MPS-03 series. The top diagram illustrates a DC/DC converter connection while the bottom diagram show the unit connected as an AC/DC power supply. Notes on these circuits are: Derating Curve 1. To maintain clearance and creepage distances (for Class I & Class II devices) the board layout should guarantee the following spacing between the L and N inputs (before the fuse): Clearance - 2 mm Creepage - 2.5 mm 2. The recommended fuse is a 0.5A/250V slow blow. 3. For EMI sensitive applications, the input filtering circuit (inside the dotted boxes of the AC circuit) may be added. The filter consists of: Cx: Capacitor C1 is 0.1 µF/275V CY: Capacitors C2 and C3 are 220 pF/2000V T1: Common mode choke, UU9.8 or ring core. Inductance is about 10 mH to 30 mH & wire diameter of 0.22 mm. 4. The MOV is required for surge protection. Recommended is a 471KD07. 5. The input storage capacitor (C4) is a low ESR electrolytic with a rating of 22 µF /400V. This capacitor must be used for operation with an AC input. 6. The output filtering capacitor (C5) is a high frequency, low resistance electrolytic capacitor. A ceramic capacitor (C6) is used to filter high frequency noise. Recommended values are given in the table at right.
