MIL-HDBK-217F (25J) OTHERS DIMENSION 70*48*22mm (L*W*H) 0.065Kg 120pcs/8.8Kg/0.97CUFT PACKING 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25J of ambient temperature. NOTE 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12 twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. 5. The over temperature protection (OTP) is the built-in function of the control IC (U1). The activating level described above is based on the specification provided by the IC manufacturer. 6. Touch current was measured from primary input to DC output.
