Cornell Dubilier Aluminum Polymer 277XMPL004MG19R

The 277XMPL004MG19R is a 4 VDC, 270 µF aluminum polymer chip capacitor with a maximum ESR of 0.3684 Ω and a rated ripple current of 108 mA at 105°C. It has a case size of 7.3 mm × 4.3 mm × 2.7 mm and complies with the EIA G19 case code. The operating temperature range is -55°C to +105°C, with a leakage current of 7 µA at 25°C after 2 minutes. It meets RoHS compliance and uses halogen-free epoxy, with a dissipation factor below 0.06 at 120 Hz and 20°C. Load life guarantees a capacitance change of less than 20% and dissipation factor under 300% of maximum after 2000 hours at 105°C with rated voltage applied. Moisture resistance testing follows 500 hours at 60°C and 90% relative humidity with no voltage applied.
