• Rated Voltage: 50 V DC rating suitable for mid-voltage power rails and general-purpose power circuits.
• Ripple Current Capability: Low-frequency ripple current 2.1 A (120 Hz) and high-frequency ripple current 2.415 A (10 kHz), specified for thermal and ripple design considerations.
• Dissipation Factor (tanδ): tanδ = 0.12 measured at 20 °C, 120 Hz, useful for AC loss budgeting in designs.
• Leakage Current: Specified leakage current of 7050 µA for initial screening and insulation assessment.
• Temperature and Endurance: Operating range −55 °C to 105 °C with endurance specified as 2000 hours at 105 °C.
• Package and Mounting: Radial lead can, physical size φ20 × 40 mm, lead spacing 10 mm (±0.5 mm), supplied in bulk or bag packing.
• RoHS Compliance: Component is RoHS compliant as indicated in the product information.
• Product Status: End Of Life (EOL) status is indicated for lifecycle planning.

Typical Applications

• Power supply smoothing: Bulk capacitance and rated ripple current make this capacitor suitable for smoothing and energy buffering on DC power rails in general-purpose equipment.
• Decoupling and bulk storage: High capacitance supports bulk charge storage for systems that require transient energy delivery or reservoir capacitance.
• Industrial electronics: Wide operating temperature range (−55 °C to 105 °C) and 2000-hour endurance at 105 °C support use in varied environmental conditions within general-purpose industrial designs.

Unique Advantages

• High bulk capacitance: 4700 µF provides significant energy reserve for smoothing and transient suppression, reducing the need for multiple smaller capacitors.
• Defined ripple handling: Specified ripple currents at 120 Hz and 10 kHz allow designers to estimate heating and lifetime under AC stress.
• Wide temperature operation: −55 °C to 105 °C operating range supports deployment across a broad set of environments without redesigning thermal margins.
• Validated endurance: 2000 hours at 105 °C endurance rating enables reliability planning for continuous high-temperature operation.
• Clear electrical loss metric: tanδ = 0.12 (20 °C, 120 Hz) gives a quantifiable dissipation factor for PCB-level AC loss calculations.
• Packaging flexibility: Available in bulk or bag packing to accommodate production and prototyping inventory practices.
