UPS1C472MHD

The UPS1C472MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPS series. It is a radial-lead, polarized capacitor designed for power applications where compact bulk capacitance, low impedance and extended temperature capability are required.

Engineered for switching power supplies and general-purpose power filtering, this part delivers 4.7 mF at 16 V with specified ripple current performance and a wide operating temperature range for robust performance in demanding electronic power systems.

Key Features

• Capacitance & Tolerance — 4700 µF (4.7 mF) nominal with tolerance of −20% to +20%, providing bulk energy storage for power rails and smoothing.
• Rated Voltage — 16 V DC rating suitable for low-voltage power systems and converter outputs.
• Low Impedance — Specified impedance of 33 mΩ, supporting effective high-frequency decoupling and reduced ripple voltage.
• Ripple Current Capacity — 2.045 A at 120 Hz (low frequency) and 2.35 A at 10 kHz (high frequency), enabling reliable handling of converter ripple and transient currents.
• Thermal Performance & Endurance — Wide operating temperature range from −55°C to +105°C with rated life of 3000 hours at 105°C.
• Electrical Loss (tan δ) — tan δ = 0.22 measured at 20°C, 120 Hz, providing a defined dissipation factor for thermal design considerations.
• Leakage Current — Specified leakage current of 2256 µA for design accounting and initial power-up behaviour.
• Mechanical & Mounting — Radial lead, can-style package sized φ16 × 30.5 mm (3.05 × 1.6 cm) with 7.5 mm lead spacing for through-hole PCB mounting; available in bulk or bag packing.
• Compliance & Production — RoHS compliant and in mass production for predictable supply and regulatory alignment.

Typical Applications

• Switching Power Supplies — Bulk energy storage and output smoothing for DC–DC converters and SMPS designs where compact, low-impedance capacitors are required.
• Power Rail Filtering — Decoupling and ripple attenuation on 16 V and lower power rails in industrial and consumer electronics.
• Hold‑up and Energy Storage — Local energy reservoir for short-term hold-up and transient support in power-management circuits.
• General Purpose Electronics — Robust polarized capacitance for a wide range of general-purpose power applications requiring long life and wide temperature operation.

Unique Advantages

• Compact bulk capacitance: 4700 µF in a φ16 × 30.5 mm can delivers substantial energy density for space-constrained designs.
• Low ESR/impedance: 33 mΩ impedance contributes to lower ripple voltage and improved regulator stability.
• High ripple handling: Rated ripple currents of 2.045 A (120 Hz) and 2.35 A (10 kHz) support both low- and high-frequency switching environments.
• Wide temperature and long life: −55°C to +105°C operating range and 3000-hour endurance at 105°C for sustained reliability under thermal stress.
• Defined electrical characteristics: Specified tan δ and leakage current values allow predictable thermal and startup behavior in designs.
• Production-ready supply: RoHS compliance and mass-production status simplify procurement and regulatory planning.
