UPS1A472MHD

The UPS1A472MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPS series, designed for radial-lead mounting in power circuits. It provides 4700 µF capacitance at a 10 V rating with low impedance and high ripple-current capability suited to switching power supplies and general-purpose power filtering.

Key value propositions include a compact φ16 × 25 mm can, wide operating temperature range from −55 °C to 105 °C, and endurance rated for 3000 hours at 105 °C—making it suitable for designs that demand sustained thermal and electrical performance in a small footprint.

Key Features

• Capacitance & Voltage: 4700 µF (4.7 mF) rated at 10 V for bulk energy storage and smoothing in low-voltage power rails.
• Low Impedance: Specified impedance of 38 mΩ (20 °C / 100 kHz) to minimize AC voltage ripple and improve transient response.
• High Ripple Current Capability: Low-frequency ripple current 1.653 A at 120 Hz and high-frequency ripple current 1.9 A at 10 kHz to handle switching supply ripple across a broad frequency range.
• Thermal Endurance: Rated for 3000 hours at 105 °C under DC bias plus rated ripple current, supporting long-term operation in elevated-temperature environments.
• Wide Temperature Range: Operates from −55 °C to 105 °C, enabling use in demanding thermal conditions.
• Dielectric Loss (tan δ): Specified dissipation factor (tan δ) of 0.26 at 20 °C, 120 Hz for this part number.
• Leakage Current: Leakage current listed as 1410 µA after rated voltage application, allowing designers to budget for standby currents.
• Compact Radial Lead Package: φ16 × 25 mm can with 7.5 mm lead spacing (±0.5 mm); available in bulk or bag packing for through-hole assembly.
• RoHS Compliant: Conforms to RoHS directive, suitable for environments requiring RoHS-compliant components.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output filtering where high ripple-current capability and low impedance are required.
• General-Purpose Power Circuits: Energy storage and decoupling in low-voltage power rails for electronic equipment.
• Power Conditioning Modules: Filtering and ripple attenuation across a range of frequencies thanks to high-frequency ripple current rating.

Unique Advantages

• High ripple-current headroom: 1.653 A at 120 Hz and 1.9 A at 10 kHz support robust performance in switching environments without overspecifying component count.
• Small footprint, large capacitance: 4700 µF in a φ16 × 25 mm can reduces PCB real estate compared with larger case sizes while maintaining bulk capacitance.
• Wide operating temperature and long life: −55 °C to 105 °C rating with 3000 hours endurance at 105 °C provides predictable behavior in thermally stressed systems.
• Measurable low impedance: 38 mΩ at 20 °C (100 kHz) offers a verifiable metric for designers optimizing ESR/impedance in power stages.
• Through-hole reliability and ease of assembly: Radial lead configuration and standard 7.5 mm lead spacing simplify placement and soldering for manual or automated through-hole processes.
• Standards-conscious selection: RoHS compliance supports deployment in regulated product lines and markets that require restricted-substance adherence.
