The UPS2A471MHD is a miniature, low-impedance aluminum electrolytic capacitor in the Nichicon UPS series designed for switching power supplies and general-purpose power filtering. It delivers 470 µF capacitance at a 100 V rating with radial-lead packaging for through-hole mounting.

Built for wide temperature operation and long-term stability, this RoHS-compliant part is tailored for applications that require high-voltage filtering, stable ripple performance across frequency, and extended endurance at elevated temperatures.

Key Features

• Capacitance & Voltage: 470 µF rated capacitance at 100 V, suitable for high-voltage filtering and energy storage tasks.
• Low Impedance: Specified impedance of 76 mΩ, providing effective decoupling and reduced voltage ripple in power rails.
• Wide Temperature Range: Operates from −55 °C to +105 °C, supporting designs exposed to broad thermal environments.
• Endurance: Rated for 3000 hours at 105 °C under DC bias plus rated ripple current, enabling reliable long-term operation in demanding conditions.
• Ripple Current Performance: 930.1 mA at 120 Hz and 1.31 A at 10 kHz, with frequency-dependent ripple capability useful for both low- and high-frequency supply filtering.
• Package & Mounting: Radial lead, can-style package with 7.5 mm lead spacing and compact dimensions (L: 3.05 × D: 1.6 cm) for space-conscious PCB layouts.
• Polarized, ±20% Tolerance: Polarized capacitor with capacitance tolerance of −20% to +20% at 120 Hz, 20 °C.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies: Provides bulk filtering and ripple suppression on high-voltage rails in switch-mode power designs.
• General-Purpose Power Filtering: Stabilizes DC bus and smoothing tasks in a wide range of consumer and industrial electronics.
• Industrial Power Equipment: Supports high-temperature operation and extended endurance requirements in industrial power modules and controllers.
• DC Power Systems: Energy storage and decoupling in high-voltage DC power distribution and conversion subsystems.

Unique Advantages

• High-Voltage Capability: 100 V rating enables use in higher-voltage rails without stacking multiple capacitors.
• Compact, Space-Saving Form: Miniature radial-can package and short lead spacing reduce PCB footprint while maintaining required capacitance.
• Low Impedance for Better Filtering: 76 mΩ impedance improves transient response and reduces AC ripple on power rails.
• Frequency-Resilient Ripple Handling: Dedicated ripple current specifications at 120 Hz and 10 kHz support both mains-frequency and higher-frequency switching environments.
• Wide Operating Temperature & Long Life: −55 °C to +105 °C range and 3000-hour endurance at 105 °C deliver durable performance in thermally challenging applications.
• RoHS Compliance: Meets current RoHS directives for restricted substances, easing regulatory integration.
