UPS1H471MHD

The UPS1H471MHD is a Nichicon UPS series aluminum electrolytic capacitor with a 470 µF capacitance and a 50 V rated voltage. It is a miniature-sized, low-impedance, radial-lead can designed for switching power supplies and general-purpose power filtering.

With a wide operating temperature range from −55°C to 105°C, defined ripple-current capability at both low and high frequencies, and a 3000-hour endurance rating at 105°C, this part is suited for compact designs that require durable bulk decoupling and stable performance in demanding thermal environments.

Key Features

• Capacitance & Voltage: 470 µF rated at 50 V for energy storage and bulk filtering in power rails.
• Low Impedance: 130 mΩ impedance to support tighter voltage regulation and reduced ripple on DC rails.
• Frequency-Hardened Ripple Handling: Rated ripple current of 781 mA at 120 Hz and 1.1 A at 10 kHz for both low- and high-frequency ripple scenarios.
• Wide Temperature Range: Operating from −55°C to 105°C for reliable performance across extreme ambient conditions.
• High Endurance: 3000 hours at 105°C when subjected to rated DC bias plus rated ripple current.
• Compact Radial Package: Radial lead, can package with dimensions approximately L × D = 2.0 cm × 1.25 cm and 5 mm lead spacing for space-constrained boards.
• Polarized, General-Purpose: Polarized aluminum electrolytic construction intended for general-purpose power applications.
• Capacitance Tolerance: ±20% at 120 Hz, 20°C for predictable design margins.
• Low Leakage Characteristic: Series specification: after 1 minute’s application of rated voltage at 20°C, leakage current is not more than 0.03 × C × V (µA).
• RoHS Compliant: Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies: Bulk filtering and smoothing for switching regulators where compact size and low impedance reduce output ripple.
• Power Filtering and Decoupling: Bulk energy storage and decoupling on DC rails for converters and power distribution circuits.
• High-Frequency Ripple Management: Handling of both low- and high-frequency ripple components thanks to specified ripple current performance at 120 Hz and 10 kHz.
• General-Purpose Electronics: Suitable for a wide range of general-purpose power applications requiring polarized electrolytic capacitors with defined lifetime and temperature performance.

Unique Advantages

• Compact footprint: Small radial-can dimensions and 5 mm lead spacing enable installation in space-constrained layouts.
• Measured low impedance: 130 mΩ impedance helps improve transient response and reduce voltage ripple on power rails.
• Broad ripple capability: Explicit ripple current ratings at both 120 Hz and 10 kHz support mixed-frequency power environments.
• Extended high-temperature endurance: 3000 hours at 105°C gives designers a clear high-temperature lifecycle expectation.
• Wide operating temperature: −55°C to 105°C range supports deployment across harsh and variable thermal conditions.
• Regulatory compliance: RoHS compliance supports use in markets requiring environmental directive adherence.
