UPS1A470MDD

The UPS1A470MDD is a miniature, low-impedance aluminum electrolytic capacitor from Nichicon’s UPS series, designed for switching power supplies and general-purpose applications. It delivers 47 µF capacitance at a 10 V rating in a compact radial-can package suited for through-hole PCB mounting.

Built for a wide operating range, the UPS1A470MDD supports −55 °C to 105 °C operation and is RoHS compliant, providing a balance of small size, ripple handling and elevated-temperature endurance for compact power designs.

Key Features

• Capacitance & Voltage: 47 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance (at 120 Hz, 20 °C), suitable for decoupling and energy-storage roles in low-voltage power rails.
• Low Impedance & Ripple Handling: Low-impedance construction with specified ripple current performance of 27.2 mA at 120 Hz and 160 mA at 10 kHz; frequency coefficients from the UPS series apply across the 22–47 µF range to characterize ripple capability.
• Wide Temperature Range: Rated for −55 °C to +105 °C operation, enabling use in environments with broad thermal variation.
• Elevated-Temperature Endurance: Designed for long-term operation at high temperature with a lifetime rating of 2000 hours at 105 °C for this case size.
• Package & Mounting: Radial lead, can-style package with 2 mm lead spacing and compact dimensions (L: 1.1 cm × D: 0.5 cm), facilitating dense through-hole PCB layouts.
• Electrical Characteristics: Polarized device with leakage current specified by the UPS series (≤ 0.03 × C × V μA after 1 minute at 20 °C) and a maximum tan δ of 0.20 at 10 V (measured at 120 Hz, 20 °C).
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), meeting common regulatory requirements for lead-free assemblies.

Typical Applications

• Switching Power Supplies: Bulk and decoupling capacitor for low-voltage switching regulators where low impedance and compact size are required.
• General-Purpose Electronics: Through-hole power filtering and energy storage in compact consumer and industrial boards classified as general-purpose use.
• Through-Hole PCB Assemblies: Radial-lead format for straightforward insertion and soldering in legacy or mixed-technology boards where a small can-style electrolytic is needed.

Unique Advantages

• Space-Efficient Design: Miniature L: 1.1 × D: 0.5 cm footprint minimizes board area for power filtering components.
• Demonstrated Ripple Capability: Specified ripple current values at 120 Hz and 10 kHz support assessment of AC stress in switching applications.
• High-Temperature Durability: 2000-hour lifetime at 105 °C provides predictable performance in elevated-temperature environments.
• Wide Operating Temperature: Rated from −55 °C to +105 °C for use across a broad environmental range.
• Regulatory Compliance: RoHS conformity supports lead-free product designs and regulatory requirements.
• Through-Hole Friendly: Radial lead and 2 mm lead spacing simplify assembly in through-hole manufacturing flows.
