UPJ1A472MHD

The UPJ1A472MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series. It is a radial-lead, polarized can designed for general-purpose power applications and is specifically noted for low impedance performance suited to switching power supplies.

With a rated voltage of 10 V, 4700 µF capacitance, and an operating temperature range of −55 °C to +105 °C, this part targets applications requiring compact bulk capacitance, robust ripple handling, and extended life under elevated temperature load conditions.

Key Features

• Electrical Performance: 4700 µF nominal capacitance at 10 V with ±20% tolerance and a measured tan δ of 0.25 (20 °C, 120 Hz), providing substantial bulk energy storage for power filtering and decoupling.
• Ripple Current Handling: Low-frequency ripple current of 1.953 A (120 Hz) and high-frequency ripple current of 2.17 A (200 kHz), enabling effective smoothing in both line-frequency and switching environments.
• Reliability & Endurance: Rated for 5000 hours life at 105 °C under load, reflecting a design emphasis on sustained performance in high-temperature operating conditions.
• Wide Temperature Range: Specified to operate from −55 °C to +105 °C, suitable for a broad array of ambient conditions.
• Compact Radial Package: 16 mm diameter × 30.5 mm length (φ16 × 30.5L) with 7.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through‑hole assembly.
• Environmental Compliance: RoHS compliant, meeting current lead-free directive requirements.
• Low Impedance Design: UPJ series characteristic of low impedance optimized for switching power supply applications, improving voltage stability under dynamic loads.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output filtering where low impedance and sustained ripple handling improve regulation and reduce output ripple.
• Power Conversion Modules: Bulk energy storage and decoupling in DC–DC converters and power regulator modules requiring compact, high-capacitance solutions.
• General Purpose Power Filtering: Through-hole designs needing reliable bulk capacitance for smoothing and transient suppression.

Unique Advantages

• High Capacitance in a Compact Can: 4700 µF in a φ16 × 30.5 mm package provides significant bulk capacitance while minimizing board area for through‑hole designs.
• Strong Ripple Endurance: Rated ripple currents at both low and high frequencies support mixed-frequency power systems and switching environments.
• Extended High-Temperature Life: 5000 hours at 105 °C offers predictable long-term behavior for designs that operate at elevated temperatures.
• Wide Operating Temperature Range: −55 °C to +105 °C capability allows deployment across diverse ambient conditions without changing capacitor selection.
• RoHS Compliance: Meets current environmental requirements for lead‑free assemblies and regulatory conformity.
• Radial-Lead Convenience: Standard lead spacing and radial mounting simplify through‑hole assembly and replacement in existing designs.
