UPJ1K471MHD

The UPJ1K471MHD is a radial-lead aluminum electrolytic capacitor rated at 470 µF and 80 V, designed for low-impedance power applications. It is part of Nichicon’s UPJ series, optimized for switching power supplies and general-purpose power filtering.

Key value propositions include a wide operating temperature range from -55 °C to +105 °C, robust load-life endurance, and radial can packaging suited for through-hole power designs.

Key Features

• Capacitance and Voltage — 470 µF capacitance at a rated voltage of 80 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Low Impedance Design — Engineered for low impedance to support switching power supplies and reduce ripple voltage.
• High-Temperature Endurance — Rated for operation to +105 °C and specified load-life endurance (5000 hours at 105 °C for applicable case sizes).
• Ripple Current Capability — Handles 713 mA at 120 Hz (low frequency) and 1.15 A at 200 kHz (high frequency) for effective ripple handling in power circuits.
• Radial Lead Package — Through-hole radial, can-style package with 7.5 mm lead spacing for reliable PCB mounting and easy assembly in power modules.
• Leakage and Stability Specs — Leakage current specified as not more than 0.03CV (µA) after 1 minute at 20 °C, with defined tan δ and impedance stability characteristics across temperature.
• RoHS Compliant — Conforms to RoHS directives for environmental compliance.

Typical Applications

• Switching Power Supplies — Designed for input/output filtering and bulk energy storage in switch-mode power supplies where low impedance and high ripple handling are required.
• Industrial Power Modules — Suitable for general-purpose power conditioning in industrial electronics operating across a wide temperature range.
• DC–DC Converters — Useful for decoupling and smoothing in through-hole DC–DC converter designs.

Unique Advantages

• Proven Endurance: Specified to withstand 5000 hours of load life at +105 °C for applicable sizes, supporting long-term reliability in thermal-stressed power designs.
• Effective Ripple Management: High ripple current ratings at both low and high frequencies help reduce voltage ripple and improve regulator stability.
• Through-Hole Robustness: Radial lead, can-style packaging with 7.5 mm lead spacing simplifies assembly and provides mechanical durability for power boards.
• Wide Temperature Range: Operates from -55 °C to +105 °C, enabling use across demanding ambient conditions without derating beyond specified limits.
• Controlled Leakage Behavior: Leakage current limited to 0.03CV (µA) after initial application of rated voltage, assisting predictable power-loss budgeting in designs.
