UPJ1K561MHD

The UPJ1K561MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, rated at 560 µF and 80 V with ±20% tolerance. It is a low-impedance, general-purpose power capacitor designed for applications that demand robust ripple handling and long operating life.

Targeted use cases include switching power supplies and general-purpose power electronics where high ripple current capability, extended 5,000-hour life at 105°C, and wide temperature range (-55°C to 105°C) are required.

Key Features

• Capacitance & Voltage: 560 µF rated capacitance at 80 V with ±20% tolerance for bulk energy storage and decoupling.
• Low Impedance Characteristic: Designed for low impedance to support switching power supply applications and reduce ripple voltage under load.
• Ripple Current Performance: 845 mA at 120 Hz and 1.3 A at 200 kHz to accommodate both low- and high-frequency ripple conditions.
• Long Load Life: 5,000 hours at 105°C specified load life for sustained high-temperature operation.
• Leakage and Loss: Specified leakage current of 1,344 µA and tan δ of 0.08, providing predictable dissipation and leakage characteristics.
• Package & Mounting: Radial lead, can-style package with φ16 × 35.5 mm body and 7.5 mm lead spacing for through-hole PCB mounting.
• Wide Operating Temperature: Rated for −55°C to +105°C to suit a broad range of ambient conditions.
• Compliance: RoHS compliant as provided in product data.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output decoupling where low impedance and high ripple handling improve regulation and stability.
• Power Conversion Modules — Energy storage and ripple suppression in DC–DC converters and intermediate bus capacitors.
• Industrial Electronics — General-purpose power filtering and decoupling in control equipment and power distribution modules operating within −55°C to +105°C.

Unique Advantages

• Extended High-Temperature Endurance: 5,000-hour life at 105°C supports designs requiring long-term reliability under thermal stress.
• High Ripple Capability: Specified ripple currents at both 120 Hz and 200 kHz enable use across a range of switching frequencies without sacrificing performance.
• Predictable Electrical Losses: Low tan δ (0.08) and defined leakage current (1,344 µA) allow designers to size thermal and leakage budgets accurately.
• Standard Through-Hole Form Factor: φ16 × 35.5 mm radial can with 7.5 mm lead spacing integrates easily into through-hole PCBs for serviceable power modules.
• Regulatory Compliance: RoHS compliance aids selection for designs requiring restricted-substance conformance.
