UHE1V561MPD

The UHE1V561MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UHE series designed for high-reliability general-purpose power applications. It provides 560 µF capacitance at a 35 V rating in a compact φ10 × 25 mm can with 5 mm lead spacing.

Built for low impedance and extended endurance, this part supports wide operating conditions (–40 °C to +105 °C) and long life at elevated temperature (7000 hours at 105 °C), making it suitable for bulk energy storage, filtering and smoothing in equipment where steady ripple handling and durability matter.

Key Features

• Electrical characteristics — 560 µF nominal capacitance with ±20% tolerance and rated voltage of 35 V. Specified impedance is 170 mΩ and tan δ is 0.12 (measured at 20 °C, 120 Hz).
• Ripple current handling — Low-frequency ripple current of 1.2375 A at 120 Hz and high-frequency ripple current of 1.65 A at 10 kHz, enabling effective smoothing under AC ripple conditions.
• Leakage current — Specified leakage current of 196 µA after rated voltage application, supporting predictable standby and quiescent behavior.
• High-temperature endurance — Rated life of 7000 hours at 105 °C when operated under specified conditions, reflecting the UHE series’ focus on long-term reliability.
• Compact radial-lead package — φ10 × 25 mm can with 5 mm lead spacing (lead spacing tolerance ±0.5 mm) in radial, can-style package for through-hole mounting; available in bulk (no terminal forming) or bag packing.
• Wide operating temperature — Specified for –40 °C to +105 °C operation to accommodate a broad range of environmental conditions.
• RoHS compliant — Conforms to RoHS requirements as indicated in the product data.

Typical Applications

• Power supply filtering and bulk smoothing — 560 µF at 35 V combined with low impedance and high ripple current capability makes it suitable for DC bus smoothing and reservoir capacitance in power supplies.
• DC-DC converter output filtering — Compact φ10 × 25 mm package and strong high-frequency ripple rating help stabilize converter outputs and reduce output voltage ripple.
• General-purpose electronics — Durable operation from –40 °C to +105 °C and 7000-hour endurance supports reliable performance in industrial and consumer equipment requiring dependable decoupling and energy storage.

Unique Advantages

• Proven series reliability — Part of Nichicon’s UHE series, which emphasizes low impedance and extended life under elevated-temperature operation.
• High ripple resilience — Rated ripple currents at both 120 Hz and 10 kHz provide versatility across low- and high-frequency power environments.
• Compact footprint — φ10 × 25 mm can delivers substantial capacitance in a small through-hole package to save board space while maintaining radial-lead mounting simplicity.
• Predictable electrical behavior — Specified impedance, tan δ and leakage current values allow engineers to model performance and heat dissipation precisely.
• Wide temperature range — –40 °C to +105 °C operating window supports deployment across varied thermal environments.
• RoHS compliant — Environmentally conscious manufacturing and compliance for designs requiring RoHS status.
