UHV1E821MPD

The UHV1E821MPD is an aluminum electrolytic capacitor in a radial-lead can from Nichicon’s UHV series. It provides 820 μF capacitance at a 25 V rating in a compact φ10 × 20 mm can with 5 mm lead spacing, designed for general-purpose power applications that require high ripple handling and low impedance.

Built for sustained operation across a wide ambient range (−40°C to 105°C) and rated for 6000 hours at 105°C, this component is intended for designs that need durable bulk capacitance, elevated ripple-current capability, and RoHS compliance.

Key Features

• Capacitance and Voltage: 820 μF nominal capacitance with a 25 V rated voltage and ±20% tolerance, providing substantial energy storage for decoupling and bulk filtering.
• Low Impedance: Rated impedance of 57 mΩ that supports lower AC voltage drop and improved filtering performance in power rails.
• High Ripple Current Capability: Low-frequency ripple current 1.296 A (120 Hz) and high-frequency ripple current 2.16 A (100 kHz), enabling reliable handling of both mains and switching ripple profiles.
• Loss and Leakage: Tan δ of 0.13 (measured at 20°C, 120 Hz) and leakage current specified as 205 μA, offering predictable dissipation and leakage characteristics for thermal and power budgets.
• Robust Endurance and Temperature Range: Rated for 6000 hours at 105°C and operating from −40°C to +105°C for long-term stability in elevated-temperature environments.
• Compact Radial Package: φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting—available in bulk or bag packing for straightforward through-hole assembly.
• Regulatory Compliance: RoHS compliant as specified in the product data.

Typical Applications

• General-purpose power supplies: Bulk decoupling and smoothing in 25 V rails where 820 μF capacitance and high ripple capability reduce output ripple and stabilize regulators.
• Switching converters and DC–DC stages: Handles switching ripple up to 100 kHz with a specified 2.16 A high-frequency ripple rating for improved transient response and filtering.
• Industrial and control electronics: Durable operation to 105°C and 6000-hour endurance make it suitable for power conditioning in control modules and instrumentation.

Unique Advantages

• High ripple tolerance: Distinct LF and HF ripple current ratings (1.296 A @120 Hz; 2.16 A @100 kHz) reduce the need for parallel parts to meet ripple requirements.
• Compact energy density: 820 μF in a φ10 × 20 mm package saves PCB space while delivering substantial bulk capacitance.
• Predictable thermal and electrical behavior: Specified tan δ, impedance, and leakage figures allow accurate thermal and power-loss planning.
• Long endurance at elevated temperature: 6000-hour rating at 105°C supports reliable long-term deployment in thermally demanding systems.
• Through-hole simplicity: Radial-lead can and standard 5 mm lead spacing simplify prototyping, assembly, and replacement.
