UHV1A821MPD

The UHV1A821MPD is a radial-lead aluminum electrolytic capacitor designed for general-purpose electronic applications that require high ripple handling and low impedance at higher frequencies. It delivers 820 µF at 10 V with a compact φ10 × 12.5 mm can and radial mounting for through-hole assemblies.

Key value propositions include high ripple-current capability across low and high frequencies, long endurance (6000 hours at 105°C), and low dissipation factor for stable performance in power-filtering and decoupling roles within industrial and consumer electronic designs.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 10 V with ±20% tolerance, suitable for bulk smoothing and decoupling in low-voltage circuits.
• Low Dissipation Factor — tanδ of 0.18 at 20°C and 120 Hz, supporting efficient charge/discharge behavior and reduced AC losses.
• High Ripple Current — 750 mA at 120 Hz (low frequency) and 1.25 A at 100 kHz (high frequency), enabling robust filtering under AC ripple stress.
• Low Impedance — Impedance specified at 133 mΩ, optimized for lower voltage drop and improved filtering performance at operating frequencies.
• Reliability & Endurance — Rated for 6000 hours at 105°C; after endurance testing, capacitance remains within ±30% (for 10 V parts), with leakage current and tanδ within specified limits.
• Package & Mounting — Radial lead can (φ10 × 12.5 mm) with 5.0 mm lead spacing (±0.5 mm), supplied in bulk (no terminal forming) or bag packing for through-hole assembly.
• Operating Range & Compliance — Operates from −40°C to +105°C and is RoHS compliant.

Typical Applications

• Power supply filtering — Bulk smoothing and output filtering where high ripple current capability (750 mA at 120 Hz; 1.25 A at 100 kHz) and low impedance improve voltage stability.
• DC/DC converter decoupling — Local energy storage and ripple suppression in converters, leveraging the unit’s low impedance and compact radial can.
• Industrial and consumer electronics — General-purpose decoupling and bulk capacitance in control boards and power modules that require long endurance at elevated temperatures.

Unique Advantages

• High ripple-handling capability: Rated ripple currents of 750 mA (120 Hz) and 1.25 A (100 kHz) support demanding filtering environments and reduce thermal stress on the capacitor.
• Low impedance at frequency: 133 mΩ impedance helps maintain low voltage drop and effective high-frequency performance in power circuits.
• Compact radial form factor: φ10 × 12.5 mm can and 5.0 mm lead spacing deliver substantial capacitance in a small through-hole footprint for space-constrained designs.
• Long endurance at elevated temperature: 6000-hour rating at 105°C with defined post-test limits (capacitance within ±30% for 10 V parts) provides predictable long-term behavior.
• Controlled leakage and dissipation: Specified leakage current (82 µA) and tanδ (0.18 at 20°C/120 Hz) support reliable, low-loss operation in power circuits.
• RoHS compliant and production-ready: Part is mass production status and RoHS compliant for regulatory alignment.
