UHV1C821MPD

The UHV1C821MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHV series. It provides 820 µF capacitance at a 16 V rating in a compact φ10 × 16 mm can, designed for general-purpose power applications.

Engineered for lower impedance at higher frequencies and elevated ripple handling, the device targets power supply smoothing, decoupling and output filtering where high ripple current, long life and a wide temperature range are required.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance with a 16 V rated voltage and tolerance of −20% to +20% for predictable bulk energy storage.
• Low Impedance / High-Frequency Performance: Specified impedance of 95 mΩ and a tangent of loss angle (tan δ) of 0.15 at 20°C/120 Hz, supporting improved performance at higher frequencies.
• High Ripple Current Capability: Low-frequency ripple current 990 mA (120 Hz) and high-frequency ripple current 1.65 A (100 kHz), enabling effective smoothing in high-ripple environments.
• Long Endurance: Rated life of 6000 hours at 105°C under DC bias plus rated ripple current, supporting extended operation in elevated-temperature applications.
• Wide Operating Temperature: −40°C to +105°C operating range to accommodate a broad set of industrial and commercial environments.
• Compact Radial Package: Radial can, φ10 × 16 mm with 5.0 mm lead spacing (±0.5 mm), available in bulk or bag packing for flexible assembly and inventory handling.
• Leakage Current: Specified leakage current of 131.2 µA (measured condition as provided), suitable for many power filtering use cases.
• RoHS Compliant: Conforms to RoHS requirements for environmental compliance.

Typical Applications

• Power Supply Output Filtering: Smooths DC outputs in switching regulators and linear supplies where high ripple current and low impedance are needed.
• DC-DC Converter Circuits: Provides bulk capacitance and transient support at converter outputs and intermediate rails.
• Industrial Control Electronics: Fits compact boards requiring robust ripple handling and long endurance in elevated-temperature enclosures.
• Consumer and Commercial Electronics: Offers space-efficient bulk storage and decoupling for audio, display and general-purpose electronic systems.

Unique Advantages

• High ripple endurance: 990 mA (120 Hz) and 1.65 A (100 kHz) ripple ratings reduce stress on upstream components and improve regulation under load variations.
• Low impedance at frequency: 95 mΩ impedance and a 0.15 tan δ contribute to improved high-frequency performance for decoupling and smoothing.
• Extended high-temperature life: 6000 hours rated life at 105°C helps ensure longevity in demanding thermal conditions.
• Compact radial form factor: φ10 × 16 mm can with 5 mm lead spacing provides high capacitance in a small footprint for space-constrained designs.
• Wide operating range: −40°C to +105°C supports deployment across varied environmental conditions without derating the core capacitance.
• Environmental compliance: RoHS-compliant construction aligns with regulatory requirements for commercial and industrial products.
