UCYW6820MHD

The UCYW6820MHD from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can. It provides 82 µF capacitance at a 420 V rating with polarized radial leads and is designed for applications that require high ripple current and long operational life.

Targeted use cases include automotive electronics and industrial power circuitry where high ripple tolerance, robust endurance, and wide operating temperature range are required. The device is AEC-Q200 qualified, RoHS compliant, and manufactured for mass production.

Key Features

• Capacitance & Voltage — 82 µF capacitance with a rated voltage of 420 V and tolerance of -20% to +20%.
• High Ripple Current — Low-frequency ripple current 725 mA at 120 Hz and high-frequency ripple current 1.45 A at 100 kHz for demanding power applications.
• Long Endurance — Rated for 12000 hours at +105°C under DC bias plus rated ripple current (series life range noted as 10000–12000 hours in series documentation).
• Wide Temperature Range — Operating temperature from -40°C to +105°C for use across broad environmental conditions.
• Low Loss — tan δ (DF) = 0.24 measured at 20°C, 120 Hz, supporting stable ESR behavior at rated conditions.
• Leakage Current — Specified leakage current of 1477.6 µA, measured per the product’s defined conditions.
• Compact Radial Package — Dimension φ16 × 35.5 mm (L: 3.55 × D: 1.6 cm) with 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• Quality & Compliance — AEC-Q200 rated and RoHS compliant, supporting regulated manufacturing and automotive-grade processes.

Typical Applications

• Automotive Power Electronics — Energy storage and smoothing in automotive power systems where AEC-Q200 qualification and high ripple capability are required.
• Power Supplies — Bulk filtering and ripple suppression in high-voltage power supplies operating up to 420 V and temperatures up to +105°C.
• Ballasts and Industrial Power — Supports ballast and industrial power circuits that demand sustained ripple handling and long life.

Unique Advantages

• High ripple-handling capacity: Specified low- and high-frequency ripple currents (725 mA at 120 Hz, 1.45 A at 100 kHz) reduce thermal stress and improve reliability in power circuits.
• Long operational life: 12000 hours endurance at 105°C gives predictable lifetime performance for long-service applications.
• AEC-Q200 qualification: Enables use in designs requiring automotive-grade component qualification.
• Wide operating temperature: -40°C to +105°C rating supports harsh environmental operation without derating beyond specified limits.
• Compact radial form factor: φ16 × 35.5 mm can and 7.5 mm lead spacing provide a space-efficient through-hole solution for high-voltage filtering.
• Regulatory compliance: RoHS compliance supports use in regulated manufacturing and end products.
