UBY1K821MHL

The UBY1K821MHL is an aluminum electrolytic capacitor in a radial‑lead can, offering 820 µF nominal capacitance at a rated voltage of 80 V. It is part of Nichicon’s UBY series, which emphasizes high ripple current and high‑temperature endurance for demanding control circuits.

Engineered for automotive control applications, this radial‑lead unit combines high ripple handling (1.83 A at 120 Hz, 3.05 A at 100 kHz), low ESR (34 mΩ at 20°C/100 kHz) and a wide operating temperature range (‑40°C to 135°C), with AEC‑Q200 qualification and RoHS compliance.

Key Features

• Capacitance and Tolerance — 820 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C for predictable energy storage and filtering performance.
• Rated Voltage — 80 V DC rating suited for higher‑voltage control and power domains.
• High Ripple Current — Low‑frequency ripple current 1.83 A (120 Hz) and high‑frequency ripple current 3.05 A (100 kHz) to support heavy ripple loads in power circuits.
• Low ESR — 34 mΩ equivalent series resistance measured at 20°C/100 kHz to reduce heat generation and improve filtering efficiency.
• High‑Temperature Endurance — Rated for operation from ‑40°C to 135°C with an endurance of 2000 hours at 135°C, designed for elevated‑temperature environments.
• Mechanical / Mounting — Radial lead, can package with φ16 × 30.5 mm body and 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing for assembly flexibility.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant for regulated applications and supply‑chain requirements.

Typical Applications

• Automotive control modules — Energy storage and smoothing in control circuits for systems such as electric power steering.
• Engine management — Filtering and decoupling in direct injection engine drive and related high‑stress power electronics.
• Power supply filtering — Bulk and ripple filtering in automotive power domains where high ripple current and elevated temperature capability are required.

Unique Advantages

• High ripple handling: Specified ripple current of 1.83 A (120 Hz) and 3.05 A (100 kHz) enables sustained performance under heavy AC stress.
• Low thermal losses: 34 mΩ ESR at 20°C/100 kHz minimizes I²R losses and helps control temperature rise in tight enclosures.
• Wide temperature capability: Operating range from ‑40°C to 135°C with 2000 h endurance at 135°C supports high‑temperature applications.
• Automotive qualification: AEC‑Q200 rating provides a documented reliability baseline for automotive electronic designs.
• Compact radial form factor: φ16 × 30.5 mm can with 7.5 mm lead spacing balances capacitance and board‑level footprint for through‑hole assemblies.
• Production ready: Mass production status and packaging options (bulk / bag) simplify procurement and assembly planning.
