UBX1J681MHL

The UBX1J681MHL is a radial-lead miniature aluminum electrolytic capacitor from Nichicon's UBX series designed for high-reliability, high-temperature applications. It provides 680 µF capacitance at a 63 V rating in a compact φ16 × 35.5 mm can with 7.5 mm lead spacing.

Engineered for demanding environments, this capacitor delivers long-life performance (2,000 hours at 150°C) and supports both low- and high-frequency ripple current handling, making it suitable for robust power filtering and energy buffering in harsh-temperature systems.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance, offering stable bulk capacitance for DC bus and smoothing applications.
• High Temperature Endurance: Rated operating range –55°C to +150°C with an endurance specification of 2,000 hours at 150°C, supporting extended operation in elevated-temperature environments.
• Ripple Current Performance: Low-frequency ripple current 1.0184 A at 120 Hz and high-frequency ripple current 1.52 A at 100 kHz, enabling effective ripple handling across a broad frequency range.
• Leakage & Dissipation: Specified leakage current of 1,285.2 µA and a dissipation factor (tan δ) of 0.1 measured at 20°C, 120 Hz, providing predictable loss characteristics for thermal and design calculations.
• Reliability Standard: AEC-Q200 rated per product specifications and compliant with RoHS, indicating suitability for rigorous qualification workflows.
• Mechanical & Packaging: Radial lead can package, dimension φ16 × 35.5 mm (L × D: 3.55 × 1.6 cm), 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for flexible assembly options.

Typical Applications

• Automotive electronics: Power supply filtering and energy buffering in vehicle control modules where extended high-temperature endurance and AEC-Q200 compatibility are required.
• High-temperature power supplies: Bulk energy storage and smoothing for DC-DC converters and power rails operating in elevated ambient temperatures.
• Industrial control systems: Robust ripple suppression and energy decoupling for controllers and inverters exposed to heavy-duty duty cycles and thermal stress.

Unique Advantages

• High-temperature durability: 2,000 hours rated endurance at 150°C reduces replacement frequency and supports extended life in hot environments.
• Wide operating temperature range: –55°C to +150°C enables deployment across extreme thermal conditions without design derating.
• Broad ripple handling: Specified ripple currents at both 120 Hz and 100 kHz give designers predictable performance for low- and high-frequency filtering tasks.
• Automotive-grade reliability: AEC-Q200 rating aligns the component with automotive qualification workflows and reliability expectations.
• Compact radial package: φ16 × 35.5 mm can with 7.5 mm lead spacing provides a small footprint for through-hole assemblies while retaining high capacitance.
• Regulatory compliance: RoHS-compliant construction supports environmental requirements for regulated markets.
