UBY2A511MHL

The UBY2A511MHL is a radial-lead aluminum electrolytic capacitor in Nichicon’s UBY series, optimized for high-temperature and high-ripple environments. This miniature, high-reliability can-type capacitor delivers 510 µF at 100 V with a compact φ18 × 25 mm form factor and 7.5 mm lead spacing.

Designed for demanding automotive control circuitry and other high-temperature applications, the component combines elevated ripple-current capability, low ESR at high frequency, and AEC‑Q200 qualification to support robust power delivery in constrained spaces.

Key Features

• Capacitance & Voltage — 510 µF nominal capacitance rated at 100 V with a capacitance tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High-Temperature Operation — Rated operating temperature range from −40°C to +135°C to support elevated-temperature system environments; endurance specified for 2000 hours at 135°C.
• High Ripple-Current Capability — Low-frequency ripple current of 1.405 A at 120 Hz and high-frequency ripple current of 2.81 A at 100 kHz, enabling effective smoothing under heavy dynamic loads.
• Low High-Frequency ESR — ESR of 35 mΩ measured at 20°C and 100 kHz to reduce dissipation and improve high-frequency performance.
• Loss Tangent (tan δ) — tan δ of 0.08 measured at 20°C, 120 Hz, for the 100 V rating, supporting predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 1530 µA for the part, measured after application of rated voltage.
• Package & Mounting — Radial lead can package (φ18 × 25 mm) with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Automotive-Grade Reliability — AEC‑Q200 qualified and RoHS compliant, supporting automotive and similarly stringent system requirements.

Typical Applications

• Automotive control circuits — Suited for control circuitry in vehicles where elevated temperature and high ripple currents are present.
• Electric power steering systems — Targets power filtering and energy buffering needs in electric power steering modules.
• Direct injection engine drive — Applicable to engine control modules and related drive circuits requiring high-temperature endurance and ripple tolerance.

Unique Advantages

• High ripple-current handling: 1.405 A (120 Hz) and 2.81 A (100 kHz) ratings reduce the need for parallel capacitors in high‑dynamic circuits.
• Low ESR at high frequency: 35 mΩ (20°C, 100 kHz) lowers power loss and improves stability in high-frequency switching environments.
• High-temperature endurance: Rated for operation to 135°C with a 2000-hour endurance specification at 135°C, supporting long-term use in hot locations.
• Automotive qualification: AEC‑Q200 qualification and RoHS compliance align the component with automotive reliability and environmental standards.
• Compact radial-lead form: φ18 × 25 mm can with 7.5 mm lead spacing provides a space-efficient solution for through-hole mounting and serviceability.
