The UBY1E123MHL from Nichicon is a high-capacitance, radial-lead aluminum electrolytic capacitor in the UBY series designed for demanding power electronics. This miniature, high-reliability type offers 12,000 µF at 25 V with low equivalent series resistance and high ripple-current capability.

Targeted at automotive and other high-temperature applications, the UBY1E123MHL combines high capacitance density with extended temperature endurance and AEC-Q200 qualification to support robust power filtering and energy storage in control modules and power electronics.

Key Features

• High Capacitance — 12,000 µF (12 mF) nominal capacitance with a tolerance of −20% to +20% for bulk energy storage and smoothing.
• Rated Voltage — 25 V rated working voltage suitable for common automotive and power rail applications.
• Low Impedance / Low ESR — ESR of 18 mΩ measured at 20°C, 100 kHz, enabling improved ripple handling and reduced losses.
• High Ripple-Current Capability — Low-frequency ripple current 3.468 A at 120 Hz and high-frequency ripple current 4.08 A at 100 kHz to support heavy ripple environments.
• Loss Characteristics — tan δ (DF) of 0.36 at 20°C, 120 Hz for the specified capacitance and voltage, reflecting the capacitor’s dissipation behavior.
• Wide Temperature & Endurance — Operating range −40°C to +135°C with endurance rated for 3,000 hours at 125°C and 3,000 hours at 135°C for 25–50 V ratings.
• Robust, Through-Hole Package — Radial lead, can-style package (φ18 × 40 mm) with 7.5 mm lead spacing (±0.5 mm) for secure soldered connections or wiring.
• Quality & Compliance — AEC-Q200 rated and RoHS compliant for regulated-environment applications and supply-chain requirements.
• Practical Handling — Available in Bulk (no terminal forming) or Bag packing to suit production or prototype workflows.

Typical Applications

• Electric Power Steering (EPS) — High capacitance and ripple capability provide stable power filtering for EPS control electronics.
• Direct Injection Engine Drive — Supports engine control modules that require high transient energy delivery and reliable operation at elevated temperatures.
• Automotive Power Electronics & Control Modules — Suitable for vehicle power rails and control circuits where high temperature endurance and AEC-Q200 qualification are required.

Unique Advantages

• High Energy Density in a Compact Can — 12,000 µF in a φ18 × 40 mm package reduces board area for large bulk capacitance needs.
• Improved Thermal & Lifetime Performance — Rated to 135°C with 3,000-hour endurance, enabling longer life in high-temperature environments.
• Superior Ripple Handling — Combined low ESR (18 mΩ) and high ripple-current ratings reduce heating and improve reliability under continuous ripple load.
• Designed for Automotive Reliability — AEC-Q200 qualification aligns the part with automotive development and qualification workflows.
• RoHS Compliant — Meets regulatory materials requirements for modern production environments.
• Through-Hole Robustness — Radial lead form factor and standard 7.5 mm lead spacing simplify mounting and mechanical retention in rugged applications.
