UCL1A122MNL1GS

The UCL1A122MNL1GS is a surface‑mount aluminum electrolytic capacitor in Nichicon's UCL series, designed as a chip‑type, low‑impedance solution for power conditioning. It provides 1.2 mF capacitance at a 10 V rating with a compact φ10 × 10L package and embossed carrier taping for automated assembly.

Targeted for demanding electronic systems, the device combines high ripple handling, broad operating temperature range, AEC‑Q200 qualification and long endurance (2000 hours at 105°C), delivering stable filtering and decoupling performance where temperature, lifetime and reliability matter.

Key Features

• Capacitance & Voltage — 1.2 mF nominal capacitance at a rated voltage of 10 V, with tolerance of -20% to +20%.
• Low Impedance — Characteristic impedance of 80 mΩ supports low‑loss filtering and rapid charge/discharge behavior in power circuits.
• High Ripple Current — Rated ripple current of 425 mA at 120 Hz (low frequency) and 850 mA at 10 kHz (high frequency) for effective smoothing under varying switching conditions.
• Loss Tangent (tan δ) — tan δ = 0.19 measured at 20°C, 120 Hz, 10 V, enabling predictable dissipation characteristics for thermal and stability planning.
• Leakage Current — Specified leakage current of 120 µA for predictable standby and quiescent behavior.
• Robust Temperature and Endurance — Operating range from -55°C to +105°C and endurance of 2000 hours at 105°C, suitable for long‑life deployments.
• Package & Mounting — Surface‑mount, radial can SMD (φ10×10L) with recommended land size L: 1.03 × W: 1.03 cm; supplied in embossed carrier taping for SMT lines.
• Automotive Qualification & Compliance — AEC‑Q200 rating for automotive programs and RoHS compliance for environmental requirements.

Typical Applications

• Automotive Power Electronics — Bulk filtering and decoupling in automotive control units and power rails, leveraging AEC‑Q200 qualification and high ripple capability.
• DC–DC Converter Output — Output smoothing for switching converters where low impedance and high-frequency ripple handling are required.
• Embedded Power Supply Filtering — Local energy storage and transient suppression on 10 V rails for controllers and analog subsystems across temperature extremes.

Unique Advantages

• High Ripple Tolerance: Dual ripple ratings (425 mA at 120 Hz and 850 mA at 10 kHz) help manage both low‑ and high‑frequency stress on power rails.
• Predictable Thermal Behavior: Specified tan δ and leakage current at 20°C provide clear parameters for thermal and loss budgeting in design.
• Long Endurance at Elevated Temperature: 2000 hours at 105°C supports extended deployment life in thermally demanding applications.
• Automotive‑Grade Reliability: AEC‑Q200 qualification and RoHS compliance make the part suitable for regulated automotive and high‑reliability programs.
• SMT‑Ready Packaging: Embossed carrier taping and compact φ10 × 10L can format simplify high‑volume surface‑mount assembly.
