UCM1J221MNL1GS

The UCM1J221MNL1GS is a Nichicon UCM series chip‑type aluminum electrolytic capacitor designed for surface‑mount applications. It offers a 220 µF capacitance at a 63 V rating with a low‑impedance construction optimized for demanding power environments.

This part targets automotive and industrial power electronics where compact SMD packaging, high ripple handling and wide operating temperature range are required. Key value propositions include low loss (tanδ), high ripple current capability, AEC‑Q200 qualification and a durable endurance rating at elevated temperature.

Key Features

• Core Electricals — 220 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C; rated voltage 63 V.
• Low Loss / Low Impedance — tanδ up to 0.08 (measured at 20°C, 120 Hz for 63 V rating), delivering reduced AC loss in high‑frequency environments.
• Ripple Current Capability — Low‑frequency ripple current 250 mA (120 Hz) and high‑frequency ripple current 500 mA (10 kHz) to support filtering and decoupling under dynamic loads.
• Leakage Current — Specified leakage current of 138.6 µA after rated voltage application, enabling predictable standby and quiescent behavior.
• Thermal and Endurance — Operating temperature range −55°C to +105°C with endurance specified at 2000 hours at 105°C for the φD ≤ 10 mm package.
• Automotive Qualification — AEC‑Q200 rating for designs that require recognized automotive component qualification.
• Package & Mounting — Chip (radial can) SMD package, size φ10 × 10L (L: 1 cm × D: 1 cm), surface mount with embossed carrier taping for automated placement.
• Compliance — RoHS‑compliant construction.

Typical Applications

• Automotive power electronics — Energy storage and smoothing in 63 V systems where AEC‑Q200 qualification and −55°C to +105°C operation are required.
• DC–DC converters and power modules — Bulk filtering and output smoothing that benefit from 220 µF capacitance and high ripple current capability at both low and high frequencies.
• Power supply decoupling for ECUs — Local decoupling in electronic control units where compact SMD form factor and controlled leakage are important.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 250 mA (120 Hz) and 500 mA (10 kHz) reduce thermal stress in dynamic power circuits.
• Low AC loss: tanδ of 0.08 at 120 Hz (63 V) lowers dissipation and helps maintain stability over temperature.
• Automotive‑grade reliability: AEC‑Q200 qualification supports use in automotive subsystems that require qualified components.
• Wide thermal range and specified endurance: −55°C to +105°C operation with 2000 hours endurance at 105°C for the φ10 package supports long‑life designs.
• SMD chip format for automated assembly: Embossed carrier taping and compact φ10 × 10L package simplify placement in high‑volume production.
• Predictable leakage behavior: Specified leakage current (138.6 µA) enables accurate power budgeting and standby current estimates.
