UCM2A241MNJ1MS

The UCM2A241MNJ1MS is a surface‑mount aluminum electrolytic capacitor in Nichicon’s UCM chip family, designed for low‑impedance power applications. It combines a 240 µF capacitance with a 100 V rated voltage and a compact radial can SMD package intended for automated assembly.

Targeted for automotive and high‑reliability electronics, this part delivers specified endurance and wide operating temperature range to support demanding power filtering and smoothing applications.

Key Features

• Capacitance & Voltage — 240 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• Low Loss / Low Impedance — tanδ (DF) specified at 0.07 (measurement condition: 20°C, 120 Hz, 100 V) for reduced power dissipation in AC conditions.
• Ripple Current Capability — Low‑frequency ripple current 750 mA (120 Hz) and high‑frequency ripple current 1.5 A (10 kHz) to support bulk and decoupling duties across frequency ranges.
• Leakage Current — Leakage current specified at 240 µA after rated voltage application (measurement condition per product data).
• Temperature & Endurance — Operating temperature range −55°C to +105°C with endurance rated 5000 hours at 105°C.
• Automotive Grade & Reliability — AEC‑Q200 qualified per product specifications for designs requiring automotive qualification.
• Package & Assembly — Surface‑mount radial can (φ16 × 16.5 mm length), supplied in embossed carrier taping for automated placement; recommended land size L 1.63 × W 1.63 cm.
• RoHS Compliance — Component is RoHS compliant as specified in the product data.

Typical Applications

• Automotive power electronics — Suitable for filtering and smoothing in automotive power subsystems where AEC‑Q200 qualification and a −55°C to +105°C operating range are required.
• Power supply bulk decoupling — 240 µF at 100 V with high ripple current capability supports bulk energy storage and ripple suppression in DC‑DC converters and power rails.
• High‑temperature environments — Endurance of 5000 hours at 105°C makes this capacitor appropriate for electronics exposed to sustained elevated temperatures.
• Surface‑mount manufacturing — Embossed carrier taping and SMD radial can package enable automated pick‑and‑place assembly for volume production.

Unique Advantages

• High voltage capability: 100 V rating provides margin for higher‑voltage power rails while maintaining 240 µF capacitance.
• Wide temperature endurance: Rated for −55°C to +105°C and 5000 h at 105°C, supporting long‑life operation in thermally demanding systems.
• Dual‑band ripple handling: Specified ripple currents at both 120 Hz and 10 kHz enable effective performance across low and high frequency power disturbances.
• Automotive qualification: AEC‑Q200 rating aligns the part with automotive design and validation requirements.
• Manufacturing ready: Embossed carrier taping and recommended land size optimize the part for automated surface‑mount assembly processes.
• Predictable leakage and loss: Specified leakage current and low tanδ at 120 Hz facilitate predictable thermal and power performance in system designs.
