UCM1E242MNJ1MS

The UCM1E242MNJ1MS is a chip‑type, low‑impedance aluminum electrolytic capacitor designed for surface‑mount assembly. It delivers 2400 µF capacitance at a 25 V rating in a compact φ12.5 × 21 mm case and is supplied on embossed carrier tape for automated placement.

Engineered for demanding temperature and ripple environments, this part is AEC‑Q200 rated and specified for operation from −55°C to +105°C with 5000 hours endurance at 105°C, making it suitable for automotive and other high‑reliability power applications.

Key Features

• Capacitance & Voltage — 2400 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance for bulk energy storage and decoupling.
• Low Impedance — Specified impedance of 46 mΩ and tanδ of 0.16 (measured at 20°C, 120 Hz) to reduce ripple and improve transient response.
• High Ripple Current Handling — Low‑frequency ripple current of 1.04 A (120 Hz) and high‑frequency ripple current of 2.08 A (10 kHz) for high‑duty power circuits.
• Reliability & Endurance — Rated for 5000 hours at 105°C; leakage current specified at 600 µA, supporting long service life in elevated temperature environments.
• Automotive Qualification — AEC‑Q200 rating for designs that require recognized automotive component standards.
• Surface Mount Packaging — Chip/can SMD package (φ12.5 × 21 mm) with embossed carrier taping for automated SMT placement.
• Wide Temperature Range — Operating from −55°C to +105°C to cover harsh environmental conditions.
• Regulatory — RoHS compliant.

Typical Applications

• Automotive power systems — AEC‑Q200 qualification, wide operating temperature range, and long endurance make this capacitor suitable for power filtering and energy buffering in vehicle electronics.
• High‑ripple DC‑DC converters — High ripple current ratings at both low and high frequencies support smoothing and stability in switching regulator outputs.
• Surface‑mount production — Chip‑type SMD can with embossed carrier taping enables automated placement for high‑volume assembly lines.

Unique Advantages

• High capacitance in a compact SMD can: 2400 µF in a φ12.5 × 21 mm package provides substantial bulk storage while preserving board area.
• Improved ripple performance: Dual ripple‑current specifications (1.04 A at 120 Hz and 2.08 A at 10 kHz) allow designers to address both mains‑frequency and switching noise with a single part.
• Designed for elevated temperatures: 5000‑hour endurance at 105°C and operation down to −55°C support long‑term stability in harsh thermal environments.
• Automotive readiness: AEC‑Q200 rating and RoHS compliance reduce qualification overhead for vehicle electronics designs.
• Manufacturing friendly: Embossed carrier taping and chip‑type form factor simplify automated SMT handling and placement.
