UCM2A131MNJ1MS

The UCM2A131MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor in a compact surface-mount can. It provides 130 µF capacitance at a 100 V rating with a wide operating temperature range of −55 °C to +105 °C, and is offered in an embossed carrier taping format for automated assembly.

Engineered for demanding environments, this AEC-Q200 qualified device and RoHS‑compliant construction deliver high ripple handling and long-term endurance (5000 hours at 105 °C), making it suitable for robust power-electronics applications in automotive and related markets.

Key Features

• Electrical performance — 130 µF rated capacitance with ±20% tolerance (measured at 120 Hz, 20 °C); low impedance (0.18 Ω max. at 20 °C / 100 kHz) and low dissipation (tan δ 0.07 at 100 V, 120 Hz) for effective noise suppression and energy storage.
• High voltage rating — 100 V rated voltage for higher-voltage power rails and bulk energy filtering.
• Ripple capability — Rated ripple current up to 1.05 A at 105 °C / 100 kHz and 525 mA at 120 Hz, enabling sustained AC load handling in switching power stages.
• Reliability and lifetime — AEC-Q200 qualified with 5000 hours endurance at 105 °C; meets leakage and stability requirements after long-term high-temperature voltage application.
• Wide temperature range — −55 °C to +105 °C operating range for extended-environment use.
• Compact SMD package — Case size φ12.5 × 13.5 mm (L: 1.35 × D: 1.25 cm) in a radial can SMD format; supplied in embossed carrier taping for automatic placement.
• Leakage current — 130 µA maximum after 2 minutes at 20 °C under rated voltage, supporting predictable bias performance at power-up.
• Compliance — RoHS compliant and produced for mass-production availability.

Typical Applications

• Automotive power electronics — Bulk filtering and decoupling on higher-voltage rails, leveraging the 100 V rating, low impedance and 1.05 A ripple capability for stable DC-DC converter operation.
• Power-supply smoothing — Energy storage and ripple attenuation in switching regulators and power stages where high ripple current and low ESR are required.
• Embedded control modules — SMD-ready format and embossed carrier taping enable automated assembly of compact control units that require durable capacitors rated for −55 °C to +105 °C and long endurance.

Unique Advantages

• High-voltage, high-capacitance combination: 100 V rating with 130 µF capacitance provides substantial energy storage in a compact SMD can for higher-voltage designs.
• Low impedance and controlled losses: 0.18 Ω max impedance and tan δ of 0.07 reduce ripple voltage and dissipative heating, improving power-stage stability.
• Designed for automotive-grade reliability: AEC-Q200 qualification and 5000 hours endurance at 105 °C address long-term reliability demands in harsh environments.
• Automated assembly ready: Embossed carrier taping supports placement by automatic mounting equipment, simplifying PCB integration and manufacturing throughput.
• Predictable leakage behavior: Specified leakage current (130 µA after 2 minutes at 20 °C) supports reliable bias management during power-up and in standby conditions.
• Regulatory compliance: RoHS‑compliant construction aligns with environmental requirements for commercial production.
