UCZ1V471MNJ1MS

The UCZ1V471MNJ1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly where high reliability and elevated operating temperature are required. It provides 470 µF capacitance at a 35 V rating with a low-temperature ESR specification and is qualified for demanding environments up to +125°C.

Targeted at applications that require robust power filtering and stable performance across a wide temperature range, this part combines high ripple-handling capability, AEC‑Q200 qualification, and embossed carrier taping for automated placement.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 35 V and a capacitance tolerance of ±20% (120 Hz, 20°C).
• Low‑temperature ESR specification — ESR specified as 60 mΩ measured at 20°C and 100 kHz, with ESR characterization maintained after a −40°C test.
• High ripple current capability — Low‑frequency ripple current 850 mA at 120 Hz and high‑frequency ripple current 1.7 A at 100 kHz for improved filtering performance under dynamic loads.
• Wide operating temperature — Rated for −40°C to +125°C operation, suitable for elevated‑temperature environments.
• Long endurance at high temperature — Endurance rating of 3000 hours at 125°C.
• Leakage and dissipation — Specified leakage current of 164.5 µA and tan δ of 0.16 measured at 20°C, 120 Hz.
• Surface‑mount CAN package — φ12.5 × 13.5 mm can-style SMD package with surface-mount land size L: 1.28 × W: 1.28 cm; supplied in embossed carrier tape for automated mounting.
• Standards and compliance — AEC‑Q200 qualified and RoHS compliant.

Typical Applications

• Automotive systems — AEC‑Q200 qualification and +125°C operation make this capacitor suitable for automotive electronic modules that require stable filtering in high-temperature environments.
• High‑temperature electronics — Designed for use in equipment exposed to elevated ambient temperatures where long endurance at 125°C is needed.
• Automated surface‑mount assembly — Embossed carrier taping and chip‑type construction enable compatible placement on automated pick‑and‑place production lines.

Unique Advantages

• AEC‑Q200 qualification: Provides documented automotive-grade reliability for designs requiring industry-recognized stress qualification.
• Low‑temperature ESR control: ESR characterized after −40°C testing supports predictable impedance and performance across cold-to-hot transitions.
• High ripple handling: 850 mA (120 Hz) and 1.7 A (100 kHz) ripple current ratings reduce heating and improve lifetime under ripple stress.
• High‑temperature endurance: 3000 hours at 125°C offers long-term stability for sustained high‑temperature operation.
• SMD packaging for automated production: Embossed carrier tape and compact φ12.5 × 13.5 mm can format simplify high-volume surface‑mount manufacturing.
• Measured loss characteristics: tan δ of 0.16 (20°C, 120 Hz) and defined leakage current enable design verification against target power and leakage budgets.
