UCZ1V821MNJ1MS

The UCZ1V821MNJ1MS is a surface-mount aluminum electrolytic chip capacitor delivering 820 µF at 35 V in a compact radial can SMD package (φ16 × 16.5L). It is built for high-temperature operation and automated assembly, offering a balance of high capacitance, low ESR, and long endurance for demanding electronic power applications.

Targeted use includes automotive and other high-temperature environments where AEC-Q200 qualification, extended lifetime at elevated temperature, and reliable ripple handling are required.

Key Features

• Capacitance & tolerance — 820 µF with ±20% tolerance measured at 120 Hz, 20°C for predictable bulk energy storage and decoupling.
• Voltage rating — 35 V rated voltage suitable for mid-voltage power rails and converter outputs.
• Low ESR — 47 mΩ ESR measured at 20°C/100 kHz, supporting improved power stability and reduced heat generation under high-frequency ripple.
• High ripple current capability — 1.2 A at 120 Hz (low frequency) and 2.4 A at 10 kHz (high frequency) for robust performance in switching and power-conversion circuits.
• High-temperature operation and endurance — Rated for −40°C to +125°C with a specified lifetime of 3500 hours at 125°C (φ16 × 16.5L case size).
• Loss angle (tan δ) — tan δ ≤ 0.16 at 120 Hz, 20°C for the 35 V rating, supporting predictable dissipation characteristics.
• Leakage current — Specified leakage current value of 287 µA, aligned with capacitor performance expectations under rated voltage.
• SMD radial can, tape packaging — φ16 × 16.5L radial can suitable for automatic mounting machines and supplied in embossed carrier taping for efficient assembly.
• AEC-Q200 qualified & RoHS compliant — Meets industry reliability expectations and environmental compliance requirements.

Typical Applications

• Automotive electronics — Energy storage and smoothing on power rails where AEC-Q200 qualification and +125°C endurance are required.
• High-temperature power modules — Bulk capacitance for converters and power stages operating in elevated ambient temperatures up to 125°C.
• Surface-mount power assemblies — Compact SMD radial can and embossed carrier tape packaging for automated assembly of high-density power boards.

Unique Advantages

• Extended high-temperature endurance: Specified 3500 hours at 125°C (φ16 × 16.5L), enabling longer life in hot operating environments.
• Strong ripple handling: 1.2 A (120 Hz) and 2.4 A (10 kHz) ripple ratings reduce stress on the capacitor in switching and high-frequency applications.
• Low ESR at high frequency: 47 mΩ at 100 kHz lowers power loss and improves voltage stability in fast-switching circuits.
• Assembly-ready package: Radial can SMD in embossed carrier tape supports automated placement and reflow-compatible manufacturing flows.
• Qualified reliability: AEC-Q200 qualification and RoHS compliance provide design assurance for regulated and safety-conscious markets.
