UCZ1E821MNS1MS

The UCZ1E821MNS1MS is a chip-type aluminum electrolytic capacitor designed for high-reliability, surface-mount applications. It delivers 820 µF at 25 V in a compact SMD can package with polarization and carrier-tape compatibility for automated assembly.

Engineered for demanding thermal environments, this part is specified for operation from -40 °C to +125 °C, includes low‑temperature ESR specification (with added ESR data after -40 °C testing), and is AEC-Q200 qualified and RoHS compliant—making it suitable for automotive and other high-temperature electronics where long life and stable ESR are required.

Key Features

• Capacitance & Voltage: 820 µF rated capacitance at 25 V with ±20% tolerance, providing bulk energy storage for power rails and decoupling.
• High-temperature operation & endurance: Rated for -40 °C to +125 °C with a specified lifetime of 3000 hours at 125 °C, supporting prolonged use in elevated-temperature environments.
• Low-temperature ESR specification: ESR specified at low temperature with additional ESR data following -40 °C testing, enabling predictable performance across the stated temperature range; nominal ESR is 60 mΩ at 100 kHz.
• Ripple current capability: Handles 850 mA at 120 Hz (low frequency) and 1.7 A at 10 kHz (high frequency), suitable for smoothing and filtering in switching power supplies.
• Surface-mount, tape-fed package: Chip-type SMD can (radial, can - SMD) designed for automatic mounting machines fed with carrier tape; recommended land size 1.28 × 1.28 cm.
• Automotive-grade reliability: AEC-Q200 qualified and RoHS compliant, supporting use in applications requiring recognized quality standards.

Typical Applications

• Automotive electronic control units (ECUs): Bulk filtering and decoupling in ECUs where AEC-Q200 qualification and high-temperature endurance are required.
• Power conversion and DC–DC modules: Output smoothing and ripple suppression for converters operating with high ripple currents and elevated temperatures.
• Industrial high-temperature electronics: Energy storage and filtering in systems that must operate reliably between -40 °C and +125 °C.

Unique Advantages

• Temperature-qualified performance: Continuously rated to +125 °C with a 3000‑hour lifetime at that temperature, delivering predictable long-term behavior in hot environments.
• Low-temperature ESR reporting: Added ESR specification after -40 °C testing provides engineers with measurable ESR behavior across the full operating range for more accurate design margining.
• High ripple handling: Specified ripple currents at both low and high frequencies (850 mA @ 120 Hz, 1.7 A @ 10 kHz) that support demanding switching power applications.
• Automated assembly ready: Chip-type SMD can packaged for carrier-tape feeding simplifies integration into automated production lines.
• AEC-Q200 and RoHS compliance: Recognized qualification and environmental compliance that streamline selection for regulated or safety-focused designs.
