UCZ2A820MNJ1MS

The UCZ2A820MNJ1MS is a chip-type aluminum electrolytic capacitor from Nichicon’s UCZ series engineered for high-reliability applications. It combines an 82 µF capacitance with a 100 V rating in a compact surface-mount radial can package designed for automated carrier-tape mounting.

Designed for extended operation across -40°C to +125°C and AEC-Q200 qualification, this capacitor targets demanding environments where high temperature endurance, controlled low-temperature ESR, and low leakage are required.

Key Features

• Electrical Performance — 82 µF capacitance at 100 V rated voltage with ±20% tolerance; polarized for DC applications.
• Low-temperature ESR Specification — ESR specified after -40°C testing; equivalent series resistance is 280 mΩ measured at 100 kHz.
• High-temperature Endurance — Rated for operation up to +125°C with a specified lifetime of 3000 hours at 125°C.
• Ripple Current Capability — Rated ripple currents of 350 mA at 120 Hz and 700 mA at 10 kHz support power smoothing and decoupling under AC ripple conditions.
• Leakage Current — After 2 minutes at rated voltage and 20°C, leakage current is specified ≤ 0.01CV (µA), enabling predictable standby and bias performance.
• Package and Mounting — Surface-mount radial can (SMD) with dimensions L: 1.35 × D: 1.25 cm and recommended land pattern L: 1.28 × W: 1.28 cm for automated carrier-tape placement.
• Reliability & Compliance — AEC-Q200 Qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting use in regulated environments.
• Low-temperature Stability — Impedance ratio at -40°C is specified (measured at 120 Hz), with a maximum impedance ratio up to 3 for 100 V devices, providing controlled performance in cold conditions.

Typical Applications

• Automotive Power Electronics — Suitable for 100 V automotive power rails where high-temperature endurance and AEC-Q200 qualification are required.
• Power Rail Smoothing and Decoupling — Use on high-voltage DC rails for ripple attenuation and decoupling thanks to the 82 µF/100 V rating and defined ripple current capability.
• High-temperature Electronics — Electronics exposed to sustained high temperatures up to +125°C that require stable capacitance and low leakage over long endurance periods.

Unique Advantages

• High-temperature capability: Rated to +125°C and specified for 3000 hours at that temperature, enabling predictable long-term performance in hot environments.
• Low-temperature ESR control: ESR is specified following -40°C testing and measured at 100 kHz, reducing design uncertainty for cold-start and low-temperature operation.
• Automated assembly ready: Designed for carrier-tape feeding and surface-mount placement, simplifying integration into high-volume production lines.
• Defined ripple performance: Specified ripple current ratings at both 120 Hz and 10 kHz allow engineers to match the capacitor to AC ripple profiles in power systems.
• Traceable reliability: AEC-Q200 qualification and RoHS compliance provide documented suitability for regulated, high-reliability applications.
