UCZ1H561MNS1MS

The UCZ1H561MNS1MS from Nichicon is a chip-type aluminum electrolytic surface-mount capacitor in the UCZ series designed for high-temperature, high-reliability applications. With a rated capacitance of 560 µF and a 50 V rating, it targets systems that require robust energy storage and filtering under elevated temperatures and mechanical stress.

Key value comes from a combination of high ripple capability, low ESR at high frequency, AEC-Q200 qualification, and endurance at 125 °C—features that support demanding automotive and harsh-environment designs while enabling automated PCB assembly via embossed carrier taping.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with ±20% tolerance and a 50 V rated voltage for bulk smoothing and energy storage on mid-voltage rails.
• High-temperature Endurance — Rated for operation from −40 °C to +125 °C with an endurance rating of 3500 hours at 125 °C.
• Low Loss Tangent — tan δ (DF) specified at 0.16 measured at 20 °C and 120 Hz, supporting predictable AC behavior at operating temperature.
• Low ESR & High Ripple Capability — ESR of 80 mΩ at 20 °C / 100 kHz, with ripple current ratings of 1 A at 120 Hz and 2 A at 10 kHz for improved high-frequency performance.
• Leakage Current — Specified leakage current of 280 µA, enabling controlled standby current profiles.
• Automotive-Grade Reliability — AEC-Q200 qualification and vibration resistance make this part suitable for automotive and other reliability-focused applications.
• Surface-Mount, Tape-and-Reel Ready — Chip-type radial can SMD package (φ16 × 16.5L) supplied in embossed carrier taping for automated pick-and-place assembly; recommended PCB land size: 1.63 × 1.63 cm.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification, −40 °C to +125 °C temperature range and vibration resistance support use in vehicle power systems and electronic control modules.
• Power Rail Smoothing — 560 µF capacitance, 50 V rating, and specified ripple currents suit bulk decoupling and filtering on 50 V power rails.
• High-temperature Embedded Systems — Endurance of 3500 hours at 125 °C and low loss tangent make this capacitor appropriate for electronics operating in sustained elevated temperatures.

Unique Advantages

• Designed for Elevated Temperatures: Endurance rated to 3500 hours at 125 °C provides predictable long-term performance in hot operating environments.
• High-Frequency Performance: 80 mΩ ESR at 100 kHz and a 2 A ripple rating at 10 kHz improve decoupling and reduce dissipation in high-frequency applications.
• AEC-Q200 Qualification: Enables use in reliability-sensitive automotive designs where qualification is required.
• Automated Assembly Friendly: Embossed carrier taping and an SMD radial can package support high-volume pick-and-place manufacturing.
• Robust Mechanical Stance: Vibration resistance reduces risk of mechanical failure in transport and mobile applications.
• Controlled Leakage and Loss: Specified leakage current (280 µA) and tan δ (0.16 at 120 Hz, 20 °C) ensure stable electrical behavior under rated conditions.
