UCZ1H681MNS1MS

The UCZ1H681MNS1MS is a chip-type aluminum electrolytic capacitor from the Nichicon UCZ series designed for surface-mount assembly and high-reliability applications. It delivers 680 µF at 50 V in an SMD can package with features targeted at elevated and low-temperature performance.

Key value propositions include operation across −40 °C to +125 °C, AEC-Q200 qualification for demanding environments, a low-temperature ESR specification with post −40 °C ESR verification, and compatibility with automatic carrier-tape mounting for streamlined production.

Key Features

• Chip-type SMD package — Radial can SMD construction designed for surface-mount placement and automatic carrier-tape feeding.
• Electrical rating — 680 µF nominal capacitance at a 50 V rated voltage with ±20% tolerance; polarized device suitable for DC filtering and energy storage on 50 V rails.
• Low-temperature ESR specification — ESR specified at low temperature and includes added ESR verification after a −40 °C test to ensure performance in cold conditions; nominal ESR: 78 mΩ at 100 kHz.
• Ripple handling — Rated ripple currents of 1.05 A at 120 Hz and 2.1 A at 10 kHz support AC ripple absorption and switching regulator loads.
• High-temperature endurance — Designed for continuous operation to +125 °C with a specified lifetime of 3500 hours at 125 °C.
• Assembly footprint — Compact dimensions (L: 1.65 × D: 1.8 cm) with recommended land size L: 1.83 × W: 1.83 cm to simplify PCB layout and automated placement.
• Standards and compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and high-reliability programs.

Typical Applications

• Automotive electronics — Suitable for automotive modules where AEC-Q200 qualification and operation to +125 °C are required.
• High-temperature electronics — Bulk energy storage and smoothing in electronics that operate at elevated ambient temperatures up to +125 °C.
• Surface-mount power assemblies — Carrier-tape compatible SMD can for automated placement in compact power or control assemblies.
• 50 V power rails — Bulk filtering and decoupling on 50 V supply lines, leveraging the 680 µF capacitance and specified ripple current ratings.

Unique Advantages

• Temperature-grade reliability: Rated for −40 °C to +125 °C with a defined 3500-hour endurance at 125 °C, enabling designs that must tolerate extended high-temperature operation.
• Low-temperature performance guaranteed: ESR is specified after a −40 °C test, providing verified low-temperature behavior for cold-start and low-ambient applications.
• Automated assembly ready: Carrier-tape compatible chip-type SMD can simplifies pick-and-place integration and high-volume manufacturing.
• High ripple capacity for switching supplies: Defined ripple current ratings at 120 Hz and 10 kHz support smoothing in switching regulator and power-conversion circuits.
• Industry qualification and compliance: AEC-Q200 qualification and RoHS compliance help meet regulatory and reliability requirements for regulated markets.
