UCZ2A181MNJ1MS

The UCZ2A181MNJ1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature operation up to +125°C. It combines a 180 µF capacitance with a 100 V rating in a surface-mount, tape-fed can package targeted at reliability-critical designs.

Engineered for applications that require elevated temperature endurance and predictable low-temperature ESR behavior, this AEC-Q200 qualified, RoHS-compliant part supports automated PCB assembly and long-term operation in demanding environments.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance for bulk energy storage and decoupling at higher bus voltages.
• High temperature range — Operates from −40 °C to +125 °C, enabling use in elevated-temperature environments and thermally demanding assemblies.
• AEC-Q200 qualified — Meets AEC-Q200 qualification for use in applications requiring component-level automotive reliability.
• Low-temperature ESR specification — ESR characterized including measurement after −40 °C testing; specified ESR is 170 mOhm at 100 kHz, supporting predictable behavior across temperature extremes.
• Long high-temperature lifetime — Rated for 3,500 hours at 125 °C, suitable for designs requiring sustained performance at elevated temperatures.
• Ripple current capability — Rated ripple current of 550 mA at 120 Hz and 1.1 A at 10 kHz to support filtering and smoothing in power circuits.
• Surface-mount, tape-fed can — Chip-type radial can packaged for surface-mount assembly and applicable to automatic mounting machines fed with carrier tape for efficient production.
• Regulatory compliance — RoHS compliant (2011/65/EU,(EU)2015/863).
• Compact footprint — Physical dimensions L: 1.65 × D: 1.8 cm with recommended land size L: 1.83 × W: 1.83 cm for PCB layout planning.

Typical Applications

• Automotive electronics — Bulk filtering and energy storage in control modules and power electronics where AEC-Q200 qualification and +125 °C performance are required.
• Power supply filtering — Input/output smoothing and decoupling on high-voltage rails up to 100 V in compact SMD assemblies.
• Industrial control — High-temperature-capable decoupling and bulk capacitance for sensor interfaces and control boards exposed to elevated ambient temperatures.
• Surface-mount production — Designed for automated placement with carrier tape compatibility to streamline high-volume assembly of robust power subsystems.

Unique Advantages

• Elevated-temperature reliability: Rated for operation to +125 °C with a 3,500-hour endurance at that temperature, providing predictable lifetime in hot environments.
• AEC-Q200 qualification: Component-level qualification supports selection for safety- and reliability-focused automotive and transportation designs.
• Measured low-temperature performance: ESR specified after −40 °C testing ensures consistent impedance behavior across cold-start and low-temperature conditions.
• High voltage capability: 100 V rating allows use on higher-voltage rails without sacrificing compact SMD packaging.
• Assembly-friendly packaging: Tape-fed surface-mount can format enables automated placement and simplifies BOM handling for volume production.
• Clear electrical margins: Specified ripple currents at both low and high frequencies (550 mA at 120 Hz, 1.1 A at 10 kHz) make it straightforward to size the capacitor for real-world power circuits.
