UPM1K181MHD6

The UPM1K181MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, rated at 180 µF and 80 V. Designed for high-reliability applications, it combines low impedance and long endurance for demanding electronic power systems.

With AEC-Q200 qualification, a wide operating temperature range and a 5000‑hour endurance at 105°C, this part is targeted at automotive and industrial power applications that require stable filtering and decoupling under elevated temperature and long-life conditions.

Key Features

• Capacitance & Voltage: 180 µF capacitance rated for 80 V operation, with a tolerance of ±20% (120 Hz, 20°C).
• Low Impedance Performance: Typical impedance of 150 mΩ for reduced voltage ripple and improved transient response.
• Ripple Current Capability: Supports 294.3 mA at 120 Hz (low frequency) and 545 mA at 200 kHz (high frequency) to handle AC ripple in power circuits.
• Leakage and Loss: Specified leakage current of 432 µA and tanδ of 0.08 (measured at 20°C, 120 Hz), enabling predictable loss and charge retention behavior.
• High Temperature Endurance: Rated lifetime of 5000 hours at 105°C when used within specified conditions, supporting long-term reliability.
• Robust Environmental Range: Operating temperature from −55°C to +105°C and RoHS compliance for regulated designs.
• Package & Mounting: Radial lead can (φ16 × 15L) with 7.5 mm lead spacing (±0.5 mm), bulk or bag packing options for flexible assembly.
• Automotive-Grade Qualification: AEC-Q200 qualified for use in automotive electronics where that specification is required.

Typical Applications

• Automotive electronics: Filtering and smoothing in vehicle power systems where AEC-Q200 qualification and extended temperature range are required.
• On-board power supplies: Bulk capacitance and ripple handling for DC–DC converters and intermediate bus filtering.
• Industrial power control: Decoupling and energy storage in control modules exposed to elevated temperatures and long duty cycles.

Unique Advantages

• Long life at elevated temperature: 5000 hours at 105°C provides predictable endurance for designs requiring extended field life.
• Automotive-grade reliability: AEC-Q200 qualification supports use in regulated automotive applications and gives confidence in component robustness.
• Measured ripple performance: Documented low- and high-frequency ripple current ratings (294.3 mA at 120 Hz, 545 mA at 200 kHz) simplify selection for power-filtering duties.
• Low dissipation and leakage: tanδ of 0.08 and a specified leakage current of 432 µA enable controlled losses and stable operation in bias circuits.
• Compact radial package: φ16 × 15L can with 7.5 mm lead spacing provides a compact footprint for through-hole assembly and manual or wave insertion processes.
• Regulatory compliance: RoHS compliance supports deployment in regions with restricted substances requirements.
