UPM1K181MHD

The UPM1K181MHD is an aluminum electrolytic capacitor from Nichicon’s UPM series, designed for low impedance and high reliability in radial-lead, can-style packaging. It provides 180 µF capacitance at an 80 V rating with ±20% tolerance and is intended for demanding electronic power applications.

Engineered for extended operation, the device supports a wide temperature range from -55°C to 105°C and a rated load-life of 5000 hours at 105°C, making it suitable for electronics requiring long-term stability and robust performance. The part is AEC-Q200 qualified and RoHS compliant.

Key Features

• Capacitance & voltage – 180 µF at 80 V with ±20% tolerance, providing bulk capacitance for power rail support and energy storage.
• Low impedance – Rated impedance of 130 mΩ helps reduce voltage ripple and losses under load.
• High ripple handling – Specified ripple currents of 396.9 mA at 120 Hz and 735 mA at 200 kHz support AC ripple and switching-power applications.
• Long endurance – 5000 hours rated life at 105°C (with lifecycle performance maintained within the specified limits for capacitance, tan δ and leakage).
• Wide temperature range – Operates from -55°C to 105°C to accommodate harsh thermal environments.
• Radial lead package – φ12.5 × 25 mm can with 5 mm lead spacing (±0.5 mm) for through-hole mounting and robust mechanical retention.
• Leakage and dissipation – Specified leakage current of 432 µA and tan δ of 0.08 at the rated voltage provide predictable loss characteristics for design calculations.
• Compliance and qualification – AEC-Q200 rating and RoHS compliance align the part with automotive and environmental standards.
• Packaging options – Available in bulk (no terminal forming) or bag packing to suit production assembly preferences.

Typical Applications

• Automotive electronics – AEC-Q200 qualification and -55°C to 105°C operation make this capacitor suitable for automotive electronic systems that demand reliability across temperature extremes.
• Power supply filtering – 180 µF capacitance combined with low impedance and defined ripple current ratings supports smoothing and decoupling on DC power rails.
• Industrial and embedded power modules – Long life at 105°C and predictable leakage/tan δ characteristics suit power modules and embedded systems requiring stable bulk capacitance over time.

Unique Advantages

• Proven endurance: 5000-hour load life at 105°C ensures sustained capacitance and loss performance for extended service intervals.
• Design-friendly electrical data: Clear specifications for impedance (130 mΩ), leakage (432 µA) and tan δ (0.08) enable accurate thermal and electrical margining.
• AEC-Q200 qualified: Qualification supports use in automotive-grade designs that require component-level assurance.
• Wide operating temperature: −55°C to 105°C rating expands deployment options across harsh environment applications.
• Through-hole robustness: Radial lead can and defined lead spacing (5 mm ±0.5 mm) provide mechanical durability and straightforward PCB mounting.
• RoHS compliant: Environmental compliance supports global manufacturing and regulatory requirements.
