UPM1K121MPD

The UPM1K121MPD is a Nichicon UPM series aluminum electrolytic capacitor designed for low-impedance, high-reliability applications. It is a radial-lead, polarized can-type capacitor specified at 120 µF and 80 V with a compact φ10 × 30.5 mm package and 5 mm lead spacing.

Built for demanding temperature and endurance requirements, this part targets applications that require stable capacitance, controlled dissipation, and long life under elevated temperature conditions, notably in automotive environments where AEC-Q200 qualification and proven endurance matter.

Key Features

• Capacitance & Voltage — 120 µF rated capacitance at 80 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Low Impedance — Specified impedance of 180 mΩ to support effective ripple filtering and decoupling.
• Dissipation Factor (tan δ) — tanδ of 0.08 (measured at 20°C, 120 Hz, 80 V), for predictable AC loss behavior.
• Ripple Current Capability — Low-frequency ripple current 310.1 mA (120 Hz) and high-frequency ripple current 585 mA (200 kHz) to handle real-world ripple loads.
• Leakage Current — Typical leakage current 288 µA, specified after one minute at rated voltage and 20°C.
• High Endurance — Rated for 5,000 hours at 105°C when used within specification limits.
• Wide Temperature Range — Operating range from -55°C to +105°C for robust performance across harsh environments.
• Automotive-Grade Qualification — AEC-Q200 rating for suitability in automotive electronic designs.
• Package & Mounting — Radial lead, can-style package with φ10 mm diameter, 30.5 mm length, 5 mm lead spacing (±0.5 mm); supplied in bulk or bag packing.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Automotive electronic modules — Energy storage and ripple suppression in modules that require AEC-Q200 qualified components and long-term reliability at elevated temperatures.
• On-board power supplies — Bulk smoothing and decoupling where a compact 80 V, 120 µF radial can is required and where controlled impedance and ripple handling are important.
• Control and power electronics — Filtering and energy buffering in electronic control units and power regulation circuits operating across -55°C to +105°C.

Unique Advantages

• Long high-temperature life — 5,000 hours at 105°C delivers predictable end-of-life characteristics for designs exposed to sustained heat.
• Automotive-grade qualification — AEC-Q200 rating supports use in vehicle systems that require qualified components.
• Compact radial can — φ10 × 30.5 mm size with 5 mm lead spacing balances board area and capacitance for space-constrained assemblies.
• Measurable low impedance — 180 mΩ impedance specification supports effective noise suppression and power stability.
• Specified ripple and leakage — Clear low- and high-frequency ripple current ratings (310.1 mA @120 Hz, 585 mA @200 kHz) and leakage current (288 µA) simplify thermal and reliability calculations.
• Regulatory compliance — RoHS compliance for environmental and supply-chain alignment.
