UPM1K121MHD6

The UPM1K121MHD6 is a Nichicon UPM series aluminum electrolytic capacitor offering 120µF capacitance at an 80V rating in a radial‑lead can (φ16×15L). It is part of a low‑impedance, high‑reliability family designed for applications that require robust electrical performance and long endurance.

Targeted for automotive and similar high‑reliability markets, this component combines AEC‑Q200 qualification, a wide operating temperature range of -55℃ to 105℃, and a 5000‑hour endurance at 105℃ for sustained performance under stress.

Key Features

• Capacitance & Voltage: 120µF rated at 80V for medium‑energy storage and decoupling in systems that require higher voltage handling.
• Low Impedance: Specified impedance of 200 mΩ to help minimize voltage ripple and improve transient response in power circuits.
• Loss Tangent (tan δ): tanδ = 0.08 (measured at 20℃, 120Hz), providing a quantifiable dissipation factor for design analysis.
• Ripple Current Capability: Low‑frequency ripple current 235.85 mA at 120Hz and high‑frequency ripple current 445 mA at 200 kHz, supporting both mains‑frequency and switching‑frequency ripple loads.
• Leakage Current: Specified leakage current 288 µA for predictable standby and bias behavior.
• High Endurance: Rated for 5000 hours at 105℃, supporting long life under elevated temperature and DC bias conditions.
• Automotive Qualification & Compliance: AEC‑Q200 qualified and RoHS compliant, aligning with regulatory and automotive reliability expectations.
• Package & Mechanical: Radial lead can, dimensions φ16×15L with 7.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing; status: mass production.
• Polarized Construction: Polarized aluminum electrolytic capacitor intended for typical polarized circuit placements.

Typical Applications

• Automotive power modules: Suited to automotive environments that require components qualified to AEC‑Q200 with operating temperatures from -55℃ to 105℃ and 5000‑hour endurance at 105℃.
• Vehicle DC link and smoothing: Designed for applications needing 80V rated capacitance and low impedance (200 mΩ) to manage ripple currents up to 445 mA at switching frequencies.
• Automotive electronic systems: Appropriate where predictable leakage current (288 µA), defined tanδ, and reliable lifetime are important for system-level stability and qualification processes.

Unique Advantages

• High voltage capability: 80V rating allows use in higher‑voltage automotive subsystems without stacking lower‑voltage parts.
• Quantified low loss and impedance: tanδ = 0.08 and 200 mΩ impedance provide measurable parameters for thermal and stability calculations.
• Dual‑frequency ripple support: Specified ripple currents at both 120Hz and 200kHz let designers account for mains and switching noise scenarios.
• Long endurance at elevated temperature: 5000 hours at 105℃ supports extended field life in demanding thermal environments.
• Automotive‑grade qualification: AEC‑Q200 rating and RoHS compliance ease integration into regulated automotive supply chains.
• Compact radial package: φ16×15L can with 7.5 mm lead spacing provides a space‑efficient through‑hole mounting option with standard radial assembly practices.
