UPM2A121MHD

The UPM2A121MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPM series. It is a radial-lead, polarized can designed for applications requiring robust performance under elevated temperatures and continuous ripple stress.

With a rated capacitance of 120 µF at 100 V, low impedance characteristics and AEC-Q200 qualification, this capacitor targets power-handling roles in demanding electronics, including automotive and industrial systems that require long life at high operating temperatures.

Key Features

• Capacitance & Voltage — 120 µF capacitance rated at 100 V for bulk energy storage and smoothing in high-voltage circuits.
• Low Impedance — Specified impedance of 130 mΩ to support lower ESR in power filter and decoupling applications.
• Ripple Current Capability — Handles 371 mA at 120 Hz (low frequency) and 700 mA at 200 kHz (high frequency) for mixed-frequency ripple environments.
• High Reliability Endurance — Rated for 5000 hours at 105°C, providing predictable life under high-temperature, biased conditions.
• Loss Characteristics — tanδ = 0.08 measured at 20°C, 120 Hz for the 100 V rating, enabling stable AC performance.
• Leakage Current — Specified leakage current of 360 µA for predictable standby and charged-state behavior.
• Mechanical & Mounting — Radial lead package, size φ12.5 × 25 mm with 5 mm lead spacing (±0.5 mm), suitable for through-hole assemblies.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant; available in bulk/bag packing and in mass production status.

Typical Applications

• Automotive Electronic Modules — Energy storage and smoothing in power supply rails, leveraging AEC-Q200 qualification and 105°C endurance.
• Power Supply Filtering — Bulk filtering and ripple reduction in DC/DC converters and linear regulators due to low impedance and high ripple-current ratings.
• Industrial Control — Decoupling and energy buffering in motor drives and control boards where sustained high-temperature operation is required.
• High-Frequency Power Stages — Support for mixed-frequency ripple environments (120 Hz and 200 kHz) in switching power applications.

Unique Advantages

• Proven High-Temperature Endurance: 5000 hours at 105°C provides a predictable life profile for designs exposed to elevated ambient temperatures.
• Balanced Ripple Performance: Specified ripple currents at both low (371 mA @120 Hz) and high (700 mA @200 kHz) frequencies let a single component address multiple ripple sources.
• Compact Radial Can: φ12.5 × 25 mm size with 5 mm lead spacing delivers a space-efficient through-hole solution for designers needing reliable bulk capacitance.
• Low Loss and Low ESR: tanδ = 0.08 and impedance = 130 mΩ support efficient power delivery and reduced heating under load.
• AEC-Q200 Qualification: Qualification for automotive-grade reliability where industry-level stress qualification is required.
• Production-Ready Supply: Mass production status and standard packaging options (bulk/bag) support volume procurement and assembly workflows.
