UPM2A681MHD

The UPM2A681MHD is a miniature, high‑reliability aluminum electrolytic capacitor in a radial lead can designed for demanding power applications. It delivers 680 µF at a 100 V rating in a compact φ18 × 40 mm package with AEC‑Q200 qualification and a long endurance specification.

Engineered for high temperature and sustained load environments, this radial‑lead capacitor combines low impedance, defined ripple handling, and a wide operating temperature range (‑55 °C to +105 °C) for robust performance in systems where durability and stable capacitance matter.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance with a 100 V rated voltage and tolerance of ‑20% to +20% for energy storage and bulk filtering in high‑voltage circuits.
• High Temperature Endurance: Rated for 5000 hours at +105 °C, providing long life under elevated temperature and load conditions.
• Low Impedance: 36 mΩ impedance to support effective ripple attenuation and stable voltage regulation.
• Ripple Current Capability: Low‑frequency ripple current of 1.299 A (120 Hz) and high‑frequency ripple current of 1.91 A (200 kHz), enabling reliable performance across a range of switching and line frequencies.
• Loss Tangent / Dissipation Factor: tan δ = 0.08 (measured at 20 °C, 120 Hz), indicating controlled dielectric losses at the rated voltage.
• Leakage Current: Measured leakage current of 2040 µA, specified after rated voltage application conditions.
• Mechanical & Packaging: Radial lead mounting with φ18 × 40 mm size, 7.5 mm lead spacing (±0.5 mm), and supplied in bulk/bag packing; polarization noted for proper polarity installation.
• Compliance & Qualification: RoHS compliant and AEC‑Q200 qualified, supporting regulated and reliability‑focused applications.
• Production Status: Mass production availability for supply continuity.

Typical Applications

• Automotive systems: Suitable for automotive applications where AEC‑Q200 qualification, high voltage rating and high temperature endurance are required for power filtering and energy storage.

Unique Advantages

• High voltage capability: 100 V rating enables use in higher‑voltage power rails without series stacking.
• Compact high‑capacitance package: 680 µF in a φ18 × 40 mm can balances energy density and board‑space efficiency for through‑hole designs.
• Durability under heat and bias: 5000‑hour life at 105 °C supports designs requiring sustained operation at elevated temperatures.
• Robust ripple handling: Defined low‑ and high‑frequency ripple current ratings (1.299 A @120 Hz, 1.91 A @200 kHz) match both line‑frequency and switching environments.
• Low impedance for stable performance: 36 mΩ impedance helps reduce voltage drop and improve transient response in power electronics.
• Standards and compliance: AEC‑Q200 qualification and RoHS compliance provide traceable reliability and regulatory conformance.
