UPM1E821MHD6

The UPM1E821MHD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, designed for high-reliability power filtering and energy-storage applications. It provides 820 µF capacitance at a 25 V rating in a compact φ16×15L radial can with 7.5 mm lead spacing and is intended for demanding environments with an operating range of −55°C to 105°C.

Targeted use cases include board-level power smoothing, decoupling and energy buffering in industrial and AEC‑Q200 qualified systems where long life and stable electrical performance are required.

Key Features

• Capacitance & voltage: 820 µF at a 25 V rated voltage for bulk energy storage and smoothing on DC rails.
• Low impedance: 49 mOhm impedance for reduced voltage ripple and improved transient response in power circuits.
• Ripple current capability: 820.8 mA at 120 Hz (low frequency) and 1.14 A at 200 kHz (high frequency) to support continuous ripple handling in switching and linear power supplies.
• High reliability endurance: Rated for 5000 hours at 105°C under DC bias plus rated ripple current to support long-term operation at elevated temperature.
• Temperature range: −55°C to 105°C for broad thermal compatibility across harsh and variable environments.
• Loss tangent (tan δ): 0.14 measured at 20°C, 120 Hz, enabling predictable dissipation characteristics for thermal and circuit design.
• Leakage current: Specified leakage current 615 µA for predictable standby and bias behavior.
• Mechanical & packaging: Radial-lead can (φ16×15L) with 7.5 mm lead spacing (±0.5 mm tolerance); available in bulk (no terminal forming) or bag packing for flexible assembly workflows.
• AEC‑Q200 qualified and RoHS compliant: Meets AEC‑Q200 qualification and RoHS directive requirements for regulated substance compliance.

Typical Applications

• Power supply smoothing: Bulk capacitance and low impedance make the UPM1E821MHD6 suitable for smoothing and decoupling DC power rails in power supply modules.
• Switching regulator output filtering: High ripple current capability at both low and high frequencies supports use on switching regulator outputs and post‑regulation stages.
• Industrial control electronics: Long endurance at 105°C and wide temperature range support reliable energy buffering in industrial control and instrumentation systems.
• Automotive-qualified modules: AEC‑Q200 qualification enables use in vehicle electronic modules where automotive-grade components are required.

Unique Advantages

• Compact high-capacitance package: 820 µF in a φ16×15L radial can saves board space while delivering substantial energy storage for bulk filtering.
• Predictable thermal and electrical behavior: Specified tan δ, leakage current and impedance values provide designers with measurable parameters for thermal and stability calculations.
• Robust ripple handling: Clear low- and high-frequency ripple current ratings allow confident selection for both line-frequency and switching-frequency applications.
• Long endurance at elevated temperature: 5000 hours at 105°C ensures extended service life in high-temperature operating profiles.
• Industry qualification and compliance: AEC‑Q200 qualification and RoHS compliance simplify regulatory and quality acceptance for regulated applications.
• Flexible assembly options: Radial lead form and bulk or bag packaging accommodate manual assembly and automated processes that accept radial components.
