UPM1E821MHD

The UPM1E821MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, engineered for low impedance and high reliability. It offers 820 µF capacitance at a 25 V rating with polarized radial leads and is designed for applications that require sustained performance across a wide temperature range.

Key value propositions include a long 5,000-hour load life at 105°C, AEC-Q200 qualification, low impedance and measurable ripple-current capability — making it suitable for demanding power and electronic control applications.

Key Features

• Capacitance & Voltage: 820 µF rated capacitance at 25 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Low Impedance: Specified impedance of 41 mΩ, supporting tighter voltage stability under load.
• High Reliability / Long Life: Endurance specified as 5000 hours at +105°C under rated conditions, aligned with the UPM series reliability targets.
• Ripple Current Capability: Handles 878.4 mA at 120 Hz and 1.22 A at 200 kHz, providing effective ripple filtering in power circuits.
• Loss Characteristics: Tangent of loss angle (tan δ) of 0.14 at the 25 V rating (measured at 120 Hz, 20°C), for predictable dissipation behavior.
• Leakage Current: Specified leakage current of 615 µA after application of rated voltage (measurement conditions per product data).
• Temperature Range: Operates from −55°C to +105°C, supporting a broad range of environmental conditions.
• Package & Mounting: Radial, can-style package with size φ12.5 × 20 mm (L: 2.0 cm × D: 1.25 cm); lead spacing 5.0 mm (tolerance ±0.5 mm). Packaging available in bulk (no terminal forming) or bag packing.
• Standards & Compliance: AEC-Q200 qualified and RoHS compliant, as provided in the product information.

Typical Applications

• Automotive Electronics: Energy smoothing and decoupling in vehicle electronic modules where AEC-Q200 qualification and high-temperature endurance are required.
• Power Supply Filtering: Bulk smoothing and ripple suppression for DC-DC converters and regulated supplies, leveraging the capacitor’s high ripple-current ratings and low impedance.
• Motor Control & Power Modules: Local energy reservoir and transient suppression in motor drivers and power-control boards that require robust electrolytic bulk capacitance.

Unique Advantages

• Long High-Temperature Life: 5000-hour endurance at 105°C supports designs with extended elevated-temperature operation, reducing maintenance cycles.
• Measurable Low Impedance: 41 mΩ impedance provides lower voltage drop under ripple and transient loads, improving power-stage stability.
• High Ripple Handling: Rated ripple currents of 878.4 mA (120 Hz) and 1.22 A (200 kHz) enable effective smoothing across low and high-frequency domains.
• AEC-Q200 Qualified: Recognized qualification for applications requiring industry-recognized component-level robustness.
• Compact Through-Hole Form Factor: φ12.5 × 20 mm radial can with 5.0 mm lead spacing simplifies retrofits and through-hole PCB designs.
• RoHS Compliant: Conforms to RoHS directive requirements for environmental compliance.
