UPW0J821MPD

The UPW0J821MPD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UPW series. It delivers 820 µF at 6.3 V in a small φ8 × 15 mm can, designed for low impedance and high‑reliability filtering in compact power designs.

With an operating range of −55 °C to 105 °C, AEC‑Q200 rating, and a 3,000‑hour endurance at 105 °C, this part is intended for demanding applications where temperature resilience, ripple handling and stable capacitance are required.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance at a rated voltage of 6.3 V with tolerance of −20% to +20%.
• Low Loss / Tan δ — tanδ = 0.22 measured at 20 °C, 120 Hz for the 6.3 V rating, supporting efficient energy transfer in filtering roles.
• Low Impedance — 170 mΩ impedance helps reduce ripple voltage in power rails and improves transient response.
• High Ripple Current Capability — 547.5 mA at 120 Hz (low frequency) and 730 mA at 10 kHz (high frequency) to support switching power supply and DC‑DC converter applications.
• Reliability & Endurance — Rated life of 3,000 hours at 105 °C; leakage current specified as 154.98 µA, and endurance/shelf conditions defined by the UPW series datasheet.
• Package & Mounting — Radial lead can (φ8 × 15 mm) with 3.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for through‑hole assembly.
• Wide Temperature Range — Specified for operation from −55 °C to 105 °C for use in temperature‑challenging environments.
• Automotive‑Grade Qualification — AEC‑Q200 rating supports use in automotive applications where qualified components are required.

Typical Applications

• Automotive Power Conditioning — Filtering and smoothing in automotive power rails and auxiliary DC‑DC converters, leveraging the AEC‑Q200 rating and 105 °C endurance.
• Switching Power Supplies — Input/output smoothing and bulk decoupling for compact switching regulators, benefitting from low impedance and high ripple current capability.
• Industrial Control Electronics — Energy storage and ripple suppression in control modules exposed to wide temperature ranges (−55 °C to 105 °C).
• Backup and Hold‑up Circuits — Local energy reservoir for transient support where a compact, high‑capacitance through‑hole solution is required.

Unique Advantages

• Compact high capacitance: 820 µF in a φ8 × 15 mm can minimizes board footprint while providing substantial energy storage.
• High temperature endurance: 3,000 hours rated life at 105 °C supports sustained operation in elevated temperature environments.
• Low impedance and strong ripple performance: 170 mΩ impedance and up to 730 mA ripple current at high frequency reduce voltage ripple on power rails.
• Automotive‑grade qualification: AEC‑Q200 rating enables use in automotive electronic modules that require qualified components.
• Through‑hole reliability and ease of assembly: Radial lead package with standard 3.5 mm spacing and bulk/bag packing options for manual or wave solder assembly.
• Measured leakage and dissipation control: Specified leakage current (154.98 µA) and tanδ (0.22) allow predictable loss budgeting in design.
