UPJ1C821MHD6

The UPJ1C821MHD6 from Nichicon’s UPJ series is a miniature, radial-lead aluminum electrolytic capacitor rated at 820 µF and 16 V. It is a low-impedance, high-reliability component engineered for power filtering and decoupling in general-purpose and switching power supply applications.

Key value propositions include low impedance behavior for improved voltage stability, long endurance under elevated temperature (5,000 hours at 105°C for the applicable case sizes), and a wide operating temperature range of −55°C to +105°C.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance at a rated voltage of 16 V with tolerance ±20% (at 120 Hz, 20°C).
• Low loss (tan δ): Specified tan δ of 0.16 at 20°C, 120 Hz, supporting efficient energy transfer in power circuits.
• Low impedance, switching-ready: UPJ series is specified as low impedance and is described as ideally suited for switching power supplies.
• High ripple capability: Rated ripple currents of 644.4 mA at 120 Hz (low frequency) and 895 mA at 200 kHz (high frequency) for effective smoothing of AC components.
• Leakage current: Specified leakage current of 393.6 µA (measured per product conditions), supporting predictable bias behavior.
• Long endurance: Load-life endurance of 5,000 hours at 105°C (for applicable case sizes), with post-test limits of ±20% capacitance change and leakage current not exceeding initial specified value.
• Robust temperature range: Operating from −55°C to +105°C with low-temperature impedance characteristics defined in the series specifications.
• Radial-lead package: Compact can package φ12.5 × 15 mm (diameter × length) with 5.0 mm lead spacing and lead diameter 0.6 mm for standard through-hole mounting; available in bulk or bag packing.
• Regulatory status: RoHS compliant.

Typical Applications

• Switching power supplies: Low-impedance behavior and specified ripple ratings make this capacitor suitable for input/output smoothing and decoupling in DC–DC converters and SMPS modules.
• General-purpose power filtering: 820 µF capacitance and 16 V rating address bulk filtering and energy storage needs in consumer and industrial electronics.
• Embedded and control electronics: Compact radial-lead form factor and wide temperature range support use in board-level power regulation and filtering for control and instrumentation circuits.

Unique Advantages

• Low-impedance performance: Designed for reduced AC impedance, improving ripple suppression and voltage stability in power circuits.
• High-temperature endurance: Rated 5,000 hours at 105°C for the specified case sizes, delivering predictable long-term behavior under elevated operating conditions.
• Broad operating temperature range: −55°C to +105°C enables deployment across a wide set of environmental conditions without derating of core specifications.
• Dual-frequency ripple capability: Specified ripple current at both 120 Hz and 200 kHz provides quantifiable performance for low- and high-frequency filtering tasks.
• Compact radial package: φ12.5 × 15 mm can and 5.0 mm lead spacing provide a space-efficient through-hole solution for board-level power systems.
• RoHS compliant and mass-production ready: Availability in bulk/bag packing with mass production status supports volume procurement and assembly.
