UPJ1A820MDD

The UPJ1A820MDD is a miniature, polarized aluminum electrolytic capacitor from Nichicon's UPJ series, configured as a radial-lead can for through-hole mounting. It delivers 82 µF capacitance at a 10 V rating with a compact φ5 × 11 mm case and 2 mm lead spacing.

As a member of the UPJ series, this capacitor is designed around low-impedance characteristics suited for power filtering tasks in switching power supplies and general-purpose electronic applications, while offering a wide temperature range and defined ripple/current handling for reliable board-level performance.

Key Features

• Capacitance & voltage: 82 µF nominal capacitance with a rated voltage of 10 V and tolerance of ±20% (−20% to +20%).
• Low loss / impedance: Specified tangent of loss angle (tanδ) of 0.19 measured at 20°C, 120 Hz, indicating low-loss behavior for supply decoupling and filtering.
• Ripple current capability: Low-frequency ripple current 57.2 mA (120 Hz) and high-frequency ripple current 110 mA (200 kHz), supporting both mains-frequency and switching-frequency filtering.
• Leakage current: Low leakage current of 24.6 µA at rated conditions, minimizing standby and quiescent current impact.
• Temperature and endurance: Rated for operation from −55°C to +105°C with a specified endurance (life) of 2000 hours at 105°C.
• Compact radial package: φ5 × 11 mm radial can with 2.0 mm lead spacing (±0.5 mm tolerance), available in bulk or bag packing for through-hole assembly.
• RoHS compliant: Conforms to RoHS requirements as indicated in the product documentation.

Typical Applications

• Switching power supplies: Suitable for input/output filtering and decoupling in compact switching regulator designs where low impedance is valuable.
• General-purpose power filtering: Used for smoothing and energy storage on DC rails in a variety of consumer and industrial electronics.
• Compact board-level modules: Small φ5 × 11 mm can fits densely populated PCBs and space-constrained modules requiring through-hole radial components.

Unique Advantages

• Space-efficient form factor: Small φ5 × 11 mm can and 2 mm lead spacing enable use in compact assemblies without sacrificing capacitance.
• Measured low-loss performance: tanδ = 0.19 at 20°C, 120 Hz supports effective decoupling with predictable ESR-related behavior.
• Defined ripple handling across frequencies: Specified ripple current values at both 120 Hz and 200 kHz provide confidence for mains-frequency and switching-frequency filtering.
• Low leakage current: 24.6 µA leakage helps minimize parasitic drain on low-power rails and preserves standby efficiency.
• Wide operating temperature range: −55°C to +105°C rating supports use across varied thermal environments.
• Manufacturer pedigree: Part of Nichicon’s UPJ series, which documents low-impedance characteristics and switching-supply suitability at the series level.
