UPJ1H3R3MDD

The UPJ1H3R3MDD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, offering a 3.3 µF capacitance at a 50 V rated voltage. It is a polarized, low-impedance device designed for general-purpose power applications and is particularly suitable for use in switching power supplies.

Key electrical and mechanical characteristics include a compact φ5 × 11 mm can, 2 mm lead spacing, a wide operating temperature range of −55°C to +105°C, and a specified endurance of 2000 hours at 105°C. The part is RoHS compliant and supplied in bulk or bag packing.

Key Features

• Electrical Rating: 3.3 µF capacitance at 50 V with ±20% tolerance, providing predictable decoupling and energy storage for power circuits.
• Low Loss (tan δ): tan δ = 0.1 measured at 20°C, 120 Hz, indicating low dissipation for improved efficiency in AC/ripple conditions.
• Ripple Current Capability: Low-frequency ripple current 16.5 mA at 120 Hz and high-frequency ripple current 33 mA at 200 kHz for handling AC ripple in power applications.
• Leakage Current: Specified leakage current of 4.95 µA, supporting stable bias performance after voltage application.
• Thermal and Endurance Performance: Rated for −55°C to +105°C operation with a life/endurance rating of 2000 hours at 105°C.
• Radial Lead Package: Compact φ5 × 11 mm can with 2 mm lead spacing (±0.5 mm tolerance) for through-hole PCB assembly; available in bulk (no terminal forming) or bag packing.
• Compliance: RoHS compliant as supplied.

Typical Applications

• Switching Power Supplies: Low-impedance construction and specified ripple current ratings make this part suitable for output filtering and decoupling in switching regulators.
• General-Purpose Power Filtering: Used for bulk decoupling and smoothing in power rails where a compact, polarized electrolytic is required.
• Through-Hole PCB Assemblies: Radial-lead form factor with 2 mm lead spacing fits dense through-hole layouts and manual or wave-solder assembly processes.

Unique Advantages

• Compact Footprint: φ5 × 11 mm can and 2 mm lead spacing optimize board space in compact power modules and assemblies.
• Measured Low Loss: tan δ = 0.1 at 20°C/120 Hz reduces dissipation under AC conditions, supporting more efficient power-stage operation.
• Dual-Frequency Ripple Ratings: Specified ripple currents at both 120 Hz and 200 kHz provide clear guidance for low- and high-frequency filtering needs.
• Wide Temperature Range: −55°C to +105°C rating enables use across broad ambient and thermal conditions.
• Traceable Endurance Spec: Lifetime specified as 2000 hours at 105°C for predictable long-term performance in high-temperature environments.
• Regulatory Compliance: RoHS compliant for inclusion in assemblies targeting restricted-substance conformity.
