UPJ1J120MDD

The UPJ1J120MDD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPJ series, offering a 12 µF capacitance at a 63 V rating. Designed as a low-impedance, polarized power capacitor, it targets general-purpose power filtering and decoupling in compact assemblies.

With a wide operating temperature range of -55°C to 105°C and low-loss characteristics (tan δ = 0.08 at 63–100 V), this part is aimed at applications that require reliable power smoothing and ripple handling in small package footprints.

Key Features

• Capacitance & Voltage — 12 µF rated capacitance with a 63 V working voltage and ±20% tolerance, suitable for mid-voltage power rails.
• Low Loss / Low Impedance — tan δ of 0.08 (63–100 V rating) supports lower dissipation and improved AC performance for power supply decoupling.
• Leakage Current — Specified leakage current of 22.68 µA, providing predictable DC behavior during hold and standby conditions.
• Temperature & Reliability — Operates from -55°C to 105°C with specified lifetime of 2000 hours at 105°C, supporting designs that require sustained elevated-temperature performance.
• Form Factor & Mounting — Compact radial can (φ5 × 11 mm) with 2 mm lead spacing and radial lead mounting for through-hole PCB assemblies.
• Packaging — Supplied in bulk (no terminal forming) or bag packing to accommodate common manufacturing flows.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Switching power supplies — Low-impedance UPJ series design supports filtering and output smoothing in switching regulator stages.
• Power supply decoupling — Provides bulk smoothing and transient support on mid-voltage rails up to 63 V.
• General-purpose electronic equipment — Suited for compact through-hole boards where radial-lead capacitors are preferred for repairability and prototyping.

Unique Advantages

• Compact radial can — φ5 × 11 mm footprint and 2 mm lead spacing reduce PCB area for space-constrained designs.
• Predictable leakage behavior — Specified leakage current (22.68 µA) enables reliable biasing and low-standby power calculations.
• Wide temperature operation — -55°C to 105°C rating supports designs that must operate across broad environmental ranges.
• Low-loss characteristic — tan δ = 0.08 at this voltage rating reduces internal heating and improves AC performance for ripple handling.
• Series pedigree — Part of the UPJ family, which is positioned for low-impedance power applications such as switching regulators.
• RoHS compliance — Facilitates regulatory alignment in modern electronic assemblies.
