UPJ1J121MPD

The UPJ1J121MPD is a radial-lead aluminum electrolytic capacitor offering 120 µF capacitance at a 63 V rating in a compact φ10 × 20 mm can. Designed for low-impedance power applications, it targets switching power supplies and general-purpose power-filtering tasks where stable performance and long life at elevated temperatures are required.

Key electrical characteristics include a loss tangent (tanδ) of 0.08 (measured at 20°C, 120 Hz), defined ripple current ratings for both low and high frequencies, and a rated operating temperature range of −55°C to +105°C with 5000 hours endurance at 105°C.

Key Features

• Low-impedance design — Specified for switching power supplies and power-filtering applications to support stable voltage regulation and reduced ripple.
• Electrical ratings — 120 µF nominal capacitance with ±20% tolerance and 63 V rated voltage; tanδ 0.08 at 20°C, 120 Hz.
• Ripple current specification — Low-frequency ripple current 294.15 mA (120 Hz) and high-frequency ripple current 555 mA (200 kHz), enabling use with both line-frequency and switching-frequency environments.
• Long-life thermal endurance — Rated for 5000 hours of load life at +105°C, supporting reliable long-term operation in elevated-temperature applications.
• Compact radial package — φ10 × 20 mm aluminum can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole PCB designs.
• Polarized, production-ready supply — Polarized electrolytic construction; available in bulk (no terminal forming) or bag packing; status: mass production.
• RoHS compliant — Conforms to RoHS requirements as noted in product documentation.

Typical Applications

• Switching power supplies — Low-impedance construction and specified ripple ratings make this capacitor suitable for output filtering and energy storage in switched-mode power supplies.
• DC-DC converters — Compact radial can and high ripple capability support use on converter input/output rails for smoothing and transient handling.
• Industrial power modules — 5000-hour endurance at 105°C and a wide operating temperature range (−55°C to +105°C) offer stability in industrial power electronics.
• Consumer and instrumentation power filtering — General-purpose decoupling and smoothing in consumer electronics, test equipment, and instrumentation where reliable power conditioning is required.

Unique Advantages

• Validated high-temperature endurance: 5000 hours at +105°C provides predictable long-term performance under continuous load.
• Dual-frequency ripple handling: Explicit ripple current ratings at 120 Hz and 200 kHz support both mains-frequency smoothing and high-frequency switching environments.
• Space-efficient form factor: φ10 × 20 mm radial can delivers 120 µF capacitance in a compact footprint for board-level through-hole designs.
• Clear electrical specifications: Defined tanδ, leakage current, and tolerance enable precise design margins and component selection.
• Production-ready packaging: Available in bulk or bag packing and listed as mass production for straightforward procurement and assembly planning.
• Regulatory compliance: RoHS compliance supports use in regions and products that require restriction of hazardous substances.
