UHE1J121MPD

The UHE1J121MPD is a radial-lead aluminum electrolytic capacitor in Nichicon's UHE series, offering 120 µF capacitance at a rated voltage of 63 V. Designed for general-purpose electronics, this compact φ8 × 20 mm can delivers low loss (tanδ = 0.09 at 20°C, 120 Hz) and measurable ripple-handling capability across both low and high frequencies.

With an operating temperature range of −40°C to 105°C and a guaranteed endurance of 7000 hours at 105°C, the UHE1J121MPD addresses applications that require reliable smoothing, decoupling and bulk energy storage in a small radial package with 3.5 mm lead spacing.

Key Features

• Capacitance & Voltage — 120 µF rated capacitance at 63 V for mid-voltage energy storage and decoupling duties.
• Low Loss Performance — tanδ = 0.09 measured at 20°C, 120 Hz, supporting efficient AC performance in filtering applications.
• Ripple Current Capability — Rated ripple current of 285.6 mA at 120 Hz and 408 mA at 10 kHz to handle both low- and high-frequency ripple components.
• Leakage Current — Specified leakage current of 75.6 µA for predictable standby and bias conditions.
• High-Temperature Endurance — 7000 hours life rating at 105°C for reliable long-term operation under elevated temperature stress.
• Compact Radial Package — φ8 × 20 mm can with 3.5 mm lead spacing (±0.5 mm), available in bulk/bag packing for through-hole assembly.
• Wide Operating Range — Rated for −40°C to 105°C to suit consumer, industrial and general-purpose electronics environments.

Typical Applications

• General-Purpose Electronics — Used wherever a 120 µF, 63 V polarized capacitor is required for bulk storage or smoothing in through-hole designs.
• Power Supply Filtering — Supports input/output smoothing and ripple reduction with rated ripple currents of 285.6 mA (120 Hz) and 408 mA (10 kHz).
• Decoupling and Local Energy Storage — Compact φ8 × 20 mm radial can provides local capacitance near regulators and converters to stabilize voltage rails.

Unique Advantages

• Measurable Ripple Handling: Specified ripple current values at both 120 Hz and 10 kHz allow designers to size capacitors precisely for mixed-frequency power environments.
• Predictable Leakage: Low leakage current (75.6 µA) provides consistent bias performance and simplifies system-level leakage budgeting.
• High-Temperature Reliability: 7000 hours endurance at 105°C supports long-term operation in thermally demanding applications.
• Low Dissipation Factor: tanδ = 0.09 at standard test conditions reduces heat generation and energy loss in AC conditions.
• Space-Efficient Through-Hole Format: Small φ8 × 20 mm can with standard 3.5 mm lead spacing fits compact PCB layouts while remaining easy to install in through-hole assemblies.
