UHW1J121MPD

The UHW1J121MPD from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in the UHW series designed for radial-lead mounting. It delivers 120 µF capacitance at 63 V with a compact φ8 × 15 mm can and 3.5 mm lead spacing for space-constrained assemblies.

Designed for general-purpose electronic applications that require low impedance and elevated ripple-current capability, this part combines long endurance at elevated temperature with RoHS compliance for broad use in commercial and industrial designs.

Key Features

• Capacitance & Voltage — 120 µF rated capacitance with a 63 V working voltage and ±20% tolerance, suitable for general-purpose filtering and energy storage roles.
• Low Impedance — 900 mΩ impedance (specified at 120 Hz, 20 °C) and a loss tangent (tanδ) of 0.09 at 63 V, 120 Hz, enabling effective high-frequency performance.
• High Ripple Current — Low-frequency ripple current rated at 492 mA (120 Hz) and high-frequency ripple current rated at 1.23 A (10 kHz), supporting circuits with significant AC ripple demands.
• Leakage Current — Specified leakage current of 75.6 µA, providing predictable static performance after voltage application.
• Thermal and Endurance Performance — Operating range from −40 °C to +105 °C with an endurance rating of 11,000 hours at 105 °C.
• Compact Radial Package — φ8 × 15 mm can, radial lead mounting with 3.5 mm lead spacing (±0.5 mm), available in bulk or bag packing for flexible assembly handling.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power Supply Filtering — Use for smoothing and filtering where moderate capacitance and 63 V rating are required, leveraging the high ripple-current capability and low impedance.
• Compact Industrial Electronics — Suited to space-constrained power circuits thanks to its miniature φ8 × 15 mm can and radial-lead package.
• General-Purpose Electronic Circuits — Applicable across a wide range of general-purpose designs that require reliable capacitance, defined leakage, and long-term endurance at elevated temperature.

Unique Advantages

• High ripple-current handling: Rated for 492 mA at 120 Hz and 1.23 A at 10 kHz, enabling robust operation in circuits with significant AC content.
• Predictable AC performance: Low impedance (900 mΩ) and tanδ of 0.09 provide stable high-frequency behavior for decoupling and filtering tasks.
• Long endurance at high temperature: 11,000-hour life at 105 °C supports prolonged reliability in high-temperature environments.
• Small footprint: φ8 × 15 mm can with radial leads and 3.5 mm spacing helps reduce board area without sacrificing ripple capability.
• Controlled leakage: Specified leakage current of 75.6 µA ensures predictable standby and static current behavior.
• Regulatory compliance: RoHS compliance simplifies use in regions and products with restricted substance requirements.
