UHW1J102MHD

The UHW1J102MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHW series. It is a radial-lead, polarized capacitor rated at 1000 µF and 63 V, designed for general-purpose power applications that require high ripple handling and low impedance across a wide frequency range.

Purpose-built for applications operating between −40°C and 105°C, this part delivers long endurance (12,000 hours at 105°C) and compact sizing (φ12.5 × 40 mm) for space-constrained power-filtering and energy-storage roles.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20%.
• High ripple current capability — Low-frequency ripple current of 1.86 A at 120 Hz and high-frequency ripple current of 3.1 A at 10 kHz for demanding power-filtering duties.
• Low impedance — Specified impedance of 95 mΩ and lower impedance characteristics at high frequency to improve filtering performance.
• Thermal endurance — Rated for operation from −40°C to +105°C with an endurance rating of 12,000 hours at 105°C under DC bias plus rated ripple current.
• Loss angle (tan δ) and leakage — tan δ of 0.09 (measured at 20°C, 120 Hz) and leakage current specified at 630 µA for this part.
• Compact radial package — φ12.5 × 40 mm can with radial leads; lead spacing 5.0 mm (±0.5 mm) and available in bulk or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• Power supply bulk filtering — Provides bulk energy storage and smoothing on DC rails where 63 V and 1000 µF are required.
• DC link and inverter support — Handles elevated ripple currents and reduces high-frequency impedance in DC link or intermediate bus circuits.
• Industrial and consumer power electronics — Suitable for general-purpose filtering in industrial controllers, power supplies, and consumer power modules that operate within −40°C to +105°C.

Unique Advantages

• High ripple handling: Rated ripple currents of 1.86 A (120 Hz) and 3.1 A (10 kHz) enable reliable performance in high-stress power-filtering environments.
• Compact high-capacitance form factor: 1000 µF in a φ12.5 × 40 mm can saves board space while delivering substantial stored energy.
• Low impedance at frequency: 95 mΩ impedance and series design characteristics reduce voltage ripple and improve regulator stability.
• Extended high-temperature life: Endurance of 12,000 hours at 105°C supports longevity in elevated-temperature installations.
• Predictable electrical behavior: Specified tan δ (0.09 at 20°C, 120 Hz) and defined leakage current provide measurable parameters for design margining.
• RoHS compliant packing options: Available in bulk (no terminal forming) or bag packing to fit assembly and procurement preferences.
