UHW1C102MPD

The UHW1C102MPD is a radial-leaded aluminum electrolytic capacitor in Nichicon’s UHW series, designed for miniature, high-ripple-current applications. It delivers low impedance at high frequencies in a compact radial can package for general-purpose electronic designs.

This part provides 1 mF capacitance at a 16 V rating, polarized construction, and a combination of high ripple-current capability and long-term endurance for demanding power-conditioning roles in compact assemblies.

Key Features

• Capacitance & Voltage: 1 mF capacitance rated for 16 V operation, offering a bulk energy storage option in a small footprint.
• High Ripple Current: Rated ripple current of 1.2 A at 120 Hz and 2 A at 10 kHz, enabling effective AC ripple handling across low and high frequencies.
• Low High-Frequency Impedance: Specified impedance of 90 mΩ and datasheet guidance noting lower impedance at high frequency ranges to support decoupling and smoothing close to switching sources.
• Compact Radial Can Package: Radial lead mounting with 5 mm lead spacing and size L: 1.6 × D: 1 cm, suited for space-constrained PCBs.
• Temperature & Reliability: Rated operating temperature range −40°C to +105°C and endurance specified as 10,000 hours at 105°C for long-term reliability.
• Polarized Construction & Tolerance: Polarized aluminum electrolytic with tolerance −20% to +20% (±20%).

Typical Applications

• General-Purpose Electronics — Compact energy storage and smoothing where a miniature, high-ripple radial electrolytic capacitor is required.
• High-Frequency Power Conditioning — Situations that benefit from lower high-frequency impedance and specified ripple current at 10 kHz.
• PCB-Level Decoupling and Filtering — Radial lead format and low impedance support board-mounted filtering and smoothing close to power rails.

Unique Advantages

• High ripple capability: Rated ripple currents (1.2 A at 120 Hz; 2 A at 10 kHz) allow handling of substantial AC stresses without overspecifying larger packages.
• Low impedance at high frequency: 90 mΩ impedance and UHW series design characteristics reduce voltage ripple and improve transient performance where HF behavior matters.
• Space-efficient form factor: Small radial can (L: 1.6 × D: 1 cm) and 5 mm lead spacing help minimize PCB area for compact assemblies.
• Wide temperature range and endurance: −40°C to +105°C operation and 10,000-hour endurance at 105°C support long-term stability in thermally demanding environments.
• Manufacturer backing: Part of Nichicon’s UHW series, offering consistent series-level specifications for design predictability.
