UHW1E122MPD

The UHW1E122MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHW series, offering 1,200 µF capacitance at a 25 V rating in a compact φ10 × 25 mm can. Designed for general-purpose electronic power applications, it combines high ripple-current capability, low impedance at higher frequencies, and long-term endurance for demanding board-level decoupling and smoothing tasks.

This part is polarized, rated for operation from −40°C to +105°C, and is available in bulk or bag packing. It is in mass production and RoHS compliant.

Key Features

• Capacitance & Voltage — 1,200 µF capacitance at a 25 V rated voltage, with capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• High ripple-current capability — Low-frequency ripple current of 1.74 A (120 Hz) and high-frequency ripple current of 2.90 A (10 kHz), enabling effective filtering under AC ripple stress.
• Low impedance — Specified impedance of 51 mΩ, supporting improved high-frequency performance and transient response in power circuits.
• Long endurance — Rated life of 10,000 hours at 105°C, providing extended operational reliability in elevated-temperature environments.
• Temperature range — Wide operating range from −40°C to +105°C for stable behavior across typical industrial and consumer environments.
• Compact radial package — φ10 × 25 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assembly; available as Bulk (No Terminal Forming) or Bag packing.
• Electrical leakage & dissipation — Leakage current specified at 300 µA; tangent of loss angle (tan δ) of 0.13 at 20°C, 120 Hz for the rated voltage.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk capacitance and low impedance make the UHW1E122MPD suitable for smoothing and decoupling in DC power rails where 25 V rating is required.
• Switch-mode power supplies (SMPS) — High ripple-current capability supports input/output filtering and energy storage in compact SMPS designs.
• Board-level decoupling — Radial lead format and compact can size allow placement near regulators and power stages for improved transient response.

Unique Advantages

• High ripple endurance: Rated ripple currents of 1.74 A (120 Hz) and 2.90 A (10 kHz) reduce thermal stress and allow reliable operation under AC loading.
• Low ESR/Impedance: 51 mΩ impedance supports efficient filtering and lower voltage drop during high-current transients.
• Compact footprint: φ10 × 25 mm radial can delivers 1,200 µF in a small package to save board space without sacrificing performance.
• Extended high-temperature life: 10,000-hour endurance at 105°C provides predictable aging and long service life for high-temperature applications.
• Wide operating temperature: −40°C to +105°C range ensures functional stability across a broad set of environmental conditions.
• Production-ready packaging: Available in bulk or bag packing and listed as mass production for straightforward procurement and assembly planning.
