UHD1E222MHD

The UHD1E222MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UHD series. It is a high-reliability, polarized capacitor with 2.2 mF (2200 µF) capacitance at 25 V and a temperature rating of −40 °C to +105 °C.

Designed for general-purpose electronic applications, the UHD1E222MHD delivers low impedance at high frequency and substantial ripple-current capability while occupying a compact φ12.5 × 35.5 mm can with 5 mm lead spacing. It is RoHS compliant and available in bulk or bag packaging for production quantities.

Key Features

• High capacitance in a compact can — 2200 µF nominal capacitance with ±20% tolerance in a φ12.5 × 35.5 mm radial package suitable for space-conscious designs.
• Rated for 25 V operation — Suitable for circuits requiring a 25 V polarized aluminum electrolytic solution.
• High ripple-current capability — Low-frequency ripple current 2.72 A (120 Hz) and high-frequency ripple current 3.4 A (100 kHz), enabling effective smoothing under load.
• Low dissipation factor — tan δ = 0.16 measured at 20 °C, 120 Hz, supporting lower losses in AC conditions.
• Controlled leakage current — Typical leakage current specified as 550 µA, measured after standard conditioning.
• Long endurance at elevated temperature — Rated for 5000 hours at 105 °C under endurance test conditions.
• Wide operating temperature range — −40 °C to +105 °C for use across varied environmental conditions.
• Radial lead, through-hole packaging — φ12.5 mm can with 5 mm lead spacing and lead-spacing tolerance ±0.5 mm for straightforward PCB mounting and assembly.
• RoHS compliant — Conforms to RoHS requirements as stated in the product data.

Typical Applications

• General-purpose electronic circuits — Bulk capacitance and energy storage for a wide range of general-purpose designs that require a radial-lead electrolytic.
• Power supply filtering — Smoothing and ripple reduction where high ripple-current handling and low impedance at higher frequencies are needed.
• High-reliability assemblies — Designs that require long endurance at elevated temperature (5000 h at 105 °C) and consistent performance over time.

Unique Advantages

• High ripple tolerance: Specified ripple currents of 2.72 A (120 Hz) and 3.4 A (100 kHz) help maintain stable filtering under AC loading.
• Low impedance at high frequency: UHD series design reduces impedance in the high-frequency range, improving decoupling effectiveness where it matters.
• Compact footprint: 2200 µF in a φ12.5 × 35.5 mm can lets you fit significant capacitance into constrained PCB real estate.
• Durable performance at elevated temperature: 5000-hour endurance at 105 °C supports long-term reliability in demanding environments.
• Clear electrical specifications: Defined tan δ (0.16 at 20 °C, 120 Hz) and leakage current (550 µA) allow predictable design margining and verification.
• Production-ready packaging: Available in bulk (no terminal forming) or bag packing for efficient PCB assembly workflows.
