UFW1C222MHD

The UFW1C222MHD is a radial-lead aluminum electrolytic capacitor designed for audio equipment and related electronics. It delivers 2200 µF capacitance at a 16 V rating in a compact φ12.5 × 20 mm can with 5 mm lead spacing, offering high ripple handling and long endurance for through-hole designs.

Engineered for applications that require bulk energy storage, smoothing and decoupling in audio circuits, the part combines robust ripple-current performance with a wide operating temperature range and defined endurance at elevated temperature.

Key Features

• Capacitance & Voltage — 2.2 mF (2200 µF) nominal capacitance with ±20% tolerance and a 16 V rated voltage.
• Ripple Current Performance — Low-frequency ripple current of 1.25 A (120 Hz) and high-frequency ripple current of 1.438 A (10 kHz) to support audio power and filter applications.
• Endurance & Temperature — Rated for 2000 hours at 85 °C; operating temperature range of −40 °C to +85 °C for sustained performance in varied environments.
• Leakage & Loss Characteristics — Specified leakage current of 1056 µA for this part; datasheet leakage-current limits and tan δ limits are defined for design verification (e.g., tan δ max for 16 V is 0.20 at 120 Hz, 20 °C, with additional allowances for capacitances over 1000 µF).
• Package & Mounting — Radial-lead can (φ12.5 × 20 mm) suitable for through-hole mounting; lead spacing 5.0 mm with 0.5 mm tolerance and bulk/bag packing options.
• Marking — Printed marking in black on a gold sleeve for clear identification.

Typical Applications

• Audio amplifiers and preamplifiers — Bulk smoothing and power decoupling to support clean audio power rails and reduce ripple-related noise.
• Power supply filtering for audio systems — Input and output filter capacitors in linear and switch-mode supplies where higher ripple current capability is required.
• Crossover networks and signal conditioning — Energy storage and coupling where a polarized electrolytic capacitor with defined loss characteristics is appropriate.

Unique Advantages

• High ripple capability — Specifies both low-frequency and high-frequency ripple currents, enabling designers to match the part to real-world audio power profiles.
• Compact through-hole package — φ12.5 × 20 mm can and 5 mm lead spacing provide a small footprint for space-constrained PCBs while retaining through-hole robustness.
• Long endurance at elevated temperature — 2000 hours at 85 °C supports long-term reliability in applications exposed to elevated temperatures.
• Clear electrical specifications — Defined leakage current, tan δ guidance and frequency coefficients for ripple current allow predictable inclusion in simulation and BOM selection.
• Audio-focused series — Part of a series intended for audio equipment, with markings and construction tailored for that application space.
