UHW1C122MPD

The UHW1C122MPD is a radial-lead aluminum electrolytic capacitor with 1.2 mF capacitance at a 16 V rating, designed for general-purpose electronic power applications. It combines a compact φ10×20 mm can and radial-lead mounting with high ripple current capability and a long endurance rating.

Engineered for designs that require bulk capacitance on low-voltage rails, this part delivers low impedance, measurable loss characteristics, and a wide operating temperature range for reliable operation in demanding assemblies.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a 16 V rated voltage and tolerance of −20% to +20%.
• High ripple current capability — Low-frequency ripple current rated at 1.5 A (120 Hz) and high-frequency ripple current rated at 2.5 A (10 kHz), supporting applications with significant AC content on DC rails.
• Low impedance — Specified impedance of 60 mΩ, providing improved power delivery and reduced voltage ripple under load.
• Frequency performance — Lower impedance at high frequency is a designed characteristic of the UHW series, supporting stability of high-frequency converter and switching circuits.
• Size and mounting — Compact radial-can package, φ10×20 mm with 5 mm lead spacing (±0.5 mm), for through‑hole mounting and straightforward board-level integration.
• Temperature and endurance — Rated for operation from −40 °C to +105 °C with an endurance life of 10,000 hours at 105 °C.
• Electrical loss and leakage — Specified tangent of loss angle (tanδ) of 0.15 at 20 °C, 120 Hz, and a measured leakage current of 192 µA.
• Packaging & production status — Available in bulk (no terminal forming) / bag packing and currently in mass production.
• RoHS compliant — Meets RoHS directive requirements as indicated for the UHW series.

Typical Applications

• Power supply filtering — Bulk energy storage and smoothing on low-voltage (16 V) rails where 1200 µF and high ripple tolerance reduce output ripple and improve regulator stability.
• DC/DC converters — Input and output decoupling in switching converters that require low impedance and elevated high-frequency ripple handling.
• General-purpose power conditioning — Applications requiring a compact, radial-lead polarized capacitor with long life at elevated ambient temperatures.

Unique Advantages

• High ripple handling at both low and high frequencies — Dual ripple ratings (1.5 A at 120 Hz and 2.5 A at 10 kHz) let designers specify one part for mixed-frequency ripple environments.
• Compact radial-can footprint — φ10×20 mm size with 5 mm lead spacing delivers 1.2 mF capacitance in a small through-hole form factor for space-constrained boards.
• Long-term reliability at elevated temperature — 10,000 hours endurance at 105 °C provides predictable lifetime performance for thermal-stressed applications.
• Low impedance for improved transient response — 60 mΩ impedance helps maintain voltage stability under dynamic load conditions.
• Measured electrical characteristics — Specified tanδ and leakage current values support engineering verification and failure-mode analysis.
• RoHS compliance and production readiness — Environmentally compliant and available in mass production quantities with bag/bulk packing options.
