UHW2A470MPD

The UHW2A470MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can. Designed for general-purpose power applications, it delivers a compact 47 µF capacitance at a 100 V rating with construction optimized for high ripple current and low high-frequency impedance.

This radial-lead polarized capacitor suits circuits that require robust ripple handling, broad operating temperature capability, and long-term endurance under elevated temperature conditions.

Key Features

• Capacitance & Voltage — 47 µF capacitance rated at 100 V, with a tolerance of −20% to +20%.
• High ripple capability — Low-frequency ripple current 492 mA (120 Hz) and high-frequency ripple current 1.23 A (10 kHz) to support demanding AC components on DC rails.
• Low loss and impedance — Dissipation factor (tanδ) of 0.08 (measured at 20°C, 120 Hz) and an impedance of 900 mΩ for improved AC performance and thermal behavior.
• Miniature radial package — Compact φ8 × 15L can with 3.5 mm lead spacing and lead diameter 0.6 mm, enabling space-efficient through-hole placement.
• Wide temperature and long life — Rated for −40°C to +105°C operation with an endurance specification of 11,000 hours at 105°C.
• Leakage current — Specified leakage current of 47 µA after rated voltage application.
• Packaging & production — Available in bulk (no terminal forming) or bag packing; status: mass production. RoHS compliant.

Typical Applications

• General-purpose power filtering — 47 µF at 100 V provides bulk decoupling and smoothing where a polarized through-hole capacitor is required.
• High-ripple power rails — Rated ripple currents (492 mA @120 Hz; 1.23 A @10 kHz) make it suitable for supplies with significant AC ripple components.
• Extended-temperature systems — Operation from −40°C to +105°C and 11,000-hour endurance at 105°C support long-term performance in thermally stressed environments.

Unique Advantages

• Compact footprint with robust performance — φ8 × 15L package delivers 47 µF at 100 V in a small radial can, conserving board space without sacrificing ripple capacity.
• High-frequency performance — Lower impedance at high frequency and a low tanδ (0.08) improve AC response and reduce heating under ripple conditions.
• Designed for longevity at elevated temperature — 11,000-hour endurance at 105°C provides predictable drift and stability for long-life power designs.
• Measured leakage and impedance specs — Specified leakage current (47 µA) and impedance (900 mΩ) enable straightforward thermal and reliability planning.
• Board-ready radial form — Standard 3.5 mm lead spacing and 0.6 mm lead diameter make it easy to integrate into through-hole layouts and legacy designs.
• Supply chain readiness — Mass-production status and RoHS compliance simplify sourcing and regulatory acceptance.
