UDB1H470MHM

The UDB1H470MHM is a bi‑polarized aluminum electrolytic capacitor engineered for audio use, specifically designed for crossover networks in Hi‑Fi sound systems. It provides 47 µF capacitance at a 50 V rating in a radial‑lead can package suitable for through‑hole mounting.

Key value comes from its audio‑focused design and clear electrical specifications — including leakage current, tangent of loss angle and rated ripple — combined with RoHS compliance for environmental regulation adherence.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance at 50 V, specified with ±20% tolerance.
• Bi‑Polar Construction — Bi‑polarized design intended for audio circuits and speaker crossover networks; suitable where polarity‑free AC coupling is required.
• Audio‑Oriented Performance — Tangent of loss angle (tan δ) specified at 0.10 or less (1 kHz) and 0.15 or less (5 kHz), supporting predictable AC behavior in audio frequencies.
• Leakage Current Specification — Leakage current limited to not more than 0.03CV or 3 µA (whichever is greater) after five minutes at rated voltage and 20 °C, as defined in the datasheet.
• Rated Ripple — Rated ripple value listed at 1020 mArms for the 47 µF / 50 V entry in the datasheet table.
• Package & Mounting — Radial lead, can‑style package with 7.5 mm lead spacing and physical size L: 3.55 × D: 1.8 cm for reliable through‑hole assembly.
• Operating Range — Specified operating temperature range from −40 °C to +85 °C.
• Marking & Compliance — Printed marking in white on black sleeve; RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Hi‑Fi Speaker Crossover Networks — Designed specifically for crossover networks in Hi‑Fi sound systems where bi‑polar AC coupling is required.
• Passive Speaker Networks — Used in passive filters and networks to shape frequency response in multi‑driver speaker cabinets.
• Audio Equipment Repair and Maintenance — Suitable for replacement or refurbishment of audio components that require a bi‑polar electrolytic capacitor in a radial, through‑hole form factor.

Unique Advantages

• Designed for audio use: Bi‑polar construction and audio‑frequency loss angle specifications make this part well suited to crossover and AC‑coupled audio circuits.
• Clear electrical limits: Datasheet‑specified leakage current and tan δ values allow predictable performance and easier design verification.
• Robust rated ripple: Rated ripple of 1020 mArms for the 47 µF, 50 V entry supports sustained AC stress typical in crossover applications.
• Through‑hole reliability: Radial lead, can package with defined lead spacing and physical dimensions facilitates secure mounting and mechanical stability in speaker assemblies.
• Regulatory compliance: RoHS conformity helps meet environmental requirements for production and refurbishment projects.
• Clear identification: White printing on a black sleeve ensures easy polarity‑free identification and assembly orientation in production or repair workflows.
