UDB1H100MHM

The UDB1H100MHM is a bi‑polar aluminum electrolytic capacitor engineered for audio applications, specifically designed for crossover networks in Hi‑Fi sound systems. Its bi‑polar construction supports AC coupling in passive speaker filters and other non‑polar audio circuits.

Packaged in a radial can with a compact 12.5 × 25 mm case and 5 mm lead spacing, the UDB1H100MHM combines audio‑focused electrical characteristics with RoHS compliance for use in general‑purpose audio assemblies operating from ‑40 °C to +85 °C.

Key Features

• Electrical Rating — 10 µF capacitance at a rated voltage of 50 V with tolerance ±20% (measured at 1 kHz).
• Bi‑Polarized Design — Built for AC applications such as speaker crossover networks where non‑polar capacitance is required.
• Audio Performance Parameters — Low loss characteristics with tan δ ≤ 0.10 at 1 kHz and ≤ 0.15 at 5 kHz; leakage current specified as not more than 0.03CV or 3 µA (whichever is greater) after 5 minutes at 20 °C.
• Allowable Ripple — Rated ripple current 600 mArms at 2 kHz, providing defined continuous current capability for audio ripple conditions.
• Package & Mounting — Radial lead, can package with 5 mm lead spacing and case dimensions φ12.5 × 25 mm (length × diameter), suitable for through‑hole PCB mounting and replacement applications.
• Environment & Identification — Operates across a −40 °C to +85 °C temperature range and is RoHS‑compliant; parts are printed with white lettering on a black sleeve for clear identification.

Typical Applications

• Hi‑Fi Speaker Crossovers — Provides bi‑polar AC capacitance for passive crossover networks to shape driver frequency response.
• Passive Audio Filters — Used in tone controls and filter sections where non‑polar capacitors are required to handle alternating signals.
• Audio Equipment Repair & Maintenance — Suitable as a replacement component for radial‑lead audio capacitors with matching form factor and electrical ratings.

Unique Advantages

• Designed for Audio Crossovers: Bi‑polar construction enables direct use in AC‑coupled crossover circuits without polarity constraints.
• Defined Audio Loss Characteristics: Specified tan δ values at 1 kHz and 5 kHz allow designers to account for loss in filter design and achieve predictable audio performance.
• Measured Leakage and Ripple Ratings: Clear leakage current and rated ripple current (600 mArms at 2 kHz) provide verifiable limits for reliability in audio ripple conditions.
• Compact Radial Package: φ12.5 × 25 mm can and 5 mm lead spacing simplify through‑hole mounting and mechanical replacement in existing assemblies.
• RoHS Compliant and Marked: Environmentally compliant construction with white-on-black sleeve marking for easy identification during assembly and service.
