UDB1H010MPM

The UDB1H010MPM is a bi‑polarized aluminum electrolytic capacitor optimized for audio equipment, specifically crossover networks in Hi‑Fi sound systems. It is a radial‑lead, can‑style capacitor offering a 1 µF capacitance at a 50 V rating with specifications tuned for low‑loss audio performance.

Key value comes from its bi‑polar construction and low tangent of loss angle at audio frequencies, together with compact packaging and RoHS compliance for straightforward integration into speaker network and audio filter designs.

Key Features

• Bi‑Polarized Construction Designed for speaker network and crossover applications where bipolar behavior is required.
• Capacitance & Voltage 1 µF rated capacitance with a 50 V rating and ±20% tolerance, suitable for typical Hi‑Fi crossover values.
• Low Loss at Audio Frequencies Tangent of loss angle (tan δ) ≤ 0.10 at 1 kHz (≤ 0.15 at 5 kHz), supporting minimal signal loss in the audible band.
• Leakage Current Leakage current specified as not more than 0.03CV or 3 µA (whichever is greater) after 5 minutes at 20 °C, enabling stable performance in DC‑biased circuits.
• Compact Radial Can Package Radial lead, can‑style package with lead spacing 3.5 mm (±0.5 mm) and physical size approximately 8 × 11.5 mm (øD × L), for easy PCB mounting or point‑to‑point wiring.
• Rated Ripple Current Rated ripple current 205 mArms at 20 kHz (per datasheet entry for this part), useful for evaluating thermal and ripple handling in audio crossover circuits.
• Environmental Compliance & Identification RoHS compliant; marked with white letters on a black sleeve for clear identification.

Typical Applications

• Hi‑Fi Speaker Crossovers Use as the signal‑path capacitor in passive crossover networks where bipolar behavior and low audio‑frequency loss are required.
• Audio Filters Suitable for bandpass and high‑order filter sections in audio equipment requiring stable 1 µF values at up to 50 V.
• Consumer and Pro Audio Equipment Integration into speaker enclosures, amplifiers’ passive networks, and other audio signal conditioning circuits.

Unique Advantages

• Audio‑Focused Electrical Characteristics Low tan δ at 1 kHz and defined ripple handling help preserve signal fidelity in crossover and filter circuits.
• Bipolar Design for Simplified Implementation Eliminates the need for polarity orientation in AC or bipolar signal paths commonly found in speaker networks.
• Compact Radial Can Small footprint (approximately 8 × 11.5 mm) and 3.5 mm lead spacing provide flexible mounting options for compact loudspeaker designs.
• Predictable Leakage Behavior Leakage current specified by the 0.03CV or 3 µA limit enables designers to account for DC shifts and long‑term stability.
• RoHS Compliant and Clearly Marked Conforms to RoHS and is printed with white lettering on a black sleeve for quick visual identification during assembly and service.
