UDB1H1R5MPM

The UDB1H1R5MPM is a bi‑polarized aluminum electrolytic capacitor engineered for audio applications. It is part of Nichicon's UDB series and is optimized for use in crossover networks and other Hi‑Fi sound system circuits.

Offered in a compact radial can package, this 1.5 µF, 50 V capacitor provides audio‑oriented electrical characteristics and RoHS compliance for general purpose electronic and audio equipment designs.

Key Features

• Bi‑Polarized Audio Design Specifically designed for audio use and speaker network crossovers, enabling AC‑coupled applications without polarization constraints.
• Electrical Characteristics 1.5 µF capacitance at 50 V rated voltage with ±20% tolerance (measured at 1 kHz).
• Low Loss at Audio Frequencies Tangent of loss angle (tan δ) of 0.10 or less at 1 kHz and 0.15 or less at 5 kHz, supporting low‑loss signal paths in audio circuits.
• Low Leakage Current Leakage current not more than 0.03CV or 3 μA (whichever is greater) after rated voltage is applied for 5 minutes at 20 °C.
• Package and Mounting Radial lead, can package with 3.5 mm lead spacing, standard radial mounting for through‑hole PCBs.
• Compact Physical Size Case dimensions L: 1.15 × D: 0.8 cm (8 × 11.5 mm case), suited for space‑constrained audio PCB layouts.
• Operating Temperature Rated for −40 °C to +85 °C operation to match typical electronics and audio equipment environments.
• Regulatory RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Hi‑Fi Speaker Crossover Networks — Used as the bi‑polarized coupling and filtering capacitor in crossover circuits for accurate frequency splitting and phase behavior.
• Audio Filters and Tone Controls — Suitable for signal path capacitors in passive filter stages where low loss at audio frequencies is required.
• General Purpose Electronic Circuits — Radial through‑hole mounting and compact size make it useful for space‑limited boards in consumer audio and related electronics.

Unique Advantages

• Designed for Audio Networks: The bi‑polarized construction aligns with speaker crossover requirements, reducing the need for polarity considerations in AC audio paths.
• Measurable Low Loss: tan δ ratings at 1 kHz and 5 kHz indicate controlled dissipation for cleaner audio signal handling in passive circuits.
• Predictable Leakage Performance: Specified leakage limits (0.03CV or 3 μA) support reliable circuit biasing and long‑term stability after voltage application.
• Compact Radial Can: 8 × 11.5 mm case and 3.5 mm lead spacing provide a small footprint and easy through‑hole assembly for retrofit and OEM boards.
• Wide Operating Temperature: −40 °C to +85 °C rating supports typical consumer and professional audio equipment operating ranges.
• RoHS Compliance: Conforms to applicable RoHS directives for environmentally conscious designs.
