Overview of UDB1H330MHM – Bi-Polarized Aluminum Electrolytic Capacitor for Speaker Networks
The UDB1H330MHM is a bi-polarized aluminum electrolytic capacitor in a radial can package, engineered for use in speaker crossover networks and other general-purpose audio applications. It delivers 33 µF capacitance at a 50 V rating with a radial lead form factor and is RoHS compliant.
Note: This product is scheduled to be discontinued and is not recommended for new designs.
Key Features
- Capacitance & Voltage — 33 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance (measured at 1 kHz).
- Bi-Polarized Construction — Bi-polar design suitable for AC-coupled applications typical in speaker crossover networks.
- Audio-Oriented Electricals — Tangent of loss angle (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). For this part the datasheet lists a leakage current of 49.5 μA (after 5 minutes at 20°C).
- Ripple & Continuous Current Ratings — Allowable continuous current characteristics are specified (600 Hz reference) with a rated ripple of 800 mArms for this capacitance/size.
- Package & Mounting — Radial lead, can-style package with 7.5 mm lead spacing and nominal case dimensions of 16 × 30.5 mm (D × L), suitable for through-hole assembly and replacement.
- Operating Range — Specified operating temperature range of −40 °C to +85 °C for typical audio and general-purpose environments.
- RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
Typical Applications
- Hi‑Fi Speaker Crossover Networks — Bi-polarized capacitor construction and audio-oriented electrical specifications make it suited for passive crossover sections in home and pro audio speaker systems.
- Passive Audio Filters and Tone Controls — 33 µF/50 V rating and low tan δ support use in midrange/bass filter networks and passive equalization circuits.
- General-Purpose Audio Electronics — Radial through-hole packaging and defined ripple/current ratings simplify replacement and service in amplifiers, crossovers, and other audio equipment.
Unique Advantages
- Designed for Audio Crossovers: Specified and marketed for speaker network use, aligning electrical characteristics with crossover filter needs.
- Bi‑Polarized Flexibility: Allows AC applications without polarity concerns common in passive audio circuits.
- Measured Audio Parameters: Datasheet-provided tan δ and leakage figures enable predictable audio performance and easier specification matching.
- Through‑Hole Robustness: Radial can package and 7.5 mm lead spacing provide mechanical stability and straightforward PCB assembly or replacement.
- RoHS Compliance: Conforms to current RoHS directives for regulatory compatibility in applicable markets.
