UDB1H220MHM

The UDB1H220MHM is a bi‑polarized aluminum electrolytic capacitor engineered for audio crossover networks, specifically in Hi‑Fi speaker systems. It delivers a 22 µF capacitance at a 50 V rating in a radial‑lead can package designed for straightforward PCB mounting and audio circuit integration.

Key attributes include a compact 16 × 25 mm case, a wide operating temperature range of –40°C to +85°C, and RoHS compliance. Note: this product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Bi‑Polarized Construction Suitable for AC coupling and speaker crossover use where non‑polar operation is required.
• Electrical Ratings 22 µF capacitance with a 50 V rated voltage and ±20% tolerance (measured at 1 kHz).
• Loss and Leakage Low loss characteristics with tan δ ≤ 0.10 at 1 kHz and ≤ 0.15 at 5 kHz; leakage current per the datasheet is 33 µA (measured at 20°C after 5 minutes).
• Ripple and Continuous Current Rated ripple current listed as 740 mArms for the 22 µF / 50 V size; allowable continuous current frequency for this part is indicated as 900 Hz in the datasheet.
• Mechanical and Mounting Radial lead, can‑style package with lead spacing of 7.5 mm and case dimensions φD × L = 16 × 25 mm (L: 2.5 cm × D: 1.6 cm).
• Environmental Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Marking Printed with white letters on a black sleeve for easy component identification on assemblies.

Typical Applications

• Hi‑Fi Speaker Crossover Networks Designed specifically for crossover sections where bi‑polarized capacitors are required to couple and shape audio frequency bands.
• Audio Signal Conditioning Applied in audio circuits for AC coupling, filter sections, and tonal shaping in consumer and pro‑audio equipment.
• General Purpose AC/Audio Circuits Useful in board‑level designs requiring a compact, radial bi‑polar electrolytic with moderate ripple handling and a broad temperature range.

Unique Advantages

• Audio‑focused Design Engineered specifically for speaker networks, providing specifications and form factor aligned to Hi‑Fi crossover requirements.
• Bi‑Polar Flexibility Non‑polarized construction enables use in AC and bidirectional signal paths without orientation constraints.
• Compact, PCB‑Friendly Package 16 × 25 mm radial can with 7.5 mm lead spacing simplifies layout for through‑hole audio boards and retrofit applications.
• Measured Performance Data Datasheet values for tan δ, leakage current (33 µA at 20°C after 5 minutes), and rated ripple (740 mArms) allow designers to validate performance against audio circuit requirements.
• RoHS Compliant Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements for reduced hazardous substances.

Why Choose UDB1H220MHM?

UDB1H220MHM is positioned for engineers and technicians building or servicing Hi‑Fi speaker crossover networks who need a purpose‑designed, bi‑polar aluminum electrolytic capacitor with documented electrical and mechanical characteristics. Its combination of 22 µF capacitance, 50 V rating, compact radial can, and audio‑focused specifications make it a practical choice for board‑level audio filtering and coupling.

Because this product is scheduled for discontinuation and is not recommended for new designs, it is especially suitable for repairs, maintenance, or continuation builds where matching existing component specifications and form factor is critical.
