UES1H4R7MEM

The UES1H4R7MEM is a bi‑polarized aluminum electrolytic capacitor from Nichicon’s MUSE acoustic series, designed for audio signal circuits. Its construction and electrical characteristics are targeted at audio applications that require bi‑polar operation, compact radial‑lead packaging, and RoHS compliance.

Key Features

• Bi‑polarized Audio Design Bi‑polar construction from the Nichicon MUSE acoustic series, suited specifically for audio signal circuits.
• Rated Capacitance & Voltage 4.7 µF capacitance rated at 50 V with a tolerance of ±20%.
• Electrical Loss and Leakage Series specifications include a maximum tan δ of 0.12 at 50 V (measured at 120 Hz, 20°C) and a leakage current limit defined as not more than 0.03CV (µA) after one minute at 20°C.
• Temperature Performance & Endurance Operating temperature range −40°C to +85°C. Endurance specified as 1000 hours at 85°C with polarity inversion every 250 hours, with allowable capacitance change within ±20% after test.
• Compact Radial‑Lead Package Radial lead, can‑style package with lead spacing of 2.5 mm and physical size L: 1.1 × D: 0.63 cm; seated height max 1.1 cm.
• Standards Compliance Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Signal Paths Used in audio circuits for coupling, decoupling, and signal processing where bi‑polar operation is required.
• Analog Front‑Ends Suited for analog audio stages and preamplifiers that benefit from MUSE acoustic series characteristics.
• Compact Audio Devices Small radial can footprint fits compact PCB layouts in consumer and professional audio equipment.

Unique Advantages
