The UCQ1E101MCL1GS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly and audio-oriented applications. It combines compact SMD can packaging with wide operating temperature capability and AEC-Q200 qualification for demanding environments.

Intended for use in audio equipment and automotive electronics, this 100 µF, 25 V polarized capacitor delivers stable capacitance, defined leakage and loss characteristics, and a 2,000-hour endurance at elevated temperature for reliable power filtering and decoupling.

Key Features

• Capacitance and Voltage — 100 µF rated capacitance at 25 V for bulk decoupling and smoothing on power rails.
• Wide Temperature Range — Specified operating range from −55 °C to +105 °C to support designs exposed to broad thermal conditions.
• AEC-Q200 Qualified — Meets AEC-Q200 qualification as noted in the product data, supporting use in automotive-related electronics.
• Endurance — Rated for 2,000 hours at 105 °C under rated voltage, enabling long-term performance in elevated-temperature applications.
• Low-frequency and High-frequency Ripple Performance — Ripple current ratings of 120 mA at 120 Hz and 180 mA at 10 kHz to address both low- and high-frequency ripple demands.
• Polarized SMD Can Package — Compact radial can for surface-mount use; dimensions L: 7.7 × D: 6.3 mm with recommended land size L: 6.6 × W: 6.6 mm to support automated placement from carrier tape.
• Electrical Characteristics — Capacitance tolerance ±20% (120 Hz, 20 °C); leakage current after 2 minutes at 20 °C not more than 0.01CV or 3 µA (whichever greater); tan δ specified (120 Hz) with a maximum of 0.16 at 25 V.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863), meeting common environmental requirements.

Typical Applications

• Audio Equipment — Designed as a chip-type acoustic series for audio applications where compact SMD capacitors are required for power supply smoothing and signal-path decoupling.
• Automotive Electronics — AEC-Q200 qualification and wide temperature rating make it suitable for automotive electronic modules that require robust power decoupling.
• Surface-mount Assemblies — Carrier-tape compatible for automated placement in volume production of compact PCB assemblies.

Unique Advantages

• Automotive-grade Reliability: AEC-Q200 qualification and 2,000-hour endurance at 105 °C provide traceable qualification for automotive and high-reliability electronics.
• Wide Thermal Capability: −55 °C to +105 °C operation supports designs that must perform across extended environmental conditions.
• Measured Loss and Leakage: Specified tan δ and leakage current limits allow predictable behavior in precision audio and power circuits.
• Compact SMD Form Factor: Small can dimensions and defined land pattern enable space-efficient layouts and automated assembly workflows.
• Dual-frequency Ripple Ratings: Provided ripple current values at 120 Hz and 10 kHz help size the capacitor for both low- and high-frequency ripple management.
