UCQ1C471MCL1GS

The UCQ1C471MCL1GS is a Nichicon UCQ series chip‑type aluminum electrolytic capacitor designed for audio use and automated SMD assembly. It is a polarized, radial can SMD component optimized for wide temperature operation and applications that require AEC‑Q200 qualification and RoHS compliance.

Key value propositions include a 470 µF capacitance at 16 V rating, a wide operating temperature range from −55 °C to +105 °C, and endurance performance specified for 2000 hours at 105 °C—features that support reliable performance in audio and automotive electronics.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C), suitable for bulk decoupling and audio smoothing functions.
• Wide Temperature Range — Specified operating temperature from −55 °C to +105 °C, enabling use across extended environmental conditions.
• Reliability & Qualification — AEC‑Q200 qualified and RoHS compliant; endurance specified as 2000 hours at 105 °C with defined limits for capacitance change, tan δ and leakage current.
• Electrical Performance — Low leakage current (after 2 minutes at rated voltage: ≤ 0.01CV or 3 µA, whichever is greater); tan δ max 0.22 at 16 V (measured at 120 Hz, 20 °C); ripple current ratings of 400 mA at 120 Hz and 600 mA at 10 kHz.
• Low‑Temperature Stability — Impedance stability characterized by Z(−25 °C)/Z(+20 °C) = 2 and Z(−40 °C)/Z(+20 °C) = 4 at the 16 V rating (measurement frequency 120 Hz), for predictable performance in cold conditions.
• Package & Assembly — Chip‑type radial can SMD package designed for automatic mounting machines with carrier tape; surface mount land size specified as 1.03 cm × 1.03 cm.
• Marking — Black print on the case top for positive part identification after placement.

Typical Applications

• Automotive Audio Systems — Designed for in‑vehicle audio and infotainment modules where AEC‑Q200 qualification and wide temperature operation are required.
• Consumer Audio Equipment — Suitable for SMD audio circuits that need reliable bulk capacitance and low leakage for signal smoothing and power filtering.
• Embedded Power Filtering — Use in power supply decoupling and smoothing on compact SMD boards where automated placement and stable ripple handling are needed.

Unique Advantages

• AEC‑Q200 Qualified: Provides a documented qualification level for automotive designs that require components tested to industry reliability criteria.
• Wide Temperature Capability: −55 °C to +105 °C rating supports systems exposed to harsh environmental ranges without sacrificing capacitance stability.
• High Endurance at Elevated Temperature: Rated for 2000 hours at 105 °C with specified limits on capacitance change, tan δ and leakage current—helpful for long‑life deployments.
• Measured Low Leakage: Leakage current defined as ≤ 0.01CV or 3 µA (whichever is greater) after two minutes, aiding low‑current and standby applications.
• Defined Ripple Handling: Specified ripple current values at both low and high frequencies (400 mA at 120 Hz, 600 mA at 10 kHz) to guide thermal and lifetime budgeting in designs.
• SMD‑Friendly Form Factor: Chip‑type radial can package and carrier‑tape compatibility streamline automated assembly for high‑volume manufacture.
