UCQ1E100MCL1GB

The UCQ1E100MCL1GB is a surface‑mount aluminum electrolytic capacitor from Nichicon’s UCQ series. It is a chip‑type, audio‑oriented part designed for compact SMD assembly with a wide operating temperature range.

With a rated capacitance of 10 µF at 25 V, AEC‑Q200 qualification, and a temperature range of −55 °C to +105 °C, this device targets automotive and audio equipment applications that require compact, reliable decoupling and smoothing in harsh environments.

Key Features

• Capacitance & Voltage — 10 µF nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20% (120 Hz, 20 °C).
• Low Loss — tan δ (DF) of 0.16 measured at 20 °C and 120 Hz, supporting stable AC performance for audio and power‑supply circuits.
• Ripple Current Handling — Low‑frequency ripple current of 30 mA (120 Hz) and high‑frequency ripple current of 45 mA (10 kHz) for decoupling and filtering duties.
• Low Leakage — Leakage current specified at 3 µA, minimizing standby current draw.
• Wide Temperature & Endurance — Operating range −55 °C to +105 °C with rated life of 1000 hours at 105 °C (endurance condition for the 4.5 mm length variant).
• Compact SMD Package — Cylindrical chip package φ5 × 4.5L (L: 4.5 mm × D: 5 mm) suitable for space‑constrained boards; surface‑mount land size L: 5.3 × W: 5.3 mm.
• Assembly‑Friendly Packaging — Supplied in embossed carrier taping for automated pick‑and‑place mounting.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant per product data.

Typical Applications

• Automotive Electronics — Designed for use in automotive electronic modules where AEC‑Q200 qualification and a wide temperature range are required.
• Audio Equipment — Chip‑type UCQ series specification for audio use makes it suitable for decoupling and smoothing in audio signal‑chain power sections.
• Compact SMD Power Filtering — Small φ5 × 4.5 mm package fits tight board layouts for local decoupling and bulk smoothing in compact electronics.

Unique Advantages

• Compact SMD chip format: φ5 × 4.5 mm dimensions enable space savings on densely populated PCBs.
• Wide environmental tolerance: Rated for −55 °C to +105 °C to maintain performance across harsh temperature ranges.
• AEC‑Q200 qualification: Provides the documented qualification status required for automotive design processes.
• Low leakage and defined loss characteristics: 3 µA leakage current and tan δ = 0.16 (25 V, 120 Hz) support stable low‑noise power rails.
• Assembly ready: Embossed carrier taping supports automated mounting for high‑volume production.
• Endurance for high‑temperature operation: Specified 1000 hours at 105 °C for the 4.5 mm length variant, useful for long‑life deployments.
