UCQ1A330MCL1GB

The UCQ1A330MCL1GB is a chip‑type aluminum electrolytic capacitor from Nichicon’s UCQ series designed for surface‑mount applications. It combines a compact SMD can package with a wide operating temperature range and specifications suitable for audio and automotive electronic designs.

Key value propositions include AEC‑Q200 qualification, RoHS compliance, compatibility with automated carrier‑tape mounting, and electrical characteristics tailored for low‑voltage decoupling and filtering in compact assemblies.

Key Features

• Electrical Characteristics — 33 µF capacitance at a rated voltage of 10 V with ±20% tolerance (120 Hz, 20°C). Polarized aluminum electrolytic type suited for DC decoupling and filtering.
• Temperature & Endurance — Specified operating temperature range of −55°C to +105°C. Rated for 1000 hours at 105°C (lifetime at temperature as specified).
• Reliability & Standards — AEC‑Q200 qualified and RoHS compliant, supporting use in environments requiring industry reliability recognition and restricted‑substance compliance.
• Package & Mounting — Chip can SMD package (radial, can‑SMD); nominal dimensions L: 4.5 × D: 5 mm with maximum seated height 4.5 mm and recommended land pattern 5.3 × 5.3 mm. Designed for automatic mounting machines using carrier tape.
• AC Performance — Ripple current capability of 30 mA at 120 Hz and 45 mA at 10 kHz; leakage current after 2 minutes at 20°C is ≤ 0.01CV or 3 µA (whichever is greater) per series specification.
• Low‑temperature Stability — Impedance stability characterized by Z(−25°C)/Z(+20°C) = 3 and Z(−40°C)/Z(+20°C) = 5 at the 10 V rating (series measurement conditions).
• Soldering Robustness — Meets resistance to soldering heat requirements (30 s on a 250°C hot plate) with capacitance change within ±10% and no increase in leakage or tan δ beyond specified limits.

Typical Applications

• Automotive Electronics — Use in automotive control and auxiliary circuits where AEC‑Q200 qualification and a wide −55°C to +105°C temperature range are required.
• Audio Equipment — Chip‑type acoustic series design suited for audio circuitry requiring compact SMD electrolytic capacitors for coupling, decoupling, and power filtering.
• Automated PCB Assembly — Designed for carrier‑tape feed and automatic placement in high‑volume surface‑mount production.

Unique Advantages

• AEC‑Q200 Qualification: Provides a recognized reliability baseline for demanding applications, supporting use in qualification‑driven designs.
• Wide Operating Temperature: −55°C to +105°C rating enables use across broad environmental conditions encountered in automotive and industrial electronics.
• Compact SMD Can Package: Small footprint (L:4.5 × D:5 mm) and low seated height help save board space in dense assemblies.
• Assembly‑friendly Design: Carrier‑tape compatibility simplifies integration into automated pick‑and‑place workflows.
• Verified Electrical Performance: Clear ripple current, leakage, and impedance specifications allow straightforward selection for decoupling and low‑voltage filtering tasks.
