UCK1V242MNJ1MS

The UCK1V242MNJ1MS is a chip‑type, low‑impedance aluminum electrolytic capacitor from Nichicon’s UCK series designed for surface‑mount assembly. Built for automotive applications, it combines high capacitance (2.4 mF) at 35 V with a wide operating temperature range from −55°C to +105°C and AEC‑Q200 qualification for demanding environments.

Engineered for automated assembly (carrier tape compatible) and RoHS compliance, this part delivers bulk energy storage and ripple handling in compact SMD radial can packaging suitable for high‑reliability electronic modules.

Key Features

• Capacitance & Voltage — 2.4 mF (2400 μF) rated at 35 V provides substantial bulk capacitance for power smoothing and energy buffering.
• Low Impedance Construction — Chip‑type, low‑impedance design optimized for improved ripple handling and stable performance across frequency (rated ripple current: 1.03 A at 120 Hz, 2.06 A at 10 kHz).
• Automotive‑Grade Reliability — AEC‑Q200 qualified and specified for endurance: 5000 hours at 105°C, supporting long‑term operation in harsh temperature conditions.
• Wide Temperature Range — Rated for −55°C to +105°C to meet thermal demands of automotive and other high‑temperature applications.
• Surface‑Mount Package — Radial can SMD package compatible with automatic mounting machines (carrier tape fed); compact footprint (L: 1.65 × D: 1.8 cm) with recommended land size L: 1.83 × W: 1.83 cm.
• Electrical Characteristics — Polarized capacitor with ±20% tolerance; leakage current specified as not more than 0.01 CV or 3 μA (whichever is greater) after 2 minutes at 20°C, and tan δ characteristics provided in the datasheet (measurement at 120 Hz, 20°C).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU and (EU)2015/863).

Typical Applications

• Automotive power electronics — Bulk energy storage and smoothing in vehicle power systems where AEC‑Q200 qualification and 105°C endurance are required.
• Control modules and ECUs — Stable decoupling and ripple suppression for electronic control units exposed to wide temperature ranges.
• On‑board infotainment and body electronics — Provides reliable bulk capacitance and low impedance for voltage rails in compact SMD form factors.
