UCX1V122MNJ1MS

The UCX1V122MNJ1MS is a chip‑type aluminum electrolytic capacitor from Nichicon’s UCX series engineered for continuous operation up to +135 °C. It delivers 1.2 mF capacitance at 35 V in a compact surface‑mount can package designed for automatic mounting with carrier tape.

With AEC‑Q200 qualification and RoHS compliance, this capacitor is targeted at high‑temperature electronics and automotive applications that require durable SMD power filtering and decoupling components with defined low‑temperature ESR behavior and long endurance.

Key Features

• Capacitance & Voltage — 1.2 mF nominal capacitance at a rated voltage of 35 V with tolerance of −20% to +20%.
• High‑Temperature Rating — Specified operating temperature range from −40 °C to +135 °C with endurance rated at 2000 hours at +135 °C.
• Low‑Temperature ESR Specification — ESR specified after the test at −40 °C; typical ESR is 50 mΩ measured at 100 kHz.
• Ripple Current Capability — Supports 700 mA ripple at 120 Hz and 1.4 A ripple at 10 kHz for robust filtering under varying frequency workloads.
• Surface‑Mount Can Package — Radial, can‑style SMD package sized L: 1.65 cm × D: 1.8 cm with recommended land size L: 1.83 cm × W: 1.83 cm; compatible with automatic mounting machines fed by carrier tape.
• Reliability & Compliance — AEC‑Q200 qualified and compliant to the RoHS directive (2011/65/EU, (EU)2015/863), supporting regulated and automotive design requirements.
• Polarized Electrolytic Construction — Polarized design for applications requiring electrolytic capacitance in compact SMD form factors.

Typical Applications

• Automotive Electronics — Designed for vehicle electronics requiring AEC‑Q200‑qualified capacitors that operate reliably to +135 °C.
• High‑Temperature Power Modules — Filtering and energy‑storage in power assemblies that experience elevated ambient or internal temperatures.
• Surface‑Mount Production — SMD can package and carrier‑tape compatibility for automated assembly workflows in high‑volume manufacturing.

Unique Advantages

• High‑temperature endurance: Rated for 2000 hours at +135 °C, enabling extended operation in hot environments.
• Defined low‑temperature behavior: ESR specification includes post‑test measurement at −40 °C, providing predictable performance across the full −40 °C to +135 °C range.
• Strong ripple handling: 700 mA at 120 Hz and 1.4 A at 10 kHz support effective smoothing and decoupling across common system frequencies.
• AEC‑Q200 qualification: Meets an established automotive component qualification for designs that require that level of reliability assurance.
• Manufacturing ready: Surface‑mount can package and carrier‑tape compatibility simplify placement in automated SMT lines.
• Regulatory compliance: RoHS compliant to 2011/65/EU and (EU)2015/863 for use in regulated markets.
