Overview of UCM1H122MNS1MS – 1200 µF, 50 V Surface Mount Aluminum Electrolytic Capacitor

The UCM1H122MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount radial can package. It delivers 1200 µF capacitance at a 50 V rating, designed for automated assembly with embossed carrier taping.

Engineered for demanding environments, this part is AEC-Q200 qualified and rated for operation from -55°C to 105°C with an endurance of 5000 hours at 105°C, making it suitable for automotive applications that require robust power filtering and high ripple handling.

Key Features

  • Capacitance and Voltage: 1.2 mF (1200 µF) nominal capacitance with a 50 V rated voltage and tolerance of -20% to +20%.
  • Low Impedance, Chip Type: Chip-type construction optimized for low impedance characteristics, supporting stable performance in power circuits.
  • Ripple Current Capability: Handles 1.22 A at 120 Hz (low frequency) and 2.44 A at 10 kHz (high frequency), supporting both low- and high-frequency ripple conditions.
  • Loss Tangent (tan δ): tan δ = 0.10 measured at 20°C, 120 Hz, indicating controlled dielectric losses at the rated voltage.
  • Leakage Current: Specified leakage current of 600 µA.
  • Temperature and Endurance: Operating range from -55°C to 105°C with a rated lifetime of 5000 hours at 105°C.
  • Package and Mounting: Surface-mount radial can, size φ16 × 21.5 mm, with recommended surface-mount land size L: 1.63 × W: 1.63 cm; supplied in embossed carrier taping for automated placement.
  • Qualification and Compliance: AEC-Q200 rated and RoHS compliant for regulated production environments.
  • Vibration Resistant: Designed with vibration resistance suitable for mechanically demanding applications.

Typical Applications

  • Automotive power electronics — Bulk smoothing and energy buffering in in-vehicle power systems where 50 V rating and high ripple handling are required.
  • Control modules and ECUs — Local power filtering for electronic control units operating across -55°C to 105°C with long endurance at elevated temperature.
  • Power supply filtering — Decoupling and ripple suppression in DC-DC converters and intermediate bus capacitors that demand 1200 µF capacitance and controlled loss characteristics.

Unique Advantages

  • High ripple tolerance: Rated 1.22 A (120 Hz) and 2.44 A (10 kHz) allows reliable handling of both low- and high-frequency ripple in power circuits.
  • Wide operating temperature: −55°C to 105°C supports deployment in harsh thermal environments common in automotive electronics.
  • Long endurance at high temperature: 5000 hours at 105°C provides predictable life performance for long-term designs.
  • AEC-Q200 qualification: Industry-recognized qualification for demanding electronic applications, supporting use in regulated automotive designs.
  • Surface-mount, assembly-friendly packaging: Embossed carrier taping and chip-type SMD can footprint streamline automated placement and reduce handling complexity.
  • Low loss characteristics: Tan δ = 0.10 at 20°C, 120 Hz helps maintain efficiency in filtering and decoupling applications.
