UPM1A181MED

The UPM1A181MED is a radial-lead aluminum electrolytic capacitor from Nichicon's UPM series, designed for low-impedance, high-reliability decoupling and filtering tasks. It provides 180 µF nominal capacitance at a 10 V rating in a compact φ6.3 × 11 mm can with 2.5 mm lead spacing.

Engineered for demanding environments, this part supports an operating temperature range of −55°C to 105°C, includes AEC‑Q200 qualification, and is offered RoHS compliant. It is supplied in bulk or bag packing for through-hole assembly workflows.

Key Features

• Capacitance & Voltage: 180 µF nominal capacitance with a rated voltage of 10 V and tolerance of −20% to +20% for predictable energy storage and filtering.
• Low-impedance performance: Tangent of loss angle (tan δ) specified at 0.19 (measured at 20°C, 120 Hz, 10 V) to support low-loss filtering in power rails.
• Ripple current capability: Specified low-frequency ripple current of 110.7 mA (120 Hz) and high-frequency ripple current of 205 mA (200 kHz), enabling effective smoothing in switching and linear supplies.
• Leakage current: Rated leakage current of 54 µA for predictable standby and power-down behavior.
• Thermal and lifetime characteristics: Operating temperature −55°C to 105°C with a rated life/endurance of 2000 hours at 105°C.
• Package and mounting: Radial lead (polarized) can with physical size φ6.3 × 11 mm (L: 1.1 cm × D: 0.63 cm) and 2.5 mm lead spacing (±0.5 mm tolerance) for easy through-hole placement.
• Compliance & qualification: AEC‑Q200 listed and RoHS compliant for regulated designs and qualified supply chains.
• Packaging options & status: Available in Bulk (No Terminal Forming) or Bag Packing. Status: End Of Life.

Typical Applications

• Automotive electronics: AEC‑Q200 qualification and −55°C to 105°C rating make this capacitor suitable for control modules and sensor circuits requiring polarized bulk capacitance.
• Power supply filtering: Low impedance, specified tan δ, and defined ripple current ratings support decoupling and smoothing on DC‑DC converters and linear regulators.
• Embedded systems and controllers: Compact radial can and moderate leakage current provide stable hold-up and buffer capacitance for microcontroller and peripheral power rails.
• Point-of-load decoupling: The combination of 180 µF capacitance and high-frequency ripple capability helps reduce voltage ripple at local power nodes.

Unique Advantages

• Compact radial form factor: φ6.3 × 11 mm can and 2.5 mm lead spacing simplify placement in dense through-hole layouts.
• Clear ripple and loss specifications: Explicit low- and high-frequency ripple current numbers plus tan δ (0.19) let designers size capacitors for real-world switching and filtering demands.
• Wide operating temperature range: −55°C to 105°C supports operation across harsh and variable thermal environments.
• Qualified for automotive designs: AEC‑Q200 listing provides a verifiable qualification pathway for automotive and similar high-reliability applications.
• Predictable leakage behavior: Specified leakage current (54 µA) enables power budgeting and standby-state planning in low-current designs.
• Regulatory compliance: RoHS compliance aligns with environmental and manufacturing requirements.
