UYA1K161MNS1MS

The UYA1K161MNS1MS is a Nichicon UYA-series chip-type aluminum electrolytic capacitor designed for surface-mount assembly and long-term operation in high-temperature environments. It combines a 160 µF capacitance with an 80 V rated voltage in a compact SMD radial-can package that is compatible with carrier-tape feeding for automated placement.

Targeted for demanding applications, the part delivers extended load life and temperature endurance—making it suitable for systems that require reliable bulk capacitance at elevated temperatures and under continuous operation.

Key Features

• Capacitance & Voltage — 160 µF rated capacitance with an 80 V rated voltage to support higher-voltage DC rail decoupling and energy storage in a compact SMD form factor.
• High‑temperature, long life — Extended load life of 5000 hours at 125 °C; endurance specification includes capacitance change within ±30% and leakage current maintained to initial limits after endurance testing.
• AEC‑Q200 Qualified — Meets AEC‑Q200 qualification for reliability in automotive-grade electronics.
• Wide operating temperature — Rated for −40 °C to 125 °C operating range, with low-temperature impedance stability (impedance ratio max ≈3 at −40 °C for the 80 V rating).
• Ripple handling — Specified ripple current of 325 mA at 120 Hz and 650 mA at 10 kHz, supporting AC load and high-frequency decoupling needs.
• Leakage and dissipation — Leakage current specified as not more than 0.01CV or 3 µA (whichever is greater) after 2 minutes at 20 °C; tan δ (loss angle) max 0.12 at 80 V (measured at 120 Hz, 20 °C).
• Surface-mount, tape-fed package — Chip-type radial can SMD constructed for automated mounting with carrier tape, enabling streamlined assembly.
• RoHS compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — Designed for automotive systems requiring high-temperature endurance and AEC‑Q200 qualification for reliability under automotive operating conditions.
• Power modules and DC rails — Provides bulk capacitance and ripple suppression at elevated voltages and temperatures where long life is required.
• High-temperature embedded systems — Suitable for surface-mount designs that operate across −40 °C to 125 °C and need predictable performance over extended periods.

Unique Advantages

• Extended high‑temperature durability: 5000 hours of rated-life at 125 °C ensures stable capacitance and leakage characteristics in high-temperature deployments.
• Automated assembly ready: Carrier-tape compatible chip package simplifies placement and reduces assembly cycle time for high-volume production.
• Automotive-grade reliability: AEC‑Q200 qualification provides a validated baseline for use in automotive electronic subsystems.
• Compact, high-voltage capability: 160 µF at 80 V in a small SMD radial-can footprint enables higher-voltage designs without large board area impact.
• Measurable performance specifications: Clear limits for leakage current, tan δ, and ripple current allow predictable electrical design and margining.
• RoHS compliance: Environmental compliance for global product integration.
