UBY2A161MHL

The UBY2A161MHL is a high-reliability miniature aluminum electrolytic capacitor in a radial-lead can designed for demanding environments. It delivers 160 µF capacitance at a 100 V rating and is optimized for power‑supply smoothing and decoupling in control electronics.

Standard features include a wide operating temperature range of -40 °C to 135 °C, AEC‑Q200 qualification, and elevated ripple-current capability—making it well suited for automotive control circuits and other applications requiring long-term stability under thermal and electrical stress.

Key Features

• Capacitance & Voltage — 160 µF nominal capacitance with a 100 V rated voltage and a tolerance of -20% to +20% (measured at 120 Hz, 20 °C).
• High Temperature Endurance — Rated for operation from -40 °C to 135 °C with an endurance specification of 2000 hours at 135 °C (for 63 to 100 V parts).
• Low Impedance / High Ripple Capability — Low ESR of 74 mΩ at 100 kHz and rated ripple currents of 568 mA at 120 Hz and 1.42 A at 100 kHz support robust filtering under combined DC and AC stress.
• Reliability & Qualification — AEC‑Q200 qualified and specified as a high‑reliability UBY series part for automotive and industrial control use cases.
• Leakage & Loss — Specified leakage current of 480 µA and tan δ (DF) of 0.08 at 20 °C, 120 Hz for the 100 V rating.
• Compact Radial Package — φ12.5 mm × 20 mm can with 5.0 mm lead spacing (±0.5 mm) in a radial leaded form for through‑hole mounting; available in bulk or bag packing.

Typical Applications

• Automotive Control Circuits — Suited for control modules where high ripple handling and elevated temperature endurance are required.
• Electric Power Steering — Provides stable decoupling and energy buffering in steering control electronics exposed to high thermal and electrical stress.
• Direct Injection Engine Drive — Supports power-supply smoothing in injection drive circuits that demand reliable performance at high temperature.
• Power-Supply Filtering — Effective for high-frequency and low-frequency ripple suppression in compact, through‑hole designs.

Unique Advantages

• High ripple-current handling: Rated for 568 mA at 120 Hz and 1.42 A at 100 kHz, enabling improved smoothing under combined DC bias and AC ripple.
• Low ESR at high frequency: 74 mΩ at 100 kHz reduces voltage drop and heating during high-frequency switching events, improving regulator stability.
• Wide operating temperature range: -40 °C to 135 °C supports deployment in elevated-temperature environments without compromising performance.
• AEC‑Q200 qualification: Provides a documented reliability baseline for use in automotive-grade systems and other applications requiring industry-recognized qualification.
• Compact, serviceable form factor: φ12.5 × 20 mm radial can with 5 mm lead spacing simplifies replacement and layout in through‑hole assemblies.
• Designed for long-term endurance: Specified for 2000 hours at 135 °C (63–100 V range), offering predictable life characteristics under sustained thermal stress.
